Biologists From The United States

"Most of the oxygen we breathe is made by ocean plankton. And when animals left the seas in which life arose, they took seawater with them, in their bodies — an internal environment crucial for cellular survival. We are, in a sense, soft vessels of seawater."

"A couple of years ago I was participating as a writing coach in a "sea-mester," sailing 1,000 miles from Hawaii to , while students from Stanford University received lectures and closely supervised instruction and conducted independent projects on high-tech oceanography. These were smart kids, and the professors were superb. Five hundred miles from land, we got into a discussion on whether the ocean is a "wilderness." The consensus: Obviously it is; there was no sign of humanity, not another boat in sight. Everyone savored the thought: wilderness! But, I reminded everyone, we haven't caught a single or seen a or a . Wilderness? I don't think so. If the were covered with water, you wouldn't see that the buffalo were gone, either. There is no ocean wilderness. The whole ocean feels our effects, through fishing, pollution, dying s, , immortal plastics, oxygen-asphyxiated s, , and ."

"From the happy-go-lucky days of oil exploration and drilling, when a lot of easy sources were being found and easily managed, we're gotten ourselves into this sort of apocalyptic time. We're willing to destroy almost everything, risk almost anything, and go ahead with techniques for which we have no way of responding to the known problems. And that is truly an addiction in the real sense of the word, an addiction by which people destroy their own bodies to continue to have a supply of something that is killing them."

"Complexity science is a project aimed at unification, trying to establish principles that are common to all adaptive systems."

"I do view the march of technology as kind of inevitable. But I would like to accompany it with reason. And one form of reasoning that’s useful in these debates is to find precedence."

"I think the history of humanity is the history of our co-evolution with devices and artifacts that make our lives easier. And I think it's now a question from moral philosophy — not for science — to decide how we use them and what it would mean to be enslaved by them, whether we do so willingly or reluctantly and genuinely."

"We warn that models in population genetics should be treated with caution. Although they provide an important framework for testing historical hypotheses, they are oversimplifications. For example, the true ancestral populations of India were probably not homogeneous as we assume in our model, but instead were probably formed by clusters of related groups that mixed at different times. (Reich et al. 2009: 492)"

"The circularity of the ‘Ancestral North Indians’ (ANI) vs ‘Ancestral South Indians’ (ASI) concept is another case in point. Reich (2018) admits that he thought it up overnight simply to avert serious differences with his Indian collaborators. No precise definition was ever given to these two supposedly highly distinct groups; they were simply stated to be ‘genetically divergent’ (Reich et al. 2009) and were used in several subsequent studies as though they had been rigorously established. Elsewhere (Danino 2014), I showed that the populations sampled were very seriously restricted, since 18 states of India had either no representation or only one group represented in the 2009 study. Despite such a skewed distribution, Reich et al. exuded confidence in the newly coined terms and found it ‘tempting to assume that the population ancestral to ANI and CEU [Europeans] spoke ‘‘Proto-Indo-European’’ … ’ (Reich et al. 2009, p. 492) – a gratuitous association built, again, on circularity."

"“Whites” are not derived from a population that existed from time immemorial, as some people believe. Instead, “whites” represent a mixture of four ancient populations that lived 10,000 years ago and were each as different from one another as Europeans and East Asians are today."

"About ten thousand years ago there were at least four major populations in West Eurasia — the farmers of the Fertile Crescent, the farmers of Iran, the hunter-gatherers of central and western Europe, and the hunter-gatherers of eastern Europe. All these populations differed from one another as much as Europeans differ from East Asians today. Scholars interested in trying to create ancestry-based racial classifications, had they lived ten thousand years ago, would have categorized these groups as "races," even though none of these groups survives in unmixed form today."

"Ideologies that seek a return to a mythical purity are flying in the face of hard science."

"Ancient DNA available from this time in Anatolia shows no evidence of steppe ancestry similar to that in the Yamnaya (although the evidence here is circumstantial as no ancient DNA from the Hittites themselves has yet been published). This suggests to me that the most likely location of the population that first spoke an Indo-European language was south of the Caucasus Mountains, perhaps in present-day Iran or Armenia, because ancient DNA from people who lived there matches what we would expect for a source population both for the Yamnaya and for ancient Anatolians. If this scenario is right the population sent one branch up into the steppe-mixing with steppe hunter-gatherers in a one-to-one ratio to become the Yamnaya as described earlier- and another to Anatolia to found the ancestors of people there who spoke languages such as Hittite."

"People often think that Europeans are homogeneous group that arrived in a simple way there maybe 40 or 50 thousand years ago maybe based on the archaeology and just kind of sat there until they became the Europeans they are today, but that's probably not true: the Europeans today are a replacement population who came in much more recently and replaced the people who were there originally 40 thousand years ago."

"The mixture of highly differentiated populations is a recurrent process in our history."

"He and John Grehan are the only two scientists on the whole planet who subscribe to this red-ape hypothesis. ...I think he's completely wrong on this hypothesis of his, but I have his books on my shelf."

"A micromutation can produce what Goldschmidt would have described as macromutation leading to macroevolution. Since mutations in homeobox genes are inherited in the same way that earlier fruit-fly population geneticists understood the inheritance of the alleles for wing length or bristle number, we can appreciate that evolutionarily significant novelty—which, in turn, could result in the emergence of a new species—can be passed on from parent to child as easily and simply as eye color."

"As was demonstrated as long ago as the 1930s by the German experimental geneticist Hans Grüneberg, neither structural reduction or loss, nor structural addition, is a completely gradual process. Instead, the loss or gain of a structure is developmentally constrained to be more step-wise, or saltational."

"The observation of reduction in complexity in many groups or organisms after a structure has emerged in a full-blown state makes sense in terms of homeobox genes."

"The often heated and sometimes nasty debates that have taken place between gradualists and punctuationists, or between micromutationists and macromutationists, have been generated by the perception that there is only one evolutionary question, for which... there can be only one correct answer. ...But if we take a different approach, and assume that both sides of a typical evolutionary debate have something valid to offer, then the theoretical and methodological disagreements between different schools of thought may just be a matter of having the right answer to a different question."

"The Phoenicians were the Canaanites. Thus Phoenicia... was invaded by the Israelites, who eventually pushed the Phoenicians to the coastal fringe. Subsequently, the Israelites borrowed various cultural elements from the Phoenicians, including the first alphabet. Some groups of Israelites even adopted the god Ba'al and, presumably, the practice of child sacrifice."

"If Walter Garstang's suggestion is correct, and chordates did arise from a tunicate-like form by retaining the chordate features of their larval stage of development into adulthood, then the first chordates must have been affected by a regulatory mutation that kept the Manx gene activated for a longer period of time."

"The sudden appearance of novelty is not, as Otto Schindewolf emphasized, an unusual aspect of the fossil record."

"More than one hundred years ago, William Bateson suggested that studying the regulation and timing of development was the key to understanding evolutionary change. He was right."

"The corpses of water-dwelling animals often sink to the bottom and become covered with sediment. The sediment tends to protect the dead body and even at times retain an impression of its shape and external anatomical details. This environment then provides the means by which the bones of the skeleton are mineralized. ...most land animals die and fall to the ground, without any chance of a freak flood casting them into an environment more favorable to fossilization."

"The smaller the mammal, the more it is confined to smaller geographic areas. A small mammal is also more susceptible to subtle changes in climate and environment. ...On average, the absence or presence of smaller species provides more precise clues to past conditions in an area than does the information gained from study of the bone assemblages of the larger animals."

"The Bodo skull and the Kaprina and Shanidar Neandertal skeletons raise the possibility that two distinct, non-spaiens species of Homo had had rituals and cultural practices that we have assumed are only within the capacity of members of our own species."

"Becoming a rock does not ensure safety. ...The blasting of windblown sands, the pummeling of waves, the corrosive secretions of mosses and lichens, and even the steady rhythm of a stream can, in time, reduce a seemingly indestructible boulder to a grain of sand."

"The processes of bone preservation are such that the farther back in time we go, the less there is."

"There are always alternative interpretations of the same data. It is often the case, however, that the alternatives that are rejected are treated as if they don't exist. But they do. And we should be aware not only of their existence and potential viability, but of the possibility that the hypotheses that we might embrace so strongly today may very well be the rejects of tomorrow."

"The upper and lower ends of a humerus are like the brim and base of an urn. The shaft of the bone is like the belly of the urn. Fragments, even minute ones, of the detailed parts of a bone are like the indicator sherds of a broken urn. Fragments, even large ones, of the shaft of a bone are like the body sherds of a broken urn. Analyzing bones, after all, is very much like analyzing pottery."

"Science, especially evolutionary sciences, can only proceed from learning about theories of hypotheses that do not stand the test of time."

"Petrie found that certain types of pottery were characteristic of a particular phase of the Bronze Age, whereas other styles were found only a phase of the Iron Age, or only during the Hellenistic or Greek periods."

"I hope to... provide insights into the interpretation of "evidence" and the application of the "scientific method" so that you... will be more attuned to what scientists are saying, and why they may be saying it, and realize that the problems and issues that they are addressing are matters we can all think about critically."

"Some... resistance also came from the belief that preserved historical writings could provide all anyone needed to know about the habits of past civilizations. ...According to the archeologists, this site was supposed to have had an uninterrupted sequence of Israelite occupation... These archeologists "knew" that there had been a continual occupation of people practicing full-blown Jewish orthodoxy based on their interpretation of the preserved written records. ...But, to the extreme surprise of the dig's staff... one-third of the bones from the floor of the synagogue were pig. Anathema! ...directly beneath the floor of this synagogue... the first piece of bone I picked up was from the skull of a young human. Again, anathema! How could orthodox Jews build anything, much less a synagogue, over a human burial area? ...no reports on the site including my analyses have ever seen the light of day."

"From a succession of historians we learn of a particularly gruesome component of Carthaginian daily life: the routine and ritualized sacrificing of not just animals—animal sacrifice was a common religious activity of all Mediterranean cultures—but of infants and children. ...Greek and Roman historians were unanimous in their abhorrence of the Carthaginian practice..."

"There has been little morphological evidence offered since Darwin in support of the relatedness of humans and one or both of the African apes, but that, when the relationships among the extant humanoids are investigated cladistically in an evaluation of more than 200 morphological features, there are well over twice as many morphological synapomorphies in support of uniting humans with the orang-utan as with the African ape clad and very few in support of uniting the chimpanzee more closely with humans than with the gorilla."

"A "new" systematics will be forthcoming only when the urge to be "right" takes a back seat to the possibility that one is wrong."

"Although it may be extremely reasonable (especially from our present vantage point) to conclude that some part of human evolution, if not aspects of the diversification of hominoids in general, is indeed preserved in the fossil record of Africa, this does not in and of itself lead inexorably to the conclusion that humans and African apes are closely related."

"Greeks and Romans alike engaged openly in a variety of sanctioned atrocities, including adult human sacrifice. ...according to ...Cicero, human sacrifice was not restricted to the western Phoenicians but was widely accepted among Mediterranean societies as a pious act that would please the gods."

"It is frustrating to know, on the one hand, that every living thing on earth will have had a single, unique history—whether it be the life of an individual, of a civilization, of a species, of a diverse evolutionary group—and, on the other, to be constantly in the position of trying to discover it."

"Some students at BYU perceive general education as an unfortunate burden that does little for them professionally. I was rudely awakened to this perception the first time that I taught Biology 100. Having loved biology my entire life, I assumed that all 250 students in my class would be as enthusiastic as I was to study biology. I quickly learned that most of my students dreaded having to take the course and had little interest in the sciences. My challenge was to help them learn to reverently admire the intricate wonders of God's creation that are evident when we study life. General education is especially important at BYU, for here a thoughtful study of the arts and sciences can be, in President Kimball's words, "bathed in the light and color of the restored gospel". Let me share with you a few of my own experiences."

"I have always felt a deep reverence for the intricacy and beauty of nature. While I was an undergraduate student at BYU, I fell in love with biology, especially with genetics. As I studied the biological and physical sciences, I came to view the creation of life in a much broader sense than before. I now view creation not as something that occurred long ago but as a process that continues today in which we are given the sacred privilege to participate. Through the study of biology we are able to gain a glimpse of how the earth and all of life was, and still is, created. Several scientists have shared this sense of wonder as they have spoken of the forest canopy as a great cathedral or of microbes, plants, and animals as God's creations with whom we share the earth. For example, Francis Collins, who is the director of the human genome project, one of the greatest scientific undertakings in history, said:"

"Vibrant human diversity is now commonplace in major cities throughout the world. Some celebrate such a mix of human diversity. Others deplore it, preferring that so-called races be separated both geographically and reproductively. Even today, some people retain the once-popular belief that the 'white' race is superior in intellect, health, and other attributes. Although far more people reject the notion of white supremacy today than in the past, its legacy remains, as evidenced by economic stratification, ongoing segregation, and classification by racial categories. Even among those who reject the supposed superiority of a particular ethnicity over any other, the perception of distinct, genetically determined human races often persists."

"To understand who we are as a species, and why we vary as we do, we must examine our genetic diversity in the context of a common African origin, followed by intra- and intercontinental diasporas that transpired over a period of tens of thousands of years, culminating in an era of major migrations that reshuffled the worldwide human genetic construction over the past several thousand years and is still underway. Last, we must recognize that today’s human population is far larger, more diverse, and more complex than it ever has been. We are all related, more than seven billion of us, recent cousins to one another, and, ultimately, everyone is African."

"A significant minority of people fully reject human evolution, opting instead for the belief that humans were specially created with no prior evolutionary ancestry less than ten thousand years ago. Such beliefs are often infused with a non-scientific perception of different races and how the supposedly originated. And, in spite of overwhelming scientific evidence and changing social norms, a relatively large proportion of people still cling to past traditions of white supremacy and racism."

"The world's most prominent human population geneticists have publicly criticized the people who claim genetic research supports the notion of biological races, and the unfounded inferences derived from that notion."

"So-called racial differences in IQ scores are more a consequence of disparities in socioeconomic status and the quality of education than of any genetic differences between ethnic groups. Efforts to improve educational quality and opportunity can increase the economic benefits associated with increased educational achievement."

"Unfortunately, many people find it difficult to accept what current science tells us about the myth of race. It runs counter to what seem to be obvious racial distinctions, mostly in parts of the world where immigration history has juxtaposed people with discontinuous ancestral backgrounds in the same place. The racial categorizations that many of us have experienced throughout our lives have likewise inculcated a sense of racial division that is not easy to abandon. Regardless of what the science shows, the perception of race and the associated racial discrimination are unlikely to disappear soon. Furthermore, a scientific understanding of human evolutionary history challenges commonly-held religious beliefs that are based on literal interpretations of biblical history."

"Few features of humanity are as obvious as the wide array of inherited diversity visible in our outward features. It's also evident that people whose ancestry traces to a particular geographic region typically appear similar to one another and different from other geographic regions. Moreover, we as humans have an almost innate propensity to compartmentalize nearly everything into discrete categories, even when lines that distinguish those categories are complex, blurred, or nonexistent. As an inevitable consequence, people have been subjected to categorization into what we call human races throughout much of the past several centuries."

"Throughout the past several centuries, people have used the term race to describe groups of people in much the same way it was used in past centuries to describe groups of animals. People with ancestry from a particular region of tend to share certain inherited similar features, resembling their parents. However, the children of parents with substantially different ancestral backgrounds often have an appearance that is intermediate between that of their two parents, and in subsequent generations, the offspring may vary. In part because of the obvious similarities between animals and humans for how traits are inherited, and in part because of cultural, political, and religious traditions, notinos of racial purity and superiority have surged and ebbed yet persisted, crossing the boundaries of culture, geography, politics , and time. They are still with us today, and some of the most insidious actions based on notions of racial supremacy happened not long ago."
