"If species had really arisen by the natural selection for impalpable differences, intermediate forms should abound, and the limits between species should be on the whole indefinite. As this conclusion…"

"I am well aware that some very eminent systematists regard the whole problem as solved. They hold as Darwin did that specific diversity has no physiological foundation or causation apart from adaptati…"

"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. Ha…"

"I well remember receiving from one of the most earnest of my seniors the friendly warning that it was waste of time to study variation, for "Darwin had swept the field." Parenthetically we may notice …"

"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 geog…"

"A list of some of his publications"

"Misconception was especially brought in by describing descent in terms of "blood". The common speech uses expressions such as consanguinity, pure-blooded, half-blood, and the like, which call up a mis…"

"In the light of the new knowledge various plausible, but frequently unsatisfying, suggestions put forward, especially by Wallace, Weismann, and their followers, as probable accounts of evolutionary pr…"

"That the variations are controlled by physiological law, we have now experimental proof; but that this control is guided ever so little in response to the needs of adaptation there is not the smallest…"

"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 worl…"

"In spite of Darwin's hopes, the acceptance of his views has led to no real improvement — scarcely indeed to any change at all in either the practice or aims of systematists. In a famous passage in the…"

"Of the contributions made during the essayist period three call for notice: Weismann deserves mention for his useful work in asking for the proof that "acquired characters" or, to speak more precisely…"

"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 i…"

"Under the guise of eugenic improvement and racial purity, and what the implementation of eugenic measures could supposedly do to improve human society, notions of racial superiority continued in popul…"

"Announcement of Appointment as a dean"

"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 fro…"

"The concept of evolution as proceeding through the gradual transformation of masses of individuals by the accumulation of impalpable changes is one that the study of genetics shows immediately to be f…"

"Since the belief in transmission of acquired adaptations arose from preconception rather than from evidence, it is worth observing that, rightly considered, the probability should surely be the other …"

"Few who are familiar with the facts that genetic research has revealed are now inclined to speculate as to the manner by which the process has been accomplished. Our knowledge of the nature and proper…"

"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…"

"Memory is a mystery as deep as any that even psychology can propound. Philosophers might perhaps encourage themselves to attack the problem of the nature of memory by reflecting that after all the pro…"

"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 …"

"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. Su…"

"A better understanding of what science tells us about human genetic diversity is of immense importance, particualrly because it dispels false notions of what race is."

"There are those who still believe that notions of racial purity are biologically and theologically sound, and therefore desirable, in spite of the fact that current genetic evidence has obliterated al…"

"Classification is real, but it is based much more on a set of social definitions than on genetic distinctions. Legally defined categories for race differ from one country to another, and they change o…"

"It was in the attempt to ascertain the interrelationships between species that experiments n genetics were first made. The words "evolution" and "origin of species" are now so intimately associated wi…"

"As systematic inquiry into the natural facts was begun it was at once found that the accepted ideas of variation were unfounded. Variation was seen very frequently to be a definite and specific phenom…"

"Truer notions of genetic physiology are given by the Hebrew expression "seed". If we speak of a man as "of the blood-royal" we think at once of plebeian dilution, and we wonder how much of the royal f…"

"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 biologi…"

"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 ancestr…"
