Catastrophism Modern Synthesis of Evolution Uniformitarianism Geology - Uniformitarianism According to Larsen (2014: Chapter 4) and class discussions, what is a polymorphic trait? Provide two examples of polymorphic traits in modern humans? Also give one example of a monomorphic trait. (short answer) - A polymorphic trait is one in which at least two alleles exist at a frequency greater than 0.01%. Polymorphic traits in humans include eye, hair, and skin color, ABO blood type, and PTC tasting. In contrast, a monomorphic trait is one in which a single allele has become fixed, so all individuals express the same phenotype for that trait. Monomorphic traits in humans include the number of limbs and digits and walking on two feet (bipedalism). Why is the work of Alfred Russell Wallace considered when discussing the theory of evolution? 3Emily Charlene © All Rights Reserved 2025. He was an English naturalist who had arrived at many of the same conclusions as Darwin through his own research in the Amazon His work is not considered, as he was mistakenly credited with the theory of natural selection He was a British dog breeder who worked on artificial selection experiments in the same way Mendel worked on sweet peas to determine inheritance He was well known and gathered even more evidence to support evolution than Darwin, though from the Amazon rather than the Galapagos - He was an English naturalist who had arrived at many of the same conclusions as Darwin through his own research in the Amazon Archaeology is ___________ the study of human evolution largely devoted to recovering artifacts and building museum collections the study of the behavior and material culture of past human societies All of the above - the study of behavior and material culture of past human societies 4Emily Charlene © All Rights Reserved 2025. According to Clark Larsen (2014) in Chapter 2; why was Darwin's 1859 published theory of natural selection not widely accepted by his peers? What later scientific advance was critical to the subsequent broad acceptance of natural selection as a major force in evolutionary change? - Darwin's theory lacked a mechanism for the inheritance of desirable characteristics. Gregor Mendel discovered the principles of inheritance—that is, the basis for understanding how traits are transmitted from parent to offspring. Mendel's discovery that traits are passed as discrete units (genes) laid the foundation for our understanding of chromosomes and of population genetics. DNA replication produces __________ four identical daughter cells. two identical daughter cells. two single strands of DNA. none of the above. - two identical daughter cells In mammals, the male parent's gametes determine the
