- Explain the main theme of evolution: “unity in diversity”.arrow_forwardWhat is meant by a mechanism of evolution?arrow_forwardDo you think the human race is continuing to evolve in a Darwinian, genetic sense? Are the genes of our species changing? Do not just write "yes" or "no," but explain why you think so. In addition, include in your explanation of how the mechanisms of evolution, such as natural selection, would be at play.arrow_forward
- Which of the following statements best characterizes genetic diversity in humans? 1.) There are far more genetic differences between populations/groups than there is variation within populations. 2.) Between-group differences in most phenotypic traits (e.g., athletic ability, performance on standardized tests, etc.) are mostly inherited and due to the effects of natural selection. 3.) The vast majority of polymorphisms (such as SNPs) in the genome are informative about a person's ancestry (in other words, you could get a pretty good idea of someone's ancestry by looking at their genotype at just about any random SNP in the genome). 4.) Humans have much lower levels of genetic diversity than most other animals.arrow_forwardBased on our current understanding of human biological variation, explain why different human “races” do not exist biologically. Explain why the “race” concept has no scientific basis. How can we, as a society, unlearn the outdated, unscientific ideas about “race”?arrow_forwardClarify why evolution occurs only in populations, not in individuals.arrow_forward
- Describe the present day theory of evolution. Describe the 4 basic causes of evolution: natural selection, mutation, genetic drift, and gene flow. Describe how each evolutionary force can influence the allele frequencies of a population. Describe sources of evidence for evolution. Identify common misconceptions about evolution. Identify common criticisms of evolution. Describe the evolution of COVID-19.arrow_forwardExplain how you think DNA, mutation, genotype, phenotype, and natural selection are all interconnected to cause evolution.arrow_forwardGenerally, will natural selection result in an increase or decrease in variation? Why does this happen, and how, in theory, will it affect evolution in the future?arrow_forward
