- Natural selection acts upon ____________________________, evolution upon _______________________________. What is the gene pool and how does natural selection act upon it? If a version of a gene confers an advantage to survival and reproduction, that version of the gene will be favored by natural selection and we can expect the frequency of that gene to ______________________ within the population over time. Versions of the gene that do not confer an advantage (or confer a disadvantage) should become _______________ prevalent . This generation to generation change in the gene pool is called ________________________. Changes to the genetic makeup of a population and the individuals within it can arise via two mechanisms. List and describe both. Both of these processes are ________________________________. Once created, new combinations of genes will be acted upon by _________new alleles_______________________.

True Falsearrow_forwardMeaningful evolution occurs when __________. ○ a heritable trait affects survival and fitness ○ a heritable changed trait gives an organism a fitness advantage ○ a changed trait gives an organism a disadvantage ○ environmental factors changearrow_forwardThis question will assess your understanding of popular thinking about Evolution by Natural Selection. The following interview appeared in the NY Times about the evolution of human skin. Your task is to read the interview and answer the question below: Claudia Dreifus. 2007. A Conversation with Dr NG Jablonski: Always Revealing, Human Skin Is an Anthropologist's Map. NYT 9 Jan 07. Interviewer: And what have you found? Scientist: .There was a tremendous takeoff in human evolution about two million years ago when primates who could no longer be called apes appeared in the savannahs of East Africa. These early humans ran long distances in open areas. In order to survive in the equatorial sun, they needed to cool their brains. Early humans evolved an increased number of sweat glands for that purpose, which in turn permitted their brain size to expand. As soon as we developed larger brains, our planning capacity increased, and this allowed people to disperse out of Africa. There's fossil…arrow_forward
- "Natural selection is the only mechanism of evolution." Please correct this statement in a meaningful wayarrow_forwardWhich the following statements about Darwin's theory of natural selection is true? O In order to reproduce more successfully, an individual must evolve so that it adapts to its environment. The natural environment consistently causes variation of certain traits in the population. O Individuals with inherited traits that are better suited to the local environment are more likely to survive and reproduce than less well-suited individuals. Natural selection, by its cumulative effects over long periods of time, could have caused random changes in ancestral species, thus giving rise to two or more descendant species.arrow_forwardWhich of the following statements regarding evolution is FALSE? evolution is a relatively slow process Oall of these statements are TRUE evolution operates at a variable speed transitional forms appear during periods of rapid evolutionary change evolution operates over the course of multiple generationsarrow_forward
