When it comes to adaptation, survival of a species' trait through artificial selection depends on a) which trait is the fittest for the environment b) which trait humans desire to reproduce c) which trait is the oldest for the species d) which trait has more abundance in the population

Why do related species share homologous traits? Please choose all the FALSE options.  a) Related species have independently evolved homologous traits. b )Related species inherited homologous traits from a common ancestor. c ) Related species share homologous traits because they are found in the same geographical area. d) Related species have adapted to similar environments

Starting from a single wild canine species, humans have developed hundreds of breeds of domestic dogs. Which of the following statements is supported by this observation? 1) Natural selection had not occurred very frequently in the wild dog populations. 2) There was enough heritable variation in the wild canine species to create a variety of features. 3) Heritable variation is low; otherwise the there would be more wild dog species. 4) Most of the variation in domestic dog species is a result of variation in nutrition and training.

You are studying the evolution of resistance to pesticides in pea aphids. Some pea aphids are resistant to the pesticide (solid line) and some are susceptible to the pesticide (dotted line). You compare the fitness of resistant and susceptible aphids in environments with pesticide (exposed) and without pesticide (non-exposed) and produce the graph below: 1.0 non-exposed exposed Environment Fitness

According to Darwin’s model of evolution, evolution can only occur if there is some variation present among the individual members of a population. Which statement best describes the source of this variation among members of a species? A) individuals will vary depending on geography and climate B) variation exists because not all genes will be expressed C) variation among individuals may arise as a result of mutations in the genetic code D) variation exists because different individuals will have different access to food and other resources

Which of the following is correct concerning adaptations? (Choose one.) Group of answer choices a)They always increase an organism's ability to survive better than other individuals in the population. b)They can increase an organism's ability to survive better or reproduce better than other individuals, but not both at the same time. c)They increase an organism's ability to reproduce better than other individuals in the population, in a given environment. d)They result from any mechanism of evolution.

"The use or disuse of a trait explains why it evolved or was lost."   Please explain in detail why this is false and a misconception.

Although natural selection is sometimes called the survival of the fittest, it is ultimately a process of: a) differential reproduction b) differential consumption c) differential migration d) differential mutation

Which of the following processes and or mechanisms of evolution violate the assumptions of Hardy-Weinberg Equilibrium?  Select all that apply. Group of answer choices A) Natural selection B) Assortative mating C) Random mating D) Genetic drift E) Mutation

Explain, draw, and provide example of directional, stabilizing and disruptive selection.
