A reasonable definition for a species is: O A distinct kind of animal. O A group of living things with functionally similar traits, for example, all creatures that can fly. A group of living things with taxonomically similar traits. O A group of taxonomically similar living things in which all healthy members can interbreed and produce fertile offspring.

In the following cladogram species A, B, C, and the root of the tree together represent what sort of group?
Fred and George are arguing over evolution. Fred posits that evolution can occur in any population as long as all members gradually undergo change. George disagrees; he thinks that individual memebers of the population do not change but instead have offspring with the trait(s) of interest and thus a population evolves over generations. Who is right? Choose the best answe a. Fred is right! As members of the population respond to the environment, they change to suit it better O b. Fred is right! All memebers of the population must change aroudn the same time O c. George is right Evolution occurs over generations as only the beneficial traits are passed onto the next generation. O d. George is right! Individuals don't change their alleles, but the offspring they have contributes to the change in population allele frequencies
Choose the answer that best describes Allopatric Speciation. evolution that occurs when populations are separated by behavioral traits. All of these answers are true O evolution that occurs when populations are separated by geographic or physical barriers. O evolution that occurs when populations live in different habitats or exploit different niches.
You are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? * Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. Microevolution is occurring in both variations. They are two separate species. Two species of toads are reproductively isolated due to the fact that one species mates in early summer and one in late summer. Both species of toads evolved from a common ancestor. What type of speciation occurred?* OAllopatric
Another way to say "Natural Selection" is: differential success in reproduction mutation selective breeding differential access to mating partners variation O preferential sex choices

Which part of these statements isn't right ? A species is a group of organisms that can potentially interbreed with one another to produce viable, fertile offspring. Speciation is when two new species form from one original one. Sympatric speciation occurs when there is a geographic separation of a population. Allopatric speciation occurs while the population remains in the same area. Adaptive radiation occurs when one species evolves into many to fill several different niches. Natural selection requires traits to be passed from parent to offspring, more offspring are produced than can survive creating competition, and inherited traits vary among offspring. Fossils, Anatomy and embryology, biogeography, and molecular biology all provide support for the theory of evolution. Evolution can be driven by many different things. Mutations are changes in DNA that create new alleles in a population. Gene flow is the flow of alleles in and out of a population resulting from the migration…
