- You are studying the evolution of a trait in two species of snakes where both species can flatten themselves so that they can glide from tree to tree. You know that this trait is not present in the ancestor of all snakes. With this information, is the trait a homology? a. Yes b. No c. Only in one of the species. d. Not enough information to tell.which statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.1) Darwin's studies of Galapagos finches are well known in the study of evolution. These studies have been instrumental in helping us understand how new species evolved from pre-existing species. Which statement is true about the speciation of the Galapagos finches? A) The finches evolved traits to help them survive in different environments. B) The finches had different traits that influenced the environment in which they chose to live. C) Genetic variation occurred amongst the finches, giving some a genetic advantage in a changing environment, allowing them to better survive. D) Members of the original population evolved in such a way that it became impossible for individuals from the two new populations to interbreed. Not graded

Enumerate the scientist and cite their respective contributions in the development of evolutionary thought.Choose an organism that is a product of artificial selection. Give a brief description of your organism and its desired traits. What wild ancestor did it come from? Was it produced with selective breeding or genetic engineering (i.e. genetically modified)? What are the benefits of artificial selection in this case? Are there potential negative consequences?
- 1. Captive breeding programs can reestablish the populations of threatened species in the wild, but they failed in all cases. True or False? 2. Analogy is similarity due to convergent or parallel evolution. True or False?1.A) Adaptations to a Changing Environment• Explain why it is necessary for organisms to have the ability to adapt.• Why is the current environment making it difficult for organisms to adapt?• Explain how organisms develop adaptations.2. B) Artificial Selection• Explain how artificial selection is like natural selection.• Why are quail useful subjects for an experiment on selection? What other organisms share similar characteristics?1.A small group of turtles float on a log to an island and establish a new population there. How do you expect the genetic diversity of the island turtles to compare to genetic diversity of the mainland turtle population they originated from? Group of answer choices A. Genetic diversity should be similar, since they are the same species. B. Genetic diversity should be higher for the island turtles, because the new environment will produce new alleles. C. Genetic diversity should be lower for the island turtles, since the island turtles represent a small sample of the genetic diversity from the mainland turtles. 2.If the probability of a turtle having a brown shell is 3/4 and the probability of a turtle having a bumpy shell is 1/4, what is the probability of a turtle that has a shell that is both brown andbumpy?

- What do scientists use to apply cladistics? a. homologous traits b. homoplasies c. analogous traits d. monophyletic groupsDog breeders use selective breeding, also called artificial selection, to maintain a closed genetic lineage, and produce offspring with desirable traits. This violates which Hardy-Weinberg condition? a reproduction b no mutation c random mating d no natural selectionIn a cladistic analysis, a systematist groups together organisms that share: derived homologous traits. derived homoplastic traits. ancestral homologous traits. ancestral homoplastic traits. all of the above.
