Give a Darwinian explanation of how cheetahs evolved to become faster. Your explanation is how natural selection works using Cheetahs as an example. Be sure to include andexplain the ideas of differential reproductive success and descent with modification. (You do not need to mention the formation of new species.)
Match the term that best describes the different groups of primates.
a)Gibbons and Siamangs
b)Gorillas
c)Bonobos
d)Lemurs and Lorises
e)Marmosets
CHOOSE
Small bodied apes that are mostly brachiators
type of new world monkey with the ancestral trait of retained claws
largest primates that are primarily vegetarian
morphologically similar to chimpanzees; copulate throught female estrus cycle
the primates with the most ancestral/ primitive traits
What data would suggest that a species evolutionary history includes sexual selection as a mechanism that helped shape the species?
If males and females are significantly different from each other (sexual dimporphism)
If males and females form different social groups (i.e. herds are formed from either males or females but not both)
If some males reproduce with multiple females while other males do not reproduce
If males engage in "risky" behavior

- 13) The model shows the process of evolution at work in a population of aphids with varying amounts of pesticide resistance. Select ALL of the requirements for evolution to occur. A) Sexual reproduction must occur. B) The final population is purely random. C) Genetic variation must exist in the population. D) Those with the highest pesticide resistance reproduced. E) Only those with the highest pesticide resistance level survived exposure to the pesticide. Not Gradedarrow_forwardIn social insects, colonies often consist of a queen and workers. The workers are typicallydaughters of the queen. The queen is the only reproductive individual—the workers aresterile. a) According to Hamiton’s rule, what is the maximum ratio of cost to benefit (C/B) for theworkers in order for this system to evolve?b) Some colonies of ants have multiple queens, which can be related to different degrees.Imagine that two sisters start a colony, so that they are the mother or aunt to allworkers. What is the maximum ratio of cost to benefit (C/B) for the workers to sacrificefor their aunts?arrow_forwardAssume that a lineage of rainbow trout accumulates mutations over time that make the trout a uniform dark brown with orange spots and produce a dorsal fin shape that is very different from all other rainbow trouts. This group of rainbow trouts also has lips that are twice the size of other rainbows and they have a much narrower body. How do we know when the natural selection of such characteristics results in a new species of fish?arrow_forward
- 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?* OAllopatricarrow_forwardHow might an evolutionary biologist explain why a species of salamander becomes blind after colonizing a cave? Group of answer choices Members of the ancestral population that colonized the cave differed in their ability to see. If maintaining the ability to see in the cave was a waste of energy, blind salamanders might actually have more offspring than those who could see. It is possible that in the cave there is a source of pollution that increases the mutation rate for a gene that makes salamanders blind. Over time, due to exposure to this chemical, the membersof the population lose their sight. There is no way to explain this in terms of natural selection. The members of this salamander species no longer needed to use their eyes. Over time, due to lack of use, they lost the ability to see.arrow_forwardn which situation would it make sense to use the phylogenetic species concept?
