In terms of genetics, metabolism, and ecological relationships, describe the process of human co-evolution with microbiome species and at least 1 example in which they accelerated our evolution. Emphasize microbial partnerships and mechanisms with our general physiology, immune system, and nervous system.

Which of the following statements is true about the theory of evolution?

The focus of the theory of evolution is to explain the origins of life.

According to the theory of evolution, life evolved entirely randomly.

The focus of the theory of evolution is to explain how life diversified from the first living cells.

According the theory of evolution, only the strongest and toughest can survive.

Which of the following best explains our current understanding of microevolution?

Neither microevolution nor macroevolution can be observed within a human lifespan?

Microevolution is the gradual change of the genetic makeup (allele frequency) of a population over time.

Microevolution and macroevolution occur by very different mechanisms

Microevolution is the evolution of small organisms; macroevolution is the evolution of large organisms.

The Irish elk is a giant species of deer that went extinct about 5,000 B.C. They are well-known for their extremely large antlers (12 feet wide) in males. The antlers likely played some role in protection against predators, but another possible cause for their large size could be

blending genetics

sexual selection

spontaneous generation

inheritance of acquired characteristics

Cross River gorilla is listed as critically endangered species. With only 35 of these gorillas in the world, they are at risk of extinction largely due to poaching and loss to diseases such as Ebola. Genetic studies of the remaining gorillas show very little variability, because several alleles were likely lost due to ______.

		genetic drift
		gene flow
		increased rate of spontaneous mutations
		adaptive radiation

3. Some Caminalcules went extinct without leaving descendents. In the real world, what intrinsic factors (i.e., related to an organismâs basic reproductive biology, population biology, ecological niche, etc.) or extrinsic factors (e.g., ecological/environmental factors) might increase or decrease the probability of a species going extinct? PLEASE DO NOT REFER TO HUMAN-CAUSED EXTINCTIONS IN YOUR ANSWER.

4. Find two additional examples of convergent evolution among the modern-day Caminalcules. This means finding cases where two or more species have a similar characteristic that evolved

independently in each lineage. The wing of bats, birds and bees is an example of

convergence since the three groups did not inherit the characteristic from their common

ancestor. Write your answers in complete sentences (e.g.,âSpecies x and y both have ____

but their most recent common ancestor, z, did notâ). List two additional real-world examples

of convergent evolution (ones that we have not already talked about in class) and discuss

what might have caused the convergence.

5. a. Describe two examples of vestigial structures that you can find among the

Caminalcules. These are structures that have been reduced to the point that they are

virtually useless. Ear muscles and the tailbones are examples of vestigial structures in our

own species.

b. Explain how vestigial structures provide clues about a speciesâ evolutionary past.

Illustrate your argument with vestigial structures found in humans or other real species.

Kindly answer question 3 to 5 thank you.
