3. Some Caminalcules went extinct without leaving descendents. In the real world

Question

3. Some Caminalcules went extinct without leaving descendents. In the real world, what intrinsic factors (i.e., related to an organism’s 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.,“Species x and y both have ____

but their most recent common ancestor, z, did not”). 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 species’ evolutionary past.

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

Kindly answer question 3 to 5 thank you.

The probable reasons behind the extinction of some Caminalcules are:

5. The two vestigial structures of Caminalcules were ear muscles and tail bones.
