Question

Please help with these as they are part of 1 question and I am so confused. I really need help like never before and I will highly consider thumbs up but please help asap.

1- If fossil evidence of the most recent common ancestor of A and B (10 million years ago) was found on both sides of the river (that formed 20 million years ago), then the distribution of A and B is best explained by vicariance. ( choose true or false)

2- It is possible that species C will speciate. ( choose true or false)

3- The distribution of the two species-C populations cannot be explained by two totally independent dispersal events by the common ancestor species of A and B. ( choose true or false)

4- B must share a more recent common ancestor with C1 than it does with C2. (choose true or false)

Question 10
A, B, and C are three different island species and all share a common ancestor. Their
ranges are shown in the diagram below. Note that A and B are on a separate island
from species C. Species A andB are isolated from one another by a river. There are
two populations of species C (C1 and C2) that are isolated from one another by a
mountain range.

Is the following statement consistent with the data presented in the diagram, above?
Choose True for yes, the statement is consistent with the diagram.
