The next few questions refer to the following evolutionary tree, whose horizontal axis represents time (present time is on the far right) and whose vertical axis represents morphological change. W Present V X Y Z Which species is most closely related to species W? Identify where species V and Z have a common ancestor. Which of these five species originated earliest and appeared suddenly in the fossil record?

A Moving to another question will save this response. Question 4 А. Identify the most accurate statement about the phylogeny below. Assume species D is an outgroup. С. D. O a. The color on the tail fins of species B and C is best described as the result of evolutionary reversal. O b. The dorsal fin coloration seen in species A and C is likely due to convergent evolution. Oc. The presences of spots on species A and C is best explained by homology. O d. The color of the pectoral and pelvic fins in species A, B, and D is best explained by homoplasy. AMoving to another question will save this response. A. B.

Just need help filling out this multi-part question.

PLEASE TELL THE ANSWER IN SHORT LINES AND PLEASEEE DO THIS FASTT

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)

Explain your answer in some depth and avoid just saying "It is A" or It is B. Defend your answer and explain why you choice that answer choice.    Question: Domestic dogs would least likely meet the definition of a single species using which concept?

You are a mad scientist tasked with the evil job of designing a novel species. This species will be introduced to an ecosystem and must cause as much damage as possible. What abilities and characteristics will you give this species to make it successful? Be sure to explain why you choose each aspect. Explain your choice in 3-5 sentences.
