ANSWER ALL THE QUESTIONS FOR BRAINLIEST

How long ago did the common ancestor of all the organisms on this phylogenetic tree exist?

b. Which two lines diverged 30 million years ago?

c. List all modern descendants of the organism that was alive at the point indicated by the asterisk.

According to Model 1, when did the Giant Panda line diverge from the line that led to modern
bears?

According to Model 1, what animal shares the most recent common ancestor with the Brown
Bear?

In a complete sentence, describe what the branch points and lines in a phylogenetic tree
represent.

Which of the two branches from the common ancestor in Model 1 has the most living
descendants?

6. According to the phylogenetic tree in Model 1, the Red Panda is most closely related to which
animal?

7. Which are more closely related, the Giant Panda and the Red Panda or the Giant Panda and the
Polar Bear? Justify your answer using grammatically correct sentences.

A phylogenetic tree is a diagrmmatic representation of evolutionary relationships in a tree form where branches represent diversification of species.

From the phylogenetic tree shown:

the common ancestor of all the organisms on this phylogenetic tree existed 40 million years ago
the two lines diverged 30 million years ago is the raccoons and red panda and the bears and Model 20
The spectacled bear, sloth bear and sun bear were alive at the point indicated
the Giant Panda line diverged from the line that led to modern bears 20 million years ago
the polar bear shares the most recent common ancestor with the Brown
Bear
The branch points in represents the divergence points and the lines represent timelines
The branch having the bears and giant panda has the most livingdescendants
The red panda is most closely related to the raccoons
The giant panda and polar bear are most closely related

Therefore, the phylogenetic tree shows the evolutionary relationship between bears and pandas.
