Question

Raccoons and red pandas have more similar DNA sequences than red

pandas and giant pandas do. What does that tell scientists?
A. Red pandas and giant pandas share a more recent common
ancestor than red pandas and raccoons.
B. Red pandas and raccoons share a more recent common ancestor
than red pandas and giant pandas.
C. Raccoons descended from red pandas.
D. Red pandas descended from giant pandas.

Answer 1

Answer: B

Step-by-step explanation:

Red pandas and raccoons share a more recent common ancestor.

Answer 2

B. Red pandas and raccoons share a more recent common ancestor

than red pandas and giant pandas.

Step-by-step explanation:

DNA sequencing is finding the sequence of base pairs in an organism's DNA, and it's often used to compare with other organisms. The more base pairs that are the same, the more similar the two organisms are, and this means that they share a more recent common ancestor.

We can't make any conclusions like C and D because we just don't have enough data to conclude that one descended from the other.
