Common Ancestry

Question 5 • AFC AP Biology B5

Which evidence suggests a common ancestor between fungi and animals?

Answer
A
Fungi and animals colonized land around the same time.
B
Fungi and animals are both heterotrophs with mitochondria and no chloroplasts.
C
Both organisms evolved from green algae and have cytoskeletons made of cellulose.
D
Both have membrane-bound organelles, including chloroplast and linear chromosomes.

Explanation

Fungi and animals share key traits: both obtain food as heterotrophs, have mitochondria, and lack chloroplasts. These shared characteristics are evidence of a closer evolutionary relationship and a common ancestor. Choice A describes timing, not shared ancestry, while C and D include incorrect claims about their traits.
