question 9 of 10
animals from africa and australia have very few similarities and are separated by a great distance. based on this information, which else is likely to be true?
a. they do not share recent common ancestors.
b. they share recent common ancestors that adapted quickly to different conditions.
c. they are closely related but have different traits.
d. they do not share any common ancestors due to the isolation of their habitats.

Explanation:

If animals from two regions (Africa and Australia) have few similarities and are geographically distant, it's likely they don't share recent common ancestors. Option B would imply some similarity (from recent common ancestors), which contradicts the "few similarities" statement. Option C says they're closely related (which would imply more similarity) but have different traits - but the key is the lack of recent commonality. Option D is too extreme as all life shares some ancient common ancestors. So, A is the most logical choice based on evolutionary principles (less similarity and distance suggest no recent common ancestry).

Answer:

A. They do not share recent common ancestors.
