What was the biological evidence that the continents used to be together and have since drifted apart? (check all that apply)

Question

a
Several species seem to be strangely similar even though they are on far away different continents, meaning at one point they must have been on the same one at some point
b
Multiple species have dietary habits that can only be satisfied on specific continents, meaning they must have consumed materials on the same place once
c
Fossil records show two of the same species existing on two different continents, which could only be possible if they once lived in the same place
d
The vestigial organs of certain species can only be explained if they evolved in the same location

Answer 1

The options that provide biological evidence that the continents used to be together and have since drifted apart are:

a - Several species seem to be strangely similar even though they are on far away different continents, meaning at one point they must have been on the same one at some point.

c - Fossil records show two of the same species existing on two different continents, which could only be possible if they once lived in the same place.

These two pieces of evidence support the idea of continental drift and the concept of a supercontinent, as they highlight the similarities in species and fossil records that suggest a historical connection between continents.

Option b is less relevant, as dietary habits do not directly imply continental drift. Similarly, while option d about vestigial organs could hint at a shared evolutionary history, it is not as direct a piece of evidence for continental drift as the similarity of species and fossil records.
