Question

In Wegener's time, scientists thought that the occurrence of fossils of the same organism in two different, disconnected continents was proof that:
A. there had once been land bridges separating the continents.
B. birds flew between the continents and carried the organisms with them.
C. the weather patterns had changed over time such that some organisms could be blown by the wind from one place to another.
D. there were icebergs in the Atlantic Ocean that could carry organisms from Africa to South America

Answer 1

Answer:

There had once been land bridges separating the continents.

Option: (A)

Explanation:

• Alfred Wegener proposed the 'theory of continental drift' of earth’s land due to ocean.

• In this theory, he mentioned that due to some geographical reason and climate reason the continents got cracked and splits into many parts and drifted way in the water.

• This might be the 'reason for the fossils' of the same organism occurred in different parts of the world.

• Theory was firstly not accepted by the scientist. He was geologist and meteorologist. Transmission of fossils is proof of evolution on earth.
