Due right how did wegener explain why fossils of land animals were found on continents that are across oceans from one another? animals evolved separately on each continent. land bridges existed between the continents. animals swam across the ocean to new continents. continents were once one landmass and have drifted apart.

Option D, Continents were once one landmass and have drifted apart.

Explanation:

The continental Drift Theory was proposed by Alfred Wegener . In this theory he stated that the different continents which are existing today were once the part of same land mass. This large piece of land mass drifted over time and got separated into small land masses (or continents).

He then quoted the case of Pangaea,  a super continent existing during the period of late Paleozoic and early Mesozoic eras which began to  break apart about 175 million years ago.

Being from same land mass, all the continents have similar land animal fossil

hence, option D is correct

the answer is "a.) well–developed vascular system."

explanation:

the answer would be knowledge about cars!
