Question

What is allopatric speciation?

Later if my account survives. ​

Answer 1

Explanation:

The early Earth was very different from our Earth today. .These gases created a new type of atmosphere for Earth. The volcanic eruptions spewed gases such as nitrogen, carbon dioxide, hydrogen, and water vapor into the atmosphere—but no free oxygen. Without oxygen, there was still very little that could live on Earth.

Answer 2

Allopatric speciation occurs when reproductive isolation is a direct result of the geographical separation of two (or more) populations through a physical barrier, such as an ocean.
