Question

What do we call the evolution of living organisms on Earth over periods of time?

Answer 1

Answer:

I think A

Changes in populations accumulate over time;

this is called evolution. The fossil record shows us that present day life forms evolved from earlier different life forms. It shows us that the first organisms on Earth were simple bacteria that dominated the Earth for several billion years.

Answer 2

Answer:

A: Biological Evolution

Explanation:

None of these terms actually exist. Evolution is simply called "evolution" and can be applied to multiple things. However, it would be A because organisms aren't geological, as that applies to the Earth itself, the environment isn't changing all at once with a certain organism either, and D honestly on it's own just doesn't make sense at all, so it would be A.
