Speciation and extinction are both art of how living things have evolved yes or no?

The answer is yes.

Explanation:

Speciation and extinction are both related to "evolution."

What is Evolution?

This is defined as "the process of growth and development that organisms have grown or developed from past organisms." This study is very important in living things because it allows scientists and researches to develop medications related to diseases that occur over time.

Evolution is related to Charle's Darwin's "Theory of Natural Selection."

Natural Selection- This refers to the process by which organisms that are well-suited for a particular environment produce more offspring than others.This likelihood of survival leads to the so-called "speciation." This is defined as "the formation of new and distinct species in the course of evolution." On the contrary, the organisms which are not well-suited for a particular environment will be eliminated. This is what you call "extinction."

Therefore, both speciation and extinction are arts of how living things have evolved.
