Question

which best describes evolutionary theory?○ it is based on the idea that all life is related.○ it states that organisms have become less complex over time.○ it is not supported by observation or experimentation.○ it has been disproved several times since it was first proposed.

Explanation:

La teoría evolutiva se basa en el principio de que todos los seres vivos comparten un ancestro común, por lo que toda la vida está relacionada. Las otras opciones son incorrectas: la evolución no postula una disminución de la complejidad, sí está respaldada por observaciones y experimentos, y no ha sido refutada.

Answer:

A. It is based on the idea that all life is related.
