Question

What evidence did scientists use to reject the idea that animals like mice and eels come from nonliving things?


A
Examination of animal skeletons under a microscope

B
In-person observations of how these animals reproduce

C
Data on the number of eels and mice in a given space

D
Observations of how quickly these animals arrive in a new area

Answer 1

The most relevant evidence that scientists used to reject the idea that animals like mice and eels come from nonliving things is:

**B. In-person observations of how these animals reproduce.**

This choice reflects the understanding that animals originate from other animals through reproduction, which contradicts the idea of spontaneous generation (the belief that living organisms could arise from nonliving matter).
