Question

The evidence that species change gradually over time is found in

Answer 1

Are there any answer choices?

Answer 2

old question, but will respond so this can be closed

answer choices
-Lamark's publications
-the ecological species concept
-Darwin’s journals
-the fossil record

Answer 3

going through the choices one by one

- Lamark's publications --> false, as his primary argument was that individual animals adapted to their surroundings
-the ecological species concept ---> false, as this is simply the idea that species should be defined based on their niches
- Darwin's journals ---> false. this is a good guess, though. Darwin observed differences in species based on their enviornment, and developed the theory of natural selection (organisms w/ favorable traits are more likely to pass on their genes). however, this by itself is not good evidence of species changing over time

leaving us with: -the fossil record, which is physical evidence that species change over time. you can observe fossils, date them, and observe how they change over time.
