Fossil evidence indicates that the following events occurred in what sequence, from earliest to most recent? 1. protostomes invade terrestrial environments. 2. cambrian explosion occurs. 3. deuterostomes invade terrestrial environments. 4. vertebrates become top predators in the seas.

Let's complete the question by writing the sequence, from earliest to most recent options

a. 2 → 1 → 3 → 4

b. 2 → 4 → 3 → 1

c. 2 → 3 → 1 → 4

d. 2 → 1 → 4 → 3

e. 2 → 4 → 1 → 3

It's surely going to be e.

e. 2 → 4 → 1 → 3

2. Cambrian explosion occurs.

4. Vertebrates become top predators in the seas.

1. Protostomes invade terrestrial environments.

3. Deuterostomes invade terrestrial environments.

Got it!

answer: that would be cheating
