Need some help writing a scientific argument.

Some 8th graders were discussing a biology lesson on the Stickleback Fish population. Scientists have observed that the Stickleback population today has less armor and is faster than the population generations ago. Why?

What caused the Stickleback population to have less armor and be faster?

Here is what each student thinks:

Diana: The sticklebacks have less armor so they can escape predators.
Ruben: The sticklebacks have less armor so they can catch prey.


Write a scientific argument to support the student you agree with. Use EVIDENCE, VOCABULARY, and be specific with the CAUSE-AND-EFFECT relationship. Cite at least 3 pieces of evidence to support your argument.
