Biology essay revision

I’m working on a English exercise and need support.

Attached is a pdf of my original essay. The essay is good however there are a few revisions that must be made. Below I will attach the teachers comment. Tutors job is to make the revisions necessary for a complete grade. Only a few minor changes nothing major.

Teachers comments: This is a strong start. A few things need revision: (1) Your examples of natural selection include wording that leave the wrong impression about natural selection, making it sound like individuals need to change themselves in order to adapt (see your first misconception). (2) Your discussion of reinforcement is a little confused at the end and I’m not really sure what you mean to say. Explain a little more and/or discuss with me if need be.
