Define natural selection and give Example with detailed explanations.

Natural selection is when animals who are able to survive in their environment flourish, and those animals who aren't die out.

Explanation:

Lets say there were two rival animals, we can call them plantoids 1 and 2. These plantoids were both trying to out-survive each other. The problem is birds loved to eat them, so through evolution plantoids 1 began producing toxins, so when chewed on the bird would be poisoned. For awhile this worked, and the plantoids without it were dying off. Then plantoids 2 created a thorn on their heads, and were able to blend well. This worked well, and sadly for plantoids 1 the birds were able to eat them. The birds went through natural selection and those who were immune to the poison survived. Now these two plantoids are two completely different species, and they were once the same. In the end plantoids 2 survived because they were more adapted to the setting they lived in.
