Evidence of Evolution

1. A evidence of evolution could be crossbreeding plants. I think it is a good example because you can change how plants look and what they produce over an amount of time. When you are cross breeding plants over an amount of time plants reproduce odd plants and then you take that plant and make it reproduce then they look like that odd plant. Then you have a different kind of species of plants.

2. Another type of evolution is pesticide resistance in insect species. An example of this is if you have a field of grass hoppers and the are eating your cops and you spray a chemical that kills them, but they all don't die and then you keep spraying them with it, they will eventual grow immune to that chemical. Then you will have to spray a different chemical.

3. DNA can also be an evidence of evolution. When a person is born they have there DNA and it is a mixture of there moms and dads. Every person is different so it makes everyones DNA different. So every day it is changing somewhere around the world and everyone has different DNA.

  1. Your writing was very good, but maybe you could label them and then talk about what it means :))
