HELP! 50 POINTS!! WRITE IN YOUR OWN WORDS!

<u>Evolution is sometimes a controversial:</u>

Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.

I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.

I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.

Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.
