Creationism - A.k.a. intelligent design Came from a philosopher who said “someone” had to make that (watch from sand and ocean on beach story) How could this have happened? 550-560 million years ago was the last time the earth was covered in ice and everything came about after that 1.

Aristotles’ “scala naturae” Lived in about 300 B.C., wrote this book and described every species in  By reading it we can note that there have been no change in these past  d. Flora and fauna of Europe Flora =  plants, fauna =  animals In Europe these were distinct, and there wasn’t a large variety o This was because they couldn’t see the different relationships because  very few species were known B.
