This week we learned about evolution, common ancestry and the origins of life. We looked at two different hypothesis on the origin of life, one supported the replication-first theory and the other explained the metabolism-first hypothesis. We used these worksheets to learn about the differences in the two theories.
The chapter 19 reading was about evolution, variation and natural selection.
It included these tree-shaped diagrams that show how different species come from common ancestors. What was that common ancestor? I am curious how people have reacted to these ideas of evolution over the years and why some people still don’t believe in it.
