Evolution Notes

What is a theory? An explanation of multiple phenomena based on proven hypotheses Can be repeatedly tested Have withstood lots of scrutiny Examples of scientific theories: Cell Theory Heliocentric Theory Theory of Relativity

How is a theory different from a law? Laws explain how things will act under SPECIFIC CONDITIONS Theories are broader – explaining how nature works, etc. A theory will always remain a theory and a law will always remain a law

So, what is evolution? The theory of evolution states that all the lifeforms on earth share a common ancestor as a result of variation and selection over a very long time (currently thought to be around 4 billion years). Evolution as a process is the changing and development of new species over time.

Do we have evidence of evolution? Yes, a lot of it! We have case studies of species evolving over time, as well as evidence that species have evolved in the past before humans were here to study it. https://www.youtube.com/watch?v=LyRA807djLc
