- Why is it important to study evolution? Explain in three paragraphs.arrow_forward1. a) How does this experiment demonstrate the definition of evolution? b) Fitness of organisms is a function of the environment (that is, organisms best fit to the local environmental conditions leave more surviving offspring).

- What is the difference between an adaption and a mutation concerning evolution?arrow_forwardCharles Darwin came up with several original ideas in his 1859 publication The Origin of Species. Some of these ideas are now generally accepted, some are still hypothetical, some are conditional, and some are now believed to be incorrect. List several of his ideas (including at least one from each category), and explain why each of these ideas are either: (1) considered to be essentially correct, (2) considered to be hypothetical, (3) considered to be conditionally correct, or (4) considered to be incorrect.arrow_forwardThe following illustrations represent two different patterns of evolution.
