What is biological evolution? - Answer-Heritable change in a population across many generations. What is the difference between microevolution and macroevolution? - Answer-Microevolution is on a small scale. It is a change in a single gene. Macroevolution is on a large scale and results in the formation of a new species. What is a scientific theory (definition)? - Answer-A well-tested concept that explains a wide range of observations. What is catastrophism? - Answer-The idea presented by ...
