Clownfish lay between 100 and 1,000 eggs at a time Clownfish lay between 100 and 1,000 eggs at a time. Explain why the reef is not overpopulated by clownfish. Use the terms: natural selection, overproduction, competition, variations, and successful reproduction
Sect 1- Change Over Time Adaptation Species Evolution
Evidence of Changes Over Time Fossils What type of rocks? Where do you find the newest fossils? Oldest? Extinction Relative dating What evidence does the fossil record show?
Evidence of Ancestry and Evolution What bones show whales are related to land mammals? DNA Embryology Homologous structures Fossils
How Does Evolution Happen? Natural Selection -overproduction -variations -competition -successful reproduction ***Finches! ***Peppered Moths! What causes variations? How is genetics related to evolution? When do 2 populations evolve into 2 different species?
