The sudden increase in invertebrate fossil diversity
Apparently, and with evidence, these were periods of global catastrophes (for life-forms) where massive numbers of organisms went extinct.

The sudden increase in invertebrate fossil diversity
This is the idea called punctuated equilibria, by paleontologists Stephen Jay Gould and Niles Eldredge. It explains the patterns seen in the fossil record.

Fossil Fuels =)
Fossils are proof of organisms that lived long ago
i think rock and sea is the habitat of fossil becaus these are the remains of organisms
Acid precipitation and fossil fuels are related because, acid rain can harm living organisms and fossil fuels are made from the remains form living organisms.
Gradualism is the theory that evolution occurs slowly and consistently along periods of time. On the other hand, punctuated equilibrium is the theory that evolution does not occurs for long periods of time and then suddenly evolves rapidly in a small short period of time.
