If evolution is true, then why are there so many gaps in the fossil record? Shouldn't there be more fossils that show exactly how evolution occurred? a. All of options help explain the gaps b. The fossil record can be accidentally destroyed by processes like erosion. This can create gaps in the fossil record. c. Evolution does not always occur at a constant rate. If something like heterochrony occurs, the organism may change so much it would appear as if there were a gap between it and close relatives d. The fossil record is biased and may not show many organisms that lack hard body parts e. The fossil record is incomplete because some organisms do not live in environments that promote fossilization (the tend to decay instead of fossilize)

The fossil record provides evidence for evolution. Choose the statements that correctly describe the evidence for evolution provided by the fossil record. For full marks, you must choose all responses that apply. A) All ancestral organisms can be found in the fossil record. B) The fossil record shows the appearance and disappearance of species. This supports the evidence that certain species evolved from ancestral forms (such as whales from a terrestrial ancestor). C) More recent fossils are most similar to species alive today. D) Evidence of mechanisms for change are preserved in the fossil record. E) Older layers of rock appear under newer layers of rock. This allows species to be placed in chronological order in the fossil record.

Why does the presence of extinct forms and transitional features in the fossil record support the pattern component of the theory of evolution by natural selection? a. It supports the hypothesis that individuals change over time. b. It supports the hypothesis that weaker species are eliminated by natural selection. c. It supports the hypothesis that species evolve to become more complex and better adapted over time. d. It supports the hypothesis that species change over time.
The fossil record offers direct evidence for evolution because you can a. see that the types of fossils change over time. b. sometimes find common ancestors. c. trace the ancestry of a particular group. d. trace the biological history of living things. e. All of these are correct.
