Biological Evidence and the Fossil Record Answers

Which of these statements best sums up evolution?

Biology shows us the fossil record and comparative anatomies. Chemistry shows us that organic molecules can come from inorganic matter. Geology shows us that organisms that used to live together are found on separate continents due to continental drift. Which fields of science provide evidence for evolution?

Which kind of evidence studies mineralized bone, footprints, or organisms trapped in amber to determine common ancestry?

Dogs have a reduced nonfunctional digit on their paws known as a dewclaw. What is this an example of?

A scientist makes the argument that she has found DNA evidence that shows that evolution does not exist. What would her evidence have to show for her to be correct?

Whales have what seem like remnants of a pelvis and femur, as shown here.What are these structures an example of?

Marsupials are found in North America and Australia, but they would not have been able to swim across the ocean. According to scientists, how did this group of organisms come to live on two separate continents?

Which lists the correct order of evolutionary history?

Wisdom teeth are the third and final set of human molars that come in during the late teens or early twenties. In some cases, these teeth come in without problems, but they often have to be removed due to misalignment in the jaw, as shown below. Removal of the teeth does not cause any long-term complications in regard to eating.Which type of anatomic structure are wisdom teeth?

Siblings have similar traits because they inherit those traits from a common ancestor. How is this similar to some evidence for evolution?
