Row 1, Col 1 What is the same species? Organisms that can mate with one another and produce fertile offspring

1,2 The preserved remains or traces of organisms that lived in the past. What is a fossil?

1,3 The length of time Darwin thought it took for species to evolve. What is slowly?

1,4 Remains of a once living organisms that can be used as evidence of a common ancestor. What are fossils?

2,1 Control traits What are genes?

2,2 A fossil formed when minerals replace all or part of an organism What is a petrified fossil?

2,3 The process by which individuals that are better adapted to their environment are more likely to survive and reproduce. What is natural selection?

2,4 Similar structures that are evidence that two organisms share a common ancestor. What are homologous structures?

3,1 What is a mutation? Any change in a gene or chromosome

3,2 Method to compare the ages of two fossils based on the layer of rock in which it was found What is relative dating?

3,3 The location of most of Darwin’s observations which lead to his Theory of evolution What are the Galapagos Islands?

3,4 Fossils, similarities in early development, similarities in body structure, DNA, and protein structure. What are evidence of a common ancestor?

4,1 A trait that helps an organism survive and reproduce What is an adaptation?

4,2 The length of time it would take for 30g of an element to decay to 7.5g when the half life is 150 years. What is 300 years?

4,3 Darwin studied this in order to develop his theory of evolution. What is selective breeding?

4,4 Scientists have found fossils of whale-like creatures that had legs. What is evidence that the ancestors of whales once walked on land?

5,1 Differences between members of the same species What are variations?

5,2 The length of time it would take for 440g of an element to decay to 13.75g when the half life is 127 years. What is 635 years?

5,3 The beaks of finches were different on different islands according to what food was available. What are Darwin’s observations?

5,4 Overproduction, Variations, and Competition. What are 3 causes of natural selection?
