Influences to Darwin

Question: Name the four humans influences to Darwin (only the names)
Answer: Wallace, Hutton and Lyle, Lamarc, Malthus

Question: How do fossils provide evidence that support evolution?
Answer: "Snap shot frozen in time" that shows the changes in animals

Answer: -Economist.
-Observed people in London dying off from disease, struggle for existence and survival of the fittest

-ORGANISMS DO CHANGE

Answer: On the origin of species
Wallace

Evidence of Evolution

Question: How does comparative embryology help support evolution?
Answer: -homologous structures
-evidence of common ancestry

Question: What is the significance of comparative biochemistry in the world of evolution?
Answer: -shows genetic similarities and differences
-can help with common ancestry

Question: The wings of a kiwi are too small to be of any use in flight, this is an example of
Answer: vestigial structures

Question: Describe why homologous structures provide only a RESOURCE of evolution but cannot be a strict EVIDENCE of evolution
Answer: -it is a good explanation of biological data for evolution but cannot just use this as a complete explanation

Question: What is the significant of transitional fossils? What is an ancestral trait and what is a derived trait in terms of the organisms we discussed in class?
Answer: -frozen in time snap shot of an organism that is in the "middle of evolving"
ancestral=reptilian features=teeth, claws, tail bone
derived= feathers

Galapagos

Question: What are the types of birds, and two tortoises that we studied?
Answer: Finches
Saddle-backed tortoise
Domed tortoise

Question: How many relatives did the Finches originate from?
Answer: 2

Question: Which tortoise is smaller and why?
Answer: Saddle-backed
better for a hotter environment with little water and less shade
uses less energy

Question: Describe the different physical anatomy between the saddle-backed and domed tortoise
Answer: saddle-backed=two humps and a wide opening on the neck to let the heat out, able to reach and stretch neck to get cacti leaves high up
domed=shaped to keep heat in and moisture out

Question: Describe in terms of the Finches lab the idea of natural selection
Answer: -those finches that are able to survive in a particular environment were able to do so bc they already had a varying trait that was better suited for the environment
-this leaves room for many finches with different beak to live in different environments

Question: What is the biological term that describes the cumulative change in groups of organisms through time?
Answer: Evolution

Question: What is the biological term for this definition: some competitors in the struggle for existence would be better equipped for survival than others. Those less equipped would die....
Answer: Natural Selection

Question: Why did the Inuit population not have any cases of heart disease despite the fact that they ate 70% fat?
Answer: Those that had heart disease died so they were unable to reproduce
Those that did not get heart disease, reproduced and passed on the varying trait of not getting heart disease from eating fatty foods and thus contributed to the zero cases of heart disease in a population

Question: Darwin was what type of scientist? How do these scientist go about their scientific findings?
Answer: Naturalist
uses the observations to make conclusions

Question: Provide one example for
-homologous structures
-analogous structures
-vestigial structures
Answer: see what they say.....
