a principle that states "slow changes over a long period of time.'
What is gradualism?

This naturalist considered how organisms could evolve through mechanisms of competetion.
Who is Erasmus Darwin?

Name three pieces of evidence that support evolution.
What is homologous structures, vestigial structures, DNA/ATP,embryological similarities, fossils, analogous structures?
100
the ability for a trait to be passed down from generation to generation.
What is heritability?
100
Darwin saw populations of various species that seemed well-suited to their environment. What did this suggest?
What is the species can adapt to their environment?
200
Traces of organisms that existed in the past
What is fossils?
200
Presented evolution as occuring due to environmental change over long periods of time.
Who is Lamark?
200
Which piece of evidence does NOT support a common ancestory?
What is analogous structures?
200
this is a mechanism by which individuals that have inherited beneficial adaptation produce more offspring on average than do other individuals
What is natural selection?
200
Charles Darwin looked up to this relative scientist, who in fact helped Darwin form his evolutionist ideas.
Who is E. Darwin (gpa)
300
the process of biological change by which descendents come to differ from their ancestors.
What is evolution?

What did Carl Linneaus do?
What is developed a classification system for all types of organisms?

A whale and a mole both have the same arrangement of bones in their hands/flippers. A whale uses his flipper for swimming--a mole uses his hands for digging and walking. Do you think the whale and the mole are homologous or analogous? Do they have a common ancestor?
What is homologous, yes!
300
The process by which humans change a species by breeding it for certain traits.
What is artificial selection?
300
What are the two points that most scientists agree on about the Earth's orgin?
What is the Earth is billions of years old and the conditions on Earth were very different from those today?
400
States that natural disasters, such as floods and volcanic erruptions, have happened often during the Earth's history.
What is catastrophism?
400
Who came up with the theory of uniformitarianism?
Who is Charles Lyell?

Why do snakes have pelvic bones when they do not use them?
What is they inherited this characteristic from an ancestor who DID need those bones?
400
Causes variation with in a population.
What is Mutations in DNA?
400
This is the measure of the ability to survive and produce more offspring realtive to other members of the population in a given environment.
What is fitness?
500
States the geologic processes that shape Earth are uniform through time
What is uniformitarianism?
500
Who noticed that some animals may be able to adapt to their environment?
Who is Charles Darwin?

A dolphin is a mammal....a shark is a fish. However, they both have very similar body's and fins. Why? What are these structures called? What is this evolution called?
What is becasue they have similar environments. anaglogous structures. Convergent evolution.
500
What does geographic and reproductive isolation result in?
What is speciation?
500
Name 2 of the 4 principles that Darwin's theory of evolution rests up on.
What is 1) more offspring are produced than possibly can survive. 2) variation exists among the offspring. 3) Organisms must comete to survive and reproduce. 4) the ones best suited to the environment will survive and pass these traits on to their offspring.
