Studied fossils
|
Georges Cuvier
|
|
|
Realized that lower layers in strata had older fossils
|
Georges Cuvier
|
|
|
Realized that lower layers more dissimilar to modern species
|
Georges Cuvier
|
|
|
Studied geology
|
Charles Lyell
|
|
|
Came up with The Theory of Uniformity
|
Charles Lyell
|
|
|
What is The Theory of Uniformity
|
Geologic processes have not changed throughout earth's history
|

|
The Theory of Uniformity
|
|
|
Proposed a theory that acquired charateristics could be passed on to offspring
|
Jean Lamarck
|
|
|
What is Darwin's Theory
|
A population can change over time when individuals differ in one or more heritable traits that are responsible for differences in the ability to survive and reproduce
|
|
|
Who theorized a population can change over time when individuals differ in one or more heritable traits that are responsible for differences in the ability to survive and reproduce
|
Charles Darwin
|
|
|
Theorized along with Darwin
|
Alfred Wallace
|
|
|
What make up Darwin's Theory
|
1. Variation exists in living organisms
2. More of each kind of organism is produced that can possibly survive 3. Competition results 4. The fittest survive 5. These survivors live longer, reproduce more, and pass their successful or fit characteristics on to their offspring so that in the next generation there are more individuals with the successful varitation or characteristic |
|
|
Evidence that 1. Variation exists in living organisms
|
a) all populations have a wide variety of characteristics
b) one of these traits may be beneficial in an organisms survival |
|
|
Evidence for 3. Competition results
|
because there are not enough resources to support reproductive capability
|
|
|
Evidence for 4. The fittest survive
|
They are able to compete better for resources
|
|
|
Argued that as population size increases, resources dwindle, the struggle to live intensifies & conflicts
|
Thomas Malthus
|
|
|
A difference in the survival & reproductive success of different phenotypes
|
natural selection
|
|
|
What is natural selection?
|
a difference in the survival & reproductive success of different phenotypes
|
|
|
Acts directly on phenotypes & indirectly on genotypes
|
Natural selection
|
|
|
What is evolution?
|
Genetic change in a line of descent through successive generations
|
|
|
Genetic change in a line of descent through successive generations
|
evolution

|
|
Results of Artificial Selection
|
extremes in size; extremes in form
|
|
|
What is Comparative Morphology?
|
study of similarities & differences in body plans of major groups
|
|
|
Study of similarities & differences in body plans of major groups
|
Comparative Morphology
|
|
|
What is Comparative Embryology?
|
each animal or plan proceeds through a series of changes in form; similarities in these stages may be clues to evolutionary relationships
