Evolution
The process of biological change by which descendants come to differ from their ancestors.
The differences in the physical traits among individuals in a group of organisms.
All individuals of a species that live in an area.
Biogeography
The study of the distribution of organisms around the world.
Paleontology
the study of fossils or extinct organisms
Species
A group of organisms that can reproduce and have fertile offspring.
Galapagos tortoises
Darwin studied the different species.
Fitness
A measure of the ability to survive and reproduce.
Homologous structure
Forelimbs of humans, bats, and moles.
Draw a Picture.
A picture of the human evolution.
Linnaeus
Came up with organize and name all of the different known types of organisms, or species.
A feature that allows an organism to better survive in its environment.
Individuals of a species differ due to genetic variation.
Analogous structure
Bird wings and butterfly wings
Write.
Write all of the fields of science used in the basic principles of evolution.
Gradualism
The idea that landforms were shaped by very slow changes over a long period of time, and not by natural disasters.
Darwin
Spent 20 years researching biological evolution.
Overproduction
Organisms have more offspring than can survive.
Vestigal structure
pelvic bones in whales
Nothing in Biology makes sense except in the light of evolution.
Catastrophism
The idea that past natural disasters like floods and volcanic eruptions-shaped landforms, and caused species to become extinct in the process.
Earthquake
Saw that land had been underwater and got shifted up above the sea level.
Adaptation
Some individuals have certain variations that allow them to survive better than other individuals in their environment.
4 lines of evidence
fossils, geography, embryology, and anatomy
Natural Selection
A mechanism for evolution.
