What ship was Darwin on?
What was Darwin's job on the ship?
Charles Darwin wrote the book ______________
Where did Darwin see the greatest diversity of species?
How did Darwin know that species had changed over long periods of time?
What is evolution?
What is selective breeding?
How is selective breeding similar to natural selection?
Why do the Galapagos iguana have long claws?
Why do the finches have differently shaped beaks on the different islands?
Evolution occurs through a process called ___________
What is natural selection?
What 3 main factors did Darwin identify that affect natural selection?
How does competition work with natural selection?
Why are only traits that are controlled by genes acted upon by natural selection?
How is DNA used as evidence for evolution?
What is it when many species have similar body structure?
What does it suggest when the embryos of 2 species look very similar for only a short time before looking different?
What chart is used to show the evolutionary relationships between species?
How are the arms of humans and bats homologous structures?
What is needed for a species to change?
What is a scientific theory?
What is it when there are no more of a species alive?
How long did it take Darwin to write his book after the HMS Beagle finished her voyage?
What are 3 types of evidence for evolution?
The HMS Beagle
He was the naturalist
On the Origin of Species
On the Galapagos Islands
He saw evidence in the fossils that species had changed
When species change over time to be better adapted to their environment
When humans choose what traits to breed for. Humans do the selecting for traits
Certain traits are beneficial and are selected for. These traits appear more often in the population
To hold on to the rocks better
Because the beaks adapted to be able to get the food on the island better
Natural Selection
How individuals that are better adapted to the environment are more likely to survive and reproduce
Overpopulation, Variations, and Competition
Organisms that are better adapted survive better
Because only inherited traits can be selected for over time
The fewer differences between the DNA / proteins of 2 species, the more closely they are related
Homologous structures
That the species are not closely related
A branching tree (cladogram)
They have the same arrangement of bones
Isolation or change in environment
A well tested concept that explains a wide variety of explanations
The species is extinct
20 years
Fossils, similarities in early development, and homologous structures
