Inherited trait that helps an organism survive
What is an adaptation?
100
Comparative anatomy, comparing embryos, and DNA evidence all support this theory.
What is the theory of evolution?
100
When an organism produces more offspring than can survive to adulthood and reproduce.
What is over-reproduce?
100
Theory of how the continents move
What is plate tectonics?
100
Dodo bird, Steller's Sea Cow, Tasmainian Wolf
What are extinct animals?
200
Slight random changes/mutations in this cause the traits of an animal to change
What is genes/alleles/DNA?
200
These two embryos looked the most similar when developing on the short video we watched last Friday.
What are pig and human?
200
Random variations in traits among individuals in a population of a species.
What is variation or genetic variation?
200
4.6 billion years old
What is how old the earth is?
200
Animals that fail to adapt to their environment or are over exploited and all killed by humans
What is extinct?
300
Random mutations make an animal better suited to survive in this
What is it's habitat?
300
This is the common hereditary material all organisms share
What is DNA?
300
When an animal environment changes and causes favorable changes in traits (adaptations) to be passed on.
What is favorable traits are selected?
300
The two types of dating that paleontologists use to find out how old rocks are.
What is absolute and relative dating?
300
Animals that have this are less likely to go extinct?
What is genetic variation?
400
Random changes in a an animal's can change how an animal (name 3) and makes it better able to survive in its environment.
What is movement, protection, or feeding?
400
The study of anatomical similarities and differences among species
What is comparative anatomy?
400
A successful organism may pass its traits to its offspring through this.
What are traits accumulate?
400
Largest Mass extinction in the world happened during this period
What is the Permian?
400
Loss of habitat, commercial farming, and developement
What is human causes of animal extinction?
500
Darwin noticed particular adaptations in finches on the Galapagos islands that differentiated each species primarily by what trait?
What are their beaks?
500
These provide a historical sequence of life on earth
What is the fossil record?
500
Predators, diseases, food supply, and climate
What are environmental variables that affect the size of a population?
500
These are the four eras of the geological time scale
Cenozoic-->Mesozoic-->Paleozoic-->Precambrian
500
This is thought to be the cause of the dinosaurs extinction during the Cretaceous-Tertiary Mass extinction
