Name the deductive process used to test hypotheses based on repeatable observations.
Science
The first name of the author of the scientific work, 'On the Origin of Species'
Charles
This group of animals went through an adaptive radiation after the dinosaurs disappeared.
Mammals
Major drawback of using old DNA for making phylogenetic trees.
It degrades over time.
Term referring to an organism's ability to produce viable offspring.
Ecological Fitness
Define fossil.
ANY evidence of past life
The process by which, under weight, and over long periods of time, the materials which made up the body of the plant or animal may be leached out and replaced with minerals.
Mineralization
The two main characteristics that distinguish mammals from all other animals.
Hair and Mammary Glands
This DNA is only passed on from the mother.
Mitochondrial
The mass extinction at the end of this period resulted in a mammal radiation.
Cretaceous
What term means 'The study of the geographic distribution of species and ecosystems'
Biogeography
A relatively new type of reproduction that serves to increase genetic variation in the offspring
Sexual Reproduction
The name for spontaneous change in DNA.
Mutation
The process beginning with gene duplication and ending with a fully functional gene that performs a different task than the original.
Gene Recruitment
The term to describe a close relationship in which one species benefits, and there is no effect, positive or neutral, on the other species.
Commensalism
Which domain has a membrane-bound nucleus?
Eukarya
The major factor thought to have caused the end of the 'Golden Age of Arthropods'
The term for alleles moving among populations.
Gene Flow
Reproductive isolation that occurs AFTER fertilization.
Postzygotic
Term for the reciprocal changes that occur over time within two or more organisms in a symbiotic relationship.
Coevolution
What organisms first allowed oxygen to become plentiful in earth's atmosphere, allowing more complex organisms to evolve?
Cyanobacteria
Evolution can be defined as a change in the ________ of a population over time.
Genetic makeup
Term for the sharp lowering of a population's gene pool due to events like environmental disasters.
Bottleneck Effect
This concept describes a group of organisms able to breed viable offspring.
Biological Species Concept
DNA segments that resemble functional genes but have lost their protein-coding ability due to accumulated mutations.
Pseudogenes
