Change in a species over time
What is evolution?
Group of organisms so similar to one another that they can breed and produce fertile offspring
What is a species?
Allow evolution to occur because they introduce new traits
What is DNA mutations?
Charles Darwin's theory
What is theory of evolution?
Geographical distribution of organisms
What is biogeography?
Evolution of a new species
What is speciation?
An ancestor (early type of organism) that two or more descendants have in common
What is a common ancestor?
Permanent change in the structure of a gene
What is a mutation?
Change in a body part size, shape or overall body design in response to the environment
What is structural adaptation?
Remains of organisms that tell the history of how the species evolved
What is fossil record?
Mutation that is beneficial for survival
What is Adaptation?
A substance that is necessary to individuals exists in a smaller quantity than needed
What is a limited resource?
Transfer of genes from one population to another, increases genetic variation
What is gene flow?
Change in the way an organism behaves
What is behavioral adaptation?
Comparisons of different organisms anatomy in terms of structure and function
What is comparative anatomy?
All of the individuals of a species that live in the same area
What is population?
Transfer of genes from one population to another
What is gene flow?
Random event that results in part of a population being removed, regardless of adaptations
What is genetic drift?
Change in the internal workings of an organism in response to the environment
What is physiological adaptation?
The study of how an embryo develops
What is embryology?
The success of individuals who have beneficial traits in their environment to survive and reproduce
What is natural selection?
The alteration of allelic frequencies by chance events
What is genetic drift?
Father of Evolution
Who is Charles Darwin?
Four major points of the theory of evolution
What is variation in a population, organisms compete for limited resources, organisms produce more offspring than expected to survive, those with beneficial adaptations survive and reproduce?
Comparison of different organisms' DNA or protein sequence to determine relatedness
What is molecular biology?
