Natural selection Flashcards
the fundamental and distinctive characteristics or qualities of someone or something, especially when regarded as unchangeable
DNA
a compound consisting of a nucleoside linked to a phosphate group
Nucleotide
They built a model of DNA
Watson and Crick
the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA
mutations
a change or the process of change by which an organism or species becomes better suited to its environment
Adaptation
a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding
Species
the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth
evolution
he remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock
Fossils
A term used by paleontologists to refer to the total number of fossils that have been discovered, as well as to the information derived from them
Fossil record
was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution
Charles Darwin
a distinguishing quality or characteristic, typically one belonging to a person
Trait
the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together
Selective breeding
the process where by organisms better adapted to their environment tend to survive and produce more offspring
Natural Selection
the generation time is the average time between two consecutive generations in the lineages of a population
Generation Time
the formation of new and distinct species in the course of evolution
Speciation
