Science - Natural Selection Vocabulary

Adaptation - Structural

physical appearance that an organism has to help survive in environment

Adaptation - Behavioral

sometimes species changes behavior to help survive in environments

Artificial Selection

traits that are selected by humans - don’t always help their survival - traits from parents - changes over generations

Charles Darwin

Naturalist who noticed diversity of life (including fossils) on his voyages in the Galopagos

Diversity

different alleles present in a species population

evolution

process by which modern organisms have descended from ancient organisms

fitness

organism that is “fit” will be able to SURVIVE AND REPRODUCE

Genotype

genetic code of an organism - alleles or variations of traits

inheritance

passing of genetic qualities by transmission parent to offspring

mutations

any change in DNA of a gene or chromosome which can be inherited from parents

inherited when passed from parent to offspring during reproduction

could be harmful, neutral, beneficial - leads to evolution

natural selection

mechism of evolution

organisms that are adapted are more likely to pass genes for success

cause species to change over time

offspring

product of reproduction, progeny, new generation

phenotype

physical appearance or features of an organism

population

inhabitants of a reproducing species within a given ecosystem

species

a grouping of organisms that can interbreed and are reproductively isolated from other such groups
