hereditary changes in groups of living organisms over time The process by which different kinds of living organism ate thought to have developed.

1744-1829 organism developed from lower to higher stages.

use and dis-use:use it or lose it inheritance of acquired charterstics tics

studied galapagos island wrote a book 1859 "on the origin of species by means of natural selection"

SLOW STEADY CHANGE OVER TIME BASED ON ENVIRONMENTAL NEED, EVOLUTION NOT PUNCUATED

PUNCTUATED EQUILIBRIUM

CHANGES OCCUR IN SHORT PERIODS OF TIME, THEN STAY CONSTANT FOR LONG PERIODS.

CHARMING CHARACTERISTICS OF THE SEXES ARE PASSED ON FROM GENERATION TO GENERATION (like bird feather patterns)

alternative form that a single gene may have for particular trait

Diagram with branches that respresnt the hypothesized phylogeny or evolution of species or group: use bioinformatics morphological studies and information from DNA studies

Theory of evolution developed by Darwin based on four ideas ; excess reproduction varitation inheritance and the advantages of specific traits in an environment

anatomically similar structure inherited from a common ancestor

measure of a trait's relative contribution to the following generation

diversification of a species into a number of different species, often over a relatively short time span

structure that has the same function but different construction and was not inherited from a common ancestor

Darwin's term for the selective breeding of organisms selected for certain traits in order to produce offspring having those traits

reduced form of a functional structure that indicates shared ancestry

inherited characteristic of a species that develops over time in response to an environmental factor, enabling the species to survive.

role and position a species has in its environment;

A group of organisms of the same species that occupy the same geographic place at the same time

a large division of Earth's geologic time scale that is further divided into one or more periods.

preserved evidence of an organism, often found in sedimentary rock, that provides evidence of past life.
