Intro to Evolution - Darwin's theory

Chapter 16 Miller and Levine Biology
change in a kind of organism over time; process by which modern organisms have descended from ancient organisms
the preserved remains or traces of an organism that lived in the past
artificial selection
selective breeding of domesticated plants and animals to produce offspring with desired genetic traits
inherited characteristic that improves an organism's ability to survive and reproduce in a particular environment
a measure of an organism's ability to survive and produce offspring relative to other members of a population
natural selection
the principle that, among the range of inherited trait variations, those that lead to increased reproduction and survival will most likely be passed on to succeeding generations
dealing with the geographical distribution of animals and plants
homologous structure
structures that have different mature forms in different organisms but develop from the same embryonic tissues
analogous structure
structures that do not have a common evolutionary origin but are similar in function (examples bird wing, and a bee wing)
vestigial structure
remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species
naturalist who formulated a theory of evolution by natural selection, wrote the book "Origin of the Species" (1809-1882)
naturalist who proposed that evolution resulted from the inheritance of acquired characteristics (1744-1829)
geologist who is considered the 'father of uniformitarianism' - the belief that the earth was old, and changed slowly over time
said that earth is shaped by geological forces over long periods of time- thus earth is millions years old
said human population cannot continue to increase exponentially; consequences would include war, famine & disease
English naturalist who formulated a concept of evolution that resembled Charles Darwin's (1823-1913)
a situation in which too many organisms compete for the natural resources in an area
the struggle between organisms to survive in a habitat with limited resources
the study of embryos and their development
molecular biology
The study of the molecular basis of genes and gene expression; molecular genetics.
