Vocabulary Definitions: Artificial Selection-intentional breeding for certain traits to benefit humans Competition-Struggle for existence organisms compete for resources (i.e. food, water, territory, mates, etc.) Fitness-the ability of an individual to survive and reproduce in a specific environment Adaptation -any inherited characteristic that increases an organism's chance of survival Natural Selection-certain traits are favorable allowing for individuals to survive and reproduce resulting in changes in the inherited characteristics of a population over time Descent with Modification-each living species has descended, with changes, from other species over time. It implies common ancestry and natural selection. Common Ancestor t he theory that all living organisms on Earth are descended from and share lineage from a single ancient organism. Fossil Record Compare fossils from rock layers to document that life on Earth changed over time. Geographic Distribution is evidence that depicts common ancestry and descent with modification Homologous Body Structures- Structures that have different mature forms but develop from the same embryonic tissues Vestigial Organs organs reduced in size so that they are just traces (vestiges) of homologous organs Similarities in Embryos-The early stages of many animals with backbones are very similar. Overproduction-more offspring born than will survive Variation of Offspring-offspring are not alike and have different traits that may promote their survival
Relative Dating-Age is determined by comparing its placement with that of fossils in other layers of rock. Radioactive Dating-the absolute age of a fossil is calculated based on the amount of remaining radioactive isotopes it contains. Half-life-the time it takes for half of the radioactive isotope to decay. Mass Extinction- mass death resulting in ecological opportunities for organisms that survived and evolution that produces many new species Adaptive Radiation process by which a single species or a small group of species evolves into several different forms that live in different ways Convergent Evolution the process by which unrelated organisms come to resemble one another. Analogous structures Structures that look and function similarly but are made up of parts that do not share a common evolutionary history Coevolution The process by which two species evolve in response to changes in each other over time Punctuated Equilibrium periods are interrupted by brief periods of more rapid change. Gradualism slow and steady change over time Relative Frequency-number of times the allele occurs in a gene pool Directional Selection trait at one extreme is favored Stabilizing Selection intermediate trait is favored Disruptive Selection traits at both extremes are favored Speciation is the formation of new species Reproductive Isolation members of two populations cannot interbreed and produce fertile offspring
Behavioral Isolation populations capable of interbreeding but have different courtship rituals or other reproductive strategies that involve behavior Geographic Isolation two populations are separated by geographic barriers rivers, mountains, oceans. Temporal Isolation occurs when two or more species reproduce at different times.
