Fossil - remains of once living things from the past, Radio active decay - Absolute dating on a fossil that uses the 1/2 life of radioactive elements, Precambrian - the division of time that CYANOBACTERIA lived in and created oxygen, Cyanobacteria - a blue green algae that was the first to create oxygen for the earth, Paleozoic - division in time that the living species lived in the oceans, Mesozoic - division in time that there were dinosaurs living on the earth. The asteroid impact ended this Era, Cenozoic - division in time that there were mammals on the Earth, we live in this Era, Punctuated - An abrupt change in the evolution because of a environmental change. (toothpick lab after the chemical spill and the green fish all died and the green allele was dominate and was taken out), Spontaneous Generation - The belief that living things come from non-living, Endosymbiosis - When the protocels "eat" a mitochondria and a chloroplast and creates a Eukaryotic cells, Evolution - Change in species over a long period of time, Charles Darwin - Wrote the book the Origin of the Species, was the Naturalist on the HMS beagle and studied the Galapagos islands (Finche and Turtles), Natural Selection - Having an adaptation that makes you fitted for the environment so you can survive long enough that you pass on your trait to the next generation, Gradualism - The gradual change over time in a population (the toothpick lab in the first 3 generations), Mimicry - when one species look like another to aid in their survival (visceroy and Monarch butterfly), Camoflage - When an organism blends in to the environment for survival, Homologous structure - Evolution evidence that shows how closely related organisms are to each other by how they have the same bone structure. (Bats, birds, cats, whales, humans), Analogous structures  - Evolution evidence that shows that organisms are not closely related. they have similar structures (wings, fins) but only because they live in the same environments., Vestigal structure - Structures that are not used anymore by an organism because they are not needed (the hip bone of a whale), Embryology - Evidence of evolution, the early stages of development in an organism where they all look similar (gill slits and a tail),
