5. Evolution of living thingsSpecies – a group of organisms that can mate and produce fertile offspringEvolution does NOT occur to individuals (you) it occurs to the whole species (human beings)Speciation Event – When one species evolves into two new species
6. Evolution of living thignsPlants and AnimalsAll organisms go through evolution including plants, animals and even bacteria!
7. Evolution of living thingsAdaptation – a trait that is advantageous (good) in the species current environment that is evolved through the process of natural selectionBecomes more common because they survive betterNatural Selection – changing the physical appearance of a species based on survival rate

9. Evolution of living thingsIn order to Survive Organisms do not adapt and evolve because they feel like it, they evolve because something in their environment is pushing them toward that traitAnimals who don’t have the trait pass awayWhat Types of ThingsPredatorCompetitionFood SourceClimate Change (good or bad)Sexual Selection
10. Evolution of living thingsLong Periods of TimeAlways remember we are dealing with huge lengths of time with Earth Science and Evolution“Fast” could still mean thousands of years“Slow” could mean millions!
11. Evolution of living thingsEvolutionary TreesAn evolutionary tree shows the history of a species through long periods of timeSimilar to a family treeShows which species have gone extinct along the way

Evolution of living thingsEvolutionary TreesAn evolutionary tree shows the history of a species through long periods of timeSimilar to a family treeShows which species have gone extinct along the wayEvolutionary LineThe direct line on the tree that leads to a specific speciesThese trees have different branches, each branch is related but NOT directlyKind of like your Uncle and you

17. Evolution of living thingsExtinctionThe process of reducing a species population to 0Along the way (as it decreases) they are called EndangeredFossil Record ConnectionThe fossil record allows us to do two VERY important thingsIt allows us to trace and follow the evolution of a species through time in order to build and understand Evolutionary TreesIt also allows us to determine when a species goes extinct
