Document Summary
Wrote on the origin of species by means of natural selection . At the time, many people believed that species did not change over time. Went on voyage in hms beagle to s american coast. Observations showed studying species living close to one another was more efficient than studying similar environments to see organism relationships. To help them survive adaptations and has evidence. Natural selection - certain traits increase survival and reproductivity rates. As species accumulated in different habitats, they acquired different. Imprints, footprints, body parts rich in minerals (shells, teeth, bones) Many found in fine-grained sedimentary rocks formed from sand and mud at bottom of bodies of waterlayers of sediment continue to build to form layers called . Idea that species today come from ancestral species. 13. 3 transitional forms of fossils land to water mammal. Since, evolution causes species to change over time due to environmental factors, related species may have similar parts that have different functions functions.
