Inheritance- Characteristics transmitted to an offspring.
Selection- The best organisms adapt to their environment and tend  to survive and transmit their genetic characters.
Time-The change of state brought about the passage of time.]]> 2017-06-09 19:21:06 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/175916140 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/175916483 2017-06-09 19:25:29 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/175916483 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/175917139 2017-06-09 19:35:44 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/175917139 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176153197 A major extinction, occurred at the boundary that marks the beginning of the last phase of the Devonian period, about 360-375 million years ago. 19% of all families and 50% of all genera became extinct.]]> 2017-06-12 19:32:07 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176153197 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176153846  The Permian extinction, known as the Great Dying, I occurred about 252 million years ago, forming the boundary between the Permian and Triassic geologic periods, as well as the Paleozoic and Mesozoic eras.]]> 2017-06-12 19:37:44 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176153846 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176154347 Ordovician-Silurian mass extinction had two peak dying times separated by hundreds of thousands of years. Most life was in the sea, so it was sea creatures such as trilobites, brachiopods and graptolites that were reduced in number.]]> 2017-06-12 19:43:33 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176154347 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176154618 The Triassic–Jurassic extinction event marks the boundary between the Triassic and Jurassic periods, 201.3 million years ago, and is one of the major extinction  events of the Phanerozoic eon, profoundly affecting life on land and in the oceans.]]> 2017-06-12 19:46:33 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176154618 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176154997 A mass extinction of some of three- Quarters of the plant and animal species on earth approximately 66 million years ago.]]> 2017-06-12 19:50:02 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176154997 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176498352 National selection- organisms adapt to their environment so they can survive and produce more off spring.
Mutation- changing a structure of a gene.
Migration- when a animal moves from one region to another in seasons.
Divergent evolution- tracing back two or more species to their common ancestor.
Parallel- finding similar traits, starting at a common ancestor.
Genetic Drift- disappearance of particular genes as individuals die or do not reproduce.
Homologous structures- when very different animals have bones that look the same and that seem to look related. ]]> 2017-06-15 05:03:28 UTC https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176498352 joanna_henry1 https://padlet.com/joanna_henry1/gct76ognwnfk/wish/176498906 Vestigial or- a rudimentary structure in humans, a functional structure.
Convergent evolution- organisms not closely related but share a common ancestor.
Sexual selection- getting characteristics for both parents.
Ontogeny recapitulates phylogeny- it's a catchy phrase, means development of an organism meaning ancestors throughout evolution.
