Some of these insects began growing wings Hemimetabolous were there is no pupa stage. The loss of oxygen in the atmosphere caused the dragonfly species to shrink in size to hte dragonflies we see today.]]> 2017-06-08 20:26:21 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/175794040 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/175920916 2017-06-09 20:51:57 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/175920916 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/175921528 V- variation

Simply put VIST are the four things that cause evolution.]]> 2017-06-09 21:06:47 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/175921528 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/175921720 natural selection is when animals have to fight to stay alive.

A mutation is when the DNA is accidentally replaced causing something to be different then the original plan. ]]> 2017-06-12 20:50:58 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176159855 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160046 This is when genes are passed fro one generation to the next. which leads to mixing up of genes]]> 2017-06-12 20:52:37 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160046 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160101 Divergent evolution is when the same species grow apart in the evolution process.
Parallel evolution is when two different species follow the same path of evolution. so if one animal changes in one way another animal changes in the exact same way.
Convergent evolution is when two different species eventually come together.]]> 2017-06-12 20:53:27 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160101 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160354 In most animal kingdoms males fight for females attention, and usually the best male wins. This is an example of sexual selection. ]]> 2017-06-12 20:57:07 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160354 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160539 When one animals genetics allow it to live longer then another of the same species with different genes]]> 2017-06-12 21:00:15 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160539 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160711 Homologous Structures is when an organ or bone leading to beliefs of common descents. For example humans have tail bones.
Vestigial organs are organs that are there but have no use in that species.
ORP is when a species grows the same way as another.]]> 2017-06-12 21:03:02 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176160711 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176161314 Molecular evolution allows use to date matter by seeing how much the molecules have changed over time.]]> 2017-06-12 21:12:10 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176161314 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176313960 2017-06-13 20:38:10 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176313960 elizabeth_mathlin https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176314632 6th period]]> 2017-06-13 20:45:02 UTC https://padlet.com/elizabeth_mathlin/qd9qaai0zk7c/wish/176314632
