Charles Darwin had a theory of evolution, his selection theory starte when he discovered island finches who had different shapes and sizes of beaks, which matched what they ate. Thick large beaks for tough nuts, slim, curved beaks for nectar and bugs. ]]> 2017-06-09 15:41:25 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/175896436 hannah_ritter https://padlet.com/hannah_ritter/l0w4z8827rma/wish/175896791 There is variation of traits, like black and red ants in an area. Since the environment can't support unlimited, so an anteater comes and eats the black ants. The surviving red ants build their colony to have even more red ants, eventually, the colony only consists of red ants. ]]> 2017-06-09 15:45:33 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/175896791 hannah_ritter https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176116988 Variation = Mutation 
Inheritance = DNA & Sexual selection
Selection = Generic Drift 
Time = Migration/Gene flow ]]> 2017-06-12 15:21:16 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176116988 hannah_ritter https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176117989 Mutations are small errors in DNA coding during cellular reproduction. These mutations can either benefit or harm. An example for harmful mutation can be an albino rabbit. It's predators can easily spot it in the tall grass. So the rabbit has to stay in a low area, and depend on another rabbit to feed it. ]]> 2017-06-12 15:28:05 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176117989 hannah_ritter https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176120068 The passing on of genetic info, it's mostly influenced by male competition over a female. Depends how impressive the competition is! An example of this is when the male cuttlefish compete by their flashing colors to attract female cuttlefish, they often fight over the female. ]]> 2017-06-12 15:41:39 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176120068 hannah_ritter https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176122599 Gene flow is the exchange of genes between two separate populations. This is most often accomplished when animals or spores from plants migrate to a new area. An example would be a bee carrying the pollen of a different flower to another species of flower, passing genes to the species. ]]> 2017-06-12 15:58:30 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176122599 hannah_ritter https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176268892 Definition: Two or more related species becoming less similar over time. The finches below had the same common ancestor, but over time, food became scarce and they had to scatter out, evolving their size and shape of beaks to survive better in their environment. Charles Darwin has studied these finches. ]]> 2017-06-13 15:23:12 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176268892 hannah_ritter https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176270375 Definition: Two different species evolve similarly because of their lifestyle. The picture below is a good example of fish that look the same, but they aren't. It's their lifestyle and their adaptation to the environment that surrounds them. ]]> 2017-06-13 15:32:56 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176270375 hannah_ritter https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176274668 Definition: Organisms w/ different ancestors but similar structure. ]]> 2017-06-13 15:56:57 UTC https://padlet.com/hannah_ritter/l0w4z8827rma/wish/176274668
