The portulaca seed went from 18 per square meter in May of 1976 before the drought to 0 per square meter in November of 1977 after the drought (evidence is from Lab 18 data sheet)

Overtime due to natural selection the beaks grew/got bigger so then finch could eat the tribulus seeds. ]]> 2020-02-07 14:25:39 UTC https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442153777 reesediesel24 https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442159460 Evidence 2 supports the claim that natural selection happened because after the drought the medium ground finch population beak size grew dramatically, meaning that the medium ground finch population had evolved during and after the drought to survive. The reason they had evolved so quickly is because all the portulaca seeds had withered away causing the medium ground finch population to go through natural selection to survive in their new environment. ]]> 2020-02-07 14:33:51 UTC https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442159460 reesediesel24 https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442160417 Evidence 1 supports the claim that natural selection happened because since there was a lack of food causing the medium ground finch population to decrease the medium ground finch then needed to go through evolution and get larger and thicker beaks to survive and to eat the tribulus seed.]]> 2020-02-07 14:35:22 UTC https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442160417 reesediesel24 https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442446442 2020-02-07 23:05:56 UTC https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442446442 reesediesel24 https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442544561 2020-02-08 15:40:27 UTC https://padlet.com/reesediesel24/oku0yt15v5n9/wish/442544561
