The drought killed off the soft-shelled portulaca seed and left only the hard-shelled one.  The hard-shelled seed is difficult to eat, but birds with longer deeper beaks could eat the hard-shelled seed easier than the finch birds with short beaks.  ]]> 2020-02-07 16:27:52 UTC https://padlet.com/annacollins24/ocd2i8v089vp/wish/442242445 Rainfall annacollins24 https://padlet.com/annacollins24/ocd2i8v089vp/wish/442243123 Due to the amount of rainfall in 1977 natural selection came it to play when the portulaca seed died out it left the Tribulus seed left so the birds have to adapt to their environment to get food from the the Tibulus because the rainfall killed all the portulaca seeds ]]> 2020-02-07 16:28:49 UTC https://padlet.com/annacollins24/ocd2i8v089vp/wish/442243123 Medium Ground Finch Population annacollins24 https://padlet.com/annacollins24/ocd2i8v089vp/wish/442246118 All the birds with short beaks died off due to natural selection for their main food source, the portulaca seed, went extinct and they didn’t have the same adaptations as the birds with long beaks.  And then with only the long-beaked birds left they were the only birds to reproduce, long beak plus long beak equals longer beak.  Explaining the increase in beak length.
