As shown in the decrease in the population when it went from 751 birds in 1976 to the year of drought where the population dropped to 186 birds at the end of 1977.]]> 2021-02-03 15:53:19 UTC https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159419473 riannemccaleb25 https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159420865 The birds with the longer beaks could better reach the limited amount of seeds while the shorter beaked birds would starve and end up dying. Before the drought the seeds were 9 and 10 square meters and after the drought they were only 8 and 3 square meters.]]> 2021-02-03 15:53:33 UTC https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159420865 riannemccaleb25 https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159422161 The birds with the longer and larger beaks could survive with the changes to seed type while the birds with smaller beaks died off. ⅓ of the population decreased due to starvation]]> 2021-02-03 15:53:46 UTC https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159422161 riannemccaleb25 https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159426092 This proves that it was natural selection because the birds with longer beaks could more easily reach the small amounts of water, and those who didn’t ended up dying off because they were unable to get to the water to survive.]]> 2021-02-03 15:54:28 UTC https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159426092 riannemccaleb25 https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159427518  This proves that is natural selection because of the drought there was limited seeds so the birds with smaller beaks couldn't reach the seeds in the plants and the birds with longer beaks could reach the seeds into the plants/flowers. So now that the seeds are larger and there are less seeds they need longer beaks in order to get the seeds easier.]]> 2021-02-03 15:54:43 UTC https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159427518 riannemccaleb25 https://padlet.com/riannemccaleb25/9ba1hn95tbbgudl5/wish/1159428798 This is because due to the drought the larger seeds were more abundant while there was few small seeds so the birds with larger beaks could easily crack the larger seeds while the short beaked birds could not.
