The tribulus plants survived because they didn't need as much water as the portulaca plants. This caused the birds with smaller beaks to die due to the fact that they can't eat the hard tribulus seeds. The birds with longer beaks survived since they can eat the tribulus seeds.]]> 2019-02-06 18:13:35 UTC https://padlet.com/emmagilkison23/9otknarumzrw/wish/328408399 emmagilkison23 https://padlet.com/emmagilkison23/9otknarumzrw/wish/328412601 In 1978 the medium ground finches had an offspring causing them to increase in size]]> 2019-02-06 18:20:41 UTC https://padlet.com/emmagilkison23/9otknarumzrw/wish/328412601 emmagilkison23 https://padlet.com/emmagilkison23/9otknarumzrw/wish/328414275 For 551 days the islands received no rain. Grants returned to Daphne Major to document the effect of the drought on the next generation of medium ground finches. They measured the offspring and compared their beak size to that of the previous generations. They found the offsprings' beaks to be 3 to 4% larger than the previous generation.]]> 2019-02-06 18:23:13 UTC https://padlet.com/emmagilkison23/9otknarumzrw/wish/328414275 emmagilkison23 https://padlet.com/emmagilkison23/9otknarumzrw/wish/328416546 The tagged finches' population dropped down to only 90 left, where the small beaked finches died off.]]> 2019-02-06 18:26:24 UTC https://padlet.com/emmagilkison23/9otknarumzrw/wish/328416546 emmagilkison23 https://padlet.com/emmagilkison23/9otknarumzrw/wish/328439074 243 large beak Medium Ground Finches were alive and sense the birds reproduced their would be more and more generations with the large beak trait. Although only 90 small/thin beak Medium Ground Finches lived would not have that specific trait carried on to next generations. Now that the future generation have the large beak trait to these Medium Ground Finches, which in other words is, Natural Selection. ]]> 2019-02-06 19:00:42 UTC https://padlet.com/emmagilkison23/9otknarumzrw/wish/328439074 emmagilkison23 https://padlet.com/emmagilkison23/9otknarumzrw/wish/338049653 2019-03-05 18:10:11 UTC https://padlet.com/emmagilkison23/9otknarumzrw/wish/338049653
