When the drought came, only the birds with large beaks survived and reproduced. All the birds with the large beaks would have passed down the mutation to their offspring and the cycle would continue.]]> 2021-02-03 15:06:46 UTC https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159135731 ethanwhite25 https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159237473 Ground Finch]]> 2021-02-03 15:23:14 UTC https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159237473 ethanwhite25 https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159240681 Drought]]> 2021-02-03 15:23:45 UTC https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159240681 ethanwhite25 https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159260749 Tribulus]]> 2021-02-03 15:27:06 UTC https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159260749 ethanwhite25 https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159265207 Portulaca]]> 2021-02-03 15:27:54 UTC https://padlet.com/ethanwhite25/d1avvfjjsc0txw7u/wish/1159265207
