This shows a drought occurred and the rainfall decreased by 110mm making animals die. ]]> 2020-02-07 15:54:59 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442219050 Evidence number two claytonmurray24 https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442220998 In 1976 the average seed abundance for the portulaca seed was 11.3 in 1978 was 0.45 because of the drought in 1977, the average seed abundance for the tribulus seed in 1976 was 10.5 and in 1978 the average decreased to 5.083. ]]> 2020-02-07 15:58:07 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442220998 Claim: which mechanism of the microevolution caused the beak of the medium ground finch population on daphne major increase in size from 1976 to 1978.

The beak length also increased from 10.70952064 to 11.60677419. they did all of this because of natural selection and needing to survive. ]]> 2020-02-07 16:10:14 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442230595 Reasoning claytonmurray24 https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442235996 natural selection caused the change in the finches beak because of the little rain we saw in 77 it caused the food abundance to decrease. The portulaca or the easier soft seed decreased to zero so the finches were only left with the tribulus seed or the hard and difficult to eat seed. the finches beaks were not meant for this seed so they all died off.this is why we saw a decrease in population. The finches beaks were not meant for the seed so the bird's beaks changed to adapt to the oly food left. the beck then increased in size and depth because of the natural selection.Natural selection is when a trait variation affects the survival or reproduction of an animal.]]> 2020-02-07 16:17:49 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442235996 Tribulus seed claytonmurray24 https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442242368 2020-02-07 16:27:45 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442242368 Portulaca seed claytonmurray24 https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442243023 2020-02-07 16:28:39 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442243023 Graph of rainfall claytonmurray24 https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442243898 2020-02-07 16:29:53 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442243898 Graph of population claytonmurray24 https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442245704 2020-02-07 16:32:19 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442245704 claytonmurray24 https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442251373 2020-02-07 16:40:33 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442251373 claytonmurray24 https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442251874 2020-02-07 16:41:20 UTC https://padlet.com/claytonmurray24/vjbetscakzh1/wish/442251874
