You can also see that the Archaeopteryx and the Waldrapp Ibis are both very closely related because they each have five traits in common on the evolutionary tree. The more traits organisms have in common the more closely related they are due to evolution. The more traits they have in common the closer they are because it makes them more similar. ]]> 2017-05-17 15:23:27 UTC https://padlet.com/559521/5ekh1fjm0j3s/wish/172360918 559521 https://padlet.com/559521/5ekh1fjm0j3s/wish/172424373 Evolution is shown in the fossils of these organisms in their wings. In the Archeopteryx you can see that it has the radius and humerus but at the end only has two claws. Then you look at the structure of the present day bird which is the White-tailed Tropicbird it also has the humerus and the radius but instead of just the two claws it has three. This could have happened to assist the bird in its environment. This shows that over time the organism changed, but do to its structural similarity they both came from similar ancestors.

While looking at the other organisms, you can see that they look very similar. In the second stage of embryology, the chick’s tail is receding slightly but not by much. In the third stage of embryology, the chick tail has receded massively but is still visible on the fetus. This means that the DNA sequence of the MANX gene remained relevant and continued until the end of the sequence resulting in a tail in the fetus. Since the chick ended up with a tail, it means that the MANX gene stayed prevalent throughout the sequence.]]> 2017-05-17 23:17:14 UTC https://padlet.com/559521/5ekh1fjm0j3s/wish/172455115 559521 https://padlet.com/559521/5ekh1fjm0j3s/wish/172455909 https://docs.google.com/a/sunprairieschools.org/spreadsheets/d/158Gs7dgnTkrnqndkVZPkEWLEQkSbrp6RXRDEE-TirBM/edit?usp=sharing]]> 2017-05-17 23:22:29 UTC https://padlet.com/559521/5ekh1fjm0j3s/wish/172455909 55930 https://padlet.com/559521/5ekh1fjm0j3s/wish/172461901 2017-05-18 00:28:00 UTC https://padlet.com/559521/5ekh1fjm0j3s/wish/172461901 559521 https://padlet.com/559521/5ekh1fjm0j3s/wish/172597393 2017-05-18 14:36:53 UTC https://padlet.com/559521/5ekh1fjm0j3s/wish/172597393 559521 https://padlet.com/559521/5ekh1fjm0j3s/wish/172597719 2017-05-18 14:38:00 UTC https://padlet.com/559521/5ekh1fjm0j3s/wish/172597719 559521 https://padlet.com/559521/5ekh1fjm0j3s/wish/172604956 https://docs.google.com/a/sunprairieschools.org/document/d/1_K8nVeJPSeY_NUSK9gHrbRW3twt8vphda26j_7JPB7Q/edit?usp=sharing]]> 2017-05-18 15:02:54 UTC https://padlet.com/559521/5ekh1fjm0j3s/wish/172604956
