It then evolved into the Ambulocetus which has a slightly shorter tail. This is because the long slender tail is not very useful in the watery environment the Ambulocetus lived in. Today, the toothed whale has a shorter tail that is fatter and has a fluke to help get around the sea.]]> 2017-05-15 19:32:17 UTC https://padlet.com/64383/x159vupyslbn/wish/171936805 64383 https://padlet.com/64383/x159vupyslbn/wish/171937502 Ambulocetus Natans Thewissen]]> 2017-05-15 19:36:12 UTC https://padlet.com/64383/x159vupyslbn/wish/171937502 64383 https://padlet.com/64383/x159vupyslbn/wish/171940077 2017-05-15 19:50:25 UTC https://padlet.com/64383/x159vupyslbn/wish/171940077 64383 https://padlet.com/64383/x159vupyslbn/wish/171972279 2017-05-16 00:05:13 UTC https://padlet.com/64383/x159vupyslbn/wish/171972279 64383 https://padlet.com/64383/x159vupyslbn/wish/171979910 2017-05-16 01:19:22 UTC https://padlet.com/64383/x159vupyslbn/wish/171979910 64383 https://padlet.com/64383/x159vupyslbn/wish/171980485 Based on the Manx gene, the Ambulocetus share only a little DNA with humans. Humans develop tail bones, but do not have real tails. The Ambulocetus has a fully developed tail feature. In humans the tailbone is a vestigial structures as humans evolved from organisms with tails, but these functions are no longer used. The human tailbone is leftover from evolution. The ambulocetus has a tail bone as well, but also features a tail itself. It is used to swim, make quick maneuvers, and defend itself against other organisms. ]]> 2017-05-16 01:25:28 UTC https://padlet.com/64383/x159vupyslbn/wish/171980485 64383 https://padlet.com/64383/x159vupyslbn/wish/171980740 2017-05-16 01:29:05 UTC https://padlet.com/64383/x159vupyslbn/wish/171980740 64383 https://padlet.com/64383/x159vupyslbn/wish/171980773 2017-05-16 01:29:32 UTC https://padlet.com/64383/x159vupyslbn/wish/171980773 64383 https://padlet.com/64383/x159vupyslbn/wish/172428663 The Ambulocetus is related to organisms today because of the evolutionary tree, DNA comparison, and the fossils.

1. The ambulocetus and the hippo are closely related because they both nurse underwater. They have the closest relation on the tree because they are the only organisms that carry this trait. The ambulocetus and the insect are far less related on the evolutionary tree. The closest trait they both have is the bilateral symmetry, but that trait is second from the bottom of the tree meaning the relationship is not closely related.
2. Out of the 260 DNA pairs, toothed whales had 96% matched percentage with the Ambulocetus. This shows that toothed whales and the Ambulocetus had a lot in common on the DNA level with organism 3.
3. At the start, the Pakicetus had a long slender tail. It then evolved into the Ambulocetus which has a slightly shorter tail. This is because the long slender tail is not very useful in the watery environment the Ambulocetus lived in. Today, the toothed whale has a shorter tail that is fatter and has a fluke to help get around the sea. The pakicetus skeletons are found farther down than the ambulocetus and toothed whales, with toothed whales closer to the surface.

The Ambulocetus shared a lot of traits with hippo’s today including nursing underwater. The DNA of the Ambulocetus and the DNA of toothed whales are very similar. They have 96% matched DNA pairs. The skeleton of the ambulocetus and toothed whales are also very similar. They both of a somewhat long skull, they both have tails, and they have similar forearm structure.
