Elephant FISH and Sharks. There's a similarity? 0_0

The thought of an elephant fish shocked me. To my surprise, I had not even known that "we humans" are related to fish!!! It turns out that that same gene in those fish control the devolepment of our body parts controls the growth of some of the appendages for that fish! Calling it the "sonic hedgehog gene" is responsible for deciding whether to turn the embryo into a elephant fish or a shark. Basically, they're close-distant relatives. To find this out, scientists went diving for these eggs and taking them to the lab. As they took control of the genes for the shark embryo, they were able to see that elephant fish came to have one brachial ray while sharks have five. This could have been a sign of evolution. While they tried the gene on the dogfish sharks, it had ended up with a growth of fins just like the other sharks. Maybe the "Sonic Hedgehog" gene could allow evolution into the different animals in the sea. Neil Shubin, a professor at Chicago University says "Not only are we seeing the history of how organs are built, but we're seeing the history of the tool kit." The next step? Based on the article on Livescience.com, they will try to use the "Sonic Hedgehog" to prove the comparison between cl gene activity and brachial ray growth.
