Stickleback Fish

The first topic I chose is v. Essential Knowledge 1.B.1: Organisms share many conserved core processes and features that are evolved and are widely distributed among organisms today. Something that I learned about this topic is that a fish called a stickleback found in the ocean, ended up also being found in a lake. The stickleback fish found in the ocean has fins on its belly which look like spikes and the stickleback fish found in the lake didn’t have any signs of spikes. However, there is a sign of traces of bone from where the spikes where located. They noticed that the left side was bigger than the right side. I was shocked when they showed a picture of the stickleback fish from the lake with the traces of bones from the stickleback fish
