My Inner Fish

In the two videos we watched about how we were related to early animals like fishes and how they later evolved over millions of years into us. In the unit we are learning, we talked about different types of animals, and how they were similar to each other, making easy to order them into different areas. One such types were the ones that were focused on in the videos: the Fish and the Reptiles. In past units, we talked about evolution and why it occurs. This is especially shown as Fish went onto land and reptiles evolved into mammals. One such part in the video was the discovery of the Hadrocodium, whose name means big brain. This early mammal had a brain bigger than that of their body mass! This was used to allow for better performance in dangerous , and allowed them to survive in a world where dinosaurs lived. Another thing in the video that interests me is unexplored area in North America. When they talked about it, I was surprised by the fact that this place was not explored for years, even in times where the conditions there were low enough to do work in. Even with high-tech gear, people didn't want to travel in Canada because of the cold snow, and chance of getting lost in blizzards, and high chance of death.
