Ever think where did we come from? Well, one answer to that could be evolution. While it is not yet a proven fact, it is a theory that shows promise to be true.
Experts on the matter of evolution “recorded 4,500 physical traits for 86 mammalian species, including 40 that are now extinct.” Using this information in tandem with DNA samples, the experts were able to figure out the probable start of placental mammals. One of the findings was that the rise of placental mammals came after the dinosaurs had become extinct. This was an earlier hypothesis that was now confirmed. The death of the Dinosaurs would allow for mammals to fill the top of the food chain where the dinosaurs once stood. Less competition makes it easier to rise to the top. Dr. Jonathan Bloch, who works at the Florida museum of Natural history, said “This gives us a new perspective of how major change can influence the history of life, like the extinction of the dinosaurs. This was a major event in Earth’s history that potentially then results in setting the framework for the entire ordinal diversification of mammals, including our own very distant ancestors.”
I think this is incredibly cool how all species could be related to one primal and ancient ancestor. It shows how we are all linked in some way.
What do you guys think on the matter?
