" With modern technological know-how, there are many other sorts of proof for evolution. This features similarities within the embryos of different species, the same DNA sequences uncovered throughout all species, and an idea of how DNA mutations get the job done in microevolution. A lot more fossil evidence has also been found considering the fact that Darwin's time, Whilst there are still numerous gaps inside the fossil record.
yeah, and We've additional function on account of arms and like thinking we arent the strongest creature undoubtedly but we innovate,
