The skull is of Sahelanthropus tchadensis, an extinct hominid species dating back about 7 million years. Whether it is really part of the hominina tree is unclear; there are conflicting views that it is either part of the human tree or the chimp tree. It very well could be the earliest human ancestor. The next time somebody tells you that humans did not evolve from apes, tell them they are absolutely right and that they should read up on early hominid species on wikipedia because it is really interesting. Derp derp, we didn't evolve from no monkeys! Of course we didn't, but we did have a common ancestor though that we diverged from. That's my opinion anyways.
The bottom one is a fossil Canis lupus, or a wolf, which is where puppies came from. :]
I made that during a break from studying for my endocrine/neuro exam. See you all soon, we have big news brewing.
