Answer:
1. Firstly, humans did not evolve from monkeys. Instead, monkeys and humans share a common ancestor from which both evolved around 25 million years ago. This evolutionary relationship is supported both by the fossil record and DNA analysis. A 2007 study showed that humans and rhesus monkeys share about 93% of their DNA.
2.This is because light must be bent more to reach the outer edges of the circular image. To correct for these aberrations and end up with the best image possible, the rectangular sensor crops out the outer edges of the circular image from the lens.
3. Let me answer from way out in left field. A Building is called a Building because it is to some extent always under construction, always changing a little from the original concept. Building continues. Architects often design buildings as if they were finished works of art. In reality, there are changes during construction to add such things as handrails at exterior steps, larger mechanical rooms expanded at the last minute, maybe a little more distance between ceiling and floor to allow for ducts or a last minute change in flooring, et cetera.
