The species that you and all other living human beings on this planet belong to isHomo sapiens. During a time of dramatic climate change 200,000 years ago, Homo sapiens evolved in Africa. Like other early humans that were living at this time, they gathered and hunted food, and evolved behaviors that helped them respond to the challenges of survival in unstable environments.
Sedimentary rocks are made from eroding other rocks and they are deposited on other rocks, they are younger than the underlaying rocks hence could only be formed on older underlaying rocks. If u have any more questions feel free to ask!
