It is present from the sea’s sunlit surface to its darkest depths. High in the atmosphere tiny creatures float about. Beneath our feet untold trillions of microorganisms are at work in the soil, making it fertile for the growing of green plants, which sustain other forms of life. 2.Nov 20, 2023 · Introduction. Despite how much we know about the state of the Earth 3–4 billion years ago and the complexity of the building blocks of life—DNA, RNA, amino acids, sugars—no entirely plausible scientific explanation for the spontaneous origin of life has been found. How life came from non-life, or abiogenesis, is still largely a scientific ... These features start to emerge in scattered patterns in ancient Africa. The oldest known H. sapiens skulls have similar faces to modern humans, but their skulls are long, not round. This suggests that our distinctive round skull and brain evolved within the H. sapiens species, not in those who came beforehand.
