How Did Life First Originate on Early Earth?
How did life begin on Earth? The history of life on Earth traces the processes by which living and fossil organisms evolved from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago. Although there is some evidence of life as early as 4.1 to 4.8 Ga. It remains controversial due to the possible non-biological formation of the purported fossils.
How Did Life First Originate on Early Earth?
Life likely began on Earth’s early oceans through the combination of simple organic molecules. These molecules formed self-replicating molecules like RNA, leading to the emergence of single-celled organisms. Over time, some organisms developed photosynthesis, which released oxygen and transformed the atmosphere. Complex cells with a nucleus (eukaryotes) evolved, followed by multicellular life. Through mutation, natural selection, and genetic drift, life diversified into various species, including plants, animals, and humans
