Earth, with its 4.5 billion-year-old history, holds many mysteries about the origin of life. Geologists previously believed that life emerged on Earth around a billion years after its formation due to the theory of the Late Heavy Bombardment, where intense space rock collisions were thought to have sterilized the planet. However, recent research challenges this notion.
According to Philip Donoghue from the University of Bristol, UK, the Late Heavy Bombardment may not have occurred as initially believed. Instead of a sudden bombardment event, evidence suggests that large impacts occurred sporadically over hundreds of millions of years. Additionally, a significant collision with a Mars-sized body early in Earth’s history could have vaporized any existing life forms.
Unraveling Earth’s Origins
The process of how life originated from inanimate matter remains a profound mystery. Despite extensive research, the timeline of this transformation is challenging to pinpoint due to the limitations of the fossil record.
