"Shedding" Life to Other Planets...

Starchild: The Solar System (NASA)
"Asteroid impacts on the Earth may have scattered more life-bearing debris to Mars, Jupiter or beyond our Solar System than previously thought.

"Vast computer simulations of debris thrown up from Earth impacts show 100 times more particles end up on Mars than prior studies have shown.


"The highest-energy impacts drive debris all the way to Jupiter, which hosts two moons that may be amenable to life.

"Only the hardiest of Earth's organisms could have survived the trip, however.

"The study considers a reverse of the 'panspermia' idea that occupies much of meteoritic research - namely, that the precursors to life, or life itself, may have been delivered by an impact on the early Earth."

So...instead of random acts of deposit by asteroids on earth: we became "the donors."
