1. discipline that searches for life
beyond earth; heavily dominated by physical scientists. Astrobiologists do not limit themselves solely to the search for life
, but also look for such things as prebiotic molecules
in interstellar space, solar systems
in the process
of forming, and mature
planets orbiting other stars.
2. specific anthropic
subtheory associated with Rhawn Joseph, who
proposed that genetic
seeds encased in stellar debris have bootstrapped life
in many locations throughout the universe. The Joseph subtheory is specifically anti-Darwinian.
