| Jan 14 at 13:51 | comment | converted from answer | Matt Wasz | Life on Earth likely didn’t start from scratch though. It’s also not 100% clear how far along Earth’s starter-package was but I’ve read estimates that we got a 0.5-4.0 billion year head start. So evolution of complex life is likely not dependent too much on the life of the star rather how far along the starter-package is. | |

If fixed some grammatical errors and made a sentence make more sense.

| Dec 4, 2022 at 7:34 | comment | added | ZuOverture | Planets seem to form much faster than in 2 billion years. Earth isn't even 100 million years younger than Sun, and had oceans within 100 million years from its birth. F-type star shouldn't differ too much from G-type Sun in terms of time required for planet formation. | |

| Dec 3, 2022 at 19:23 | comment | added | M. A. Golding | @AlexP Humans evolved from single-celled lifeforms in about 600 million years, but those single celled lifeforms 600 million years ago were the product of billions of years of evolution after the first life forms on Earth. The question was about total time between planetary formation and intelligent life. | |

| Dec 3, 2022 at 18:32 | comment | added | BillOnne | Why should hermaphrodites evolve faster? The species that exist that are herms are not noticeably better adapted, so far as I can tell. Also, what form of herm is this? Can they self-fertilize? Are they always "both" or do they alternate male for a time then female for a time? | |
