Didn’t we all think that? ;)
- dboreham 9y agoI've long wondered about this : if it can be shown that there isn't enough delta(t) in earth history for all of evolution to have happened, then some of evolution must have occurred somewhere else. Life, in at least some form, moving from other star systems seems at least not completely impossible.
- SlowRobotAhead 9y agoSure, but the issue is humans would be such an accident that you’d have to think we’d almost be considered an undesirable element or virus to whatever intentions a pollination device would have had. Hope they never come back to check on us, one look at Instagram and we’re gone.

- searine 9y agoEvolution functions on a model of "punctuated equilibrium". Lots of time doing nothing, with sporadic bursts of change. So there is more than enough time for evolution to occur, even on a drastically shortened earth timeline. Most of the time, life is just maintaining the status-quo, until outside factors tilt fitness in one direction and the system readjusts.
- dboreham 9y ago>So there is more than enough time for evolution to occur, even on a drastically shortened earth timeline. Curious to know how this is known as a fact? Also, I realize that in the fossil record we see "jumps" from one species to another in a relatively short time but is that how the underlying changes in DNA actually occurs? If so, how? Everything I've learned suggests that DNA modifications are made under some stochastic process.
