Evolution 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.

>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.
