My Zen Arcade

Discovery.com
has an article on how evolution seems to have occurred in bursts (at
least in some instances). But what I wanted to point out was this:

During about two hundred million years, organisms grew
from cells invisible to the naked eye to organisms about the size of a
thumbnail

I think there’s this misconception about how long we mean when we say
“evolution takes place over a long time”. Some people think thousands
of years. But that’s nothing. Read that quote again.
200 million years.
That’s the kind of timeframe we often talk about.
Unfortunately, that’s why the idea of a ‘missing link’ is a straw man
created by creationists. There is no ‘one step’, where we go from one
species to another. It is over massive amounts of time (even
accepting the burst ideas), very VERY gradual. That lets creationists
demand that scientists get more and more specific in this whole
missing link thing, “that one isn’t as upright” or “that one has a
funny nose still”.
And there’s no real way to ever get there.
