And the "missing link" chain is now, what, about a mile long? But, there is room for more.
Of course you won't remember everything and there will be gaps - ie. "missing links" between some of your activities.
Does this mean that you really didn't do ANY of those activities yesterday? I think you would say "no - of course I did them - I just can't remember what I did in between"
And this is with things you did in the past 24 hours!!!
Does this make all of the things you DID remember and put on the list "wrong"?? Did yesterday not exist for you because of "gaps in the record"??
Now, try the same activity for a week ago - a year ago.
Massive amounts of gaps, -eh?? But, the things you DO remember actually did happen.
Now, imagine applying the same logic to bones that only RARELY fossilize and are even more rarely found.
Of COURSE there are going to be gaps. And, little by little, finds are made that start to creat a better picture. Like your memory of one year ago, some gaps will never be filled - others will be filled in great detail showing minute chanages over time..
"Gaps" don't invalidate what happened in the past.
What's this going to be called now? Piltdown Woman?
Yeah. Every time they fill a gap, it creates two new gaps on either side.
Do the math.
