Question 1:

This has been on my mind for a while now.
When they dug up the bones of the Homo Habilis and Homo Erectus (hahahah!) and the Australopithecus ect. and I was wondering:

did they find any bones during the transaction between one level to the next? According to scientists evolving takes dozens of generations for there to be even the tiniest changes. So we shoulda found bones of them gradually changing right?

So have we ever found bones that show these changes?

Question 2: How do we know how long bones have been buried? I heard it had to do with radiation.

EDIT: Thanks in advance. =D

I got another question. How do they know how long the Earth existed?

Answer 2: Radiocarbon dating. Basically we look at the carbon ( a specific brand of carbon called carbon 14) in the fossils and judge how old they are based on how decayed (radioactive decay) the carbon is. That's a very dummed down version because it's late and I can't think of the specifics off the top of my head.

Also, this may just be the first ever thread with the words "questions" and "evolution" in it that doesn't involve the word "monkey" in the OP. At least it's the first I've seen. Congratulations

(1) We have plenty of transitional fossils of our genus and related genus.

(2) We do not use carbon dating, since it is only valid up to around 50 000 years. We use other dating techniques that are much more reliable, using a minimum of a half a dozen isotopes.

(3) We use dating methods such as uranium, potassium-argon, rubidium-strontium and so on.
