How can scientists determine that the tooth is that old? The giant platypus may not have become extinct - just modified itself to the environment over millions of years. As the climate has changed - perhaps the teeth became unnecessary due to a change in diet which was needed for survival.

50K years. I stand corrected. (I thought it was 20K)

the article explicitly states the current platypus is not a descendant of this one. So they must have had a common ancestor.

They usually date fossils by carbon dating something in the same layer of rock.

I think it is very odd that someone who doesn't want his science topic tarnished by religious commentary is always the one to bring it up. :roll: :roll: :roll:

I don't recall taking that position.

Understanding the universe is a path to enlightenment.

I wish the promises of religion and eternal life were true. Religion fought a war with science until the evidence could not be hushed up. I consider its days are numbered. Not replaced by science but only has a place in the minds of those who cannot handle the reality we are not special and are just smart animals where each individual is in signification in space and time.

Short memory... maybe if you start back at the beginning they might still be there. :c

Oh I thought it was funny... if I was a bible basher though, of any persuasion, it would be offensive.
Like I said, you have been the one not wanting religion brought up here... which in my opinion is fair enough.
