Nothing you've said contradicts anything in my original statement.
Then you weren't paying attention. You claimed:
crows have displayed an ability to use tools that goes beyond what has been observed in other animals.
And I said I doubt it. Look at these monkeys making spears to hunt with.
And you said:
Apes use one tool to aquire food. Not only can crows create tools (as we have shown), but they can also manipulate several different tools in order to gain food.
I then told you apes don't use just one tool to aquire food.
Here's an article. And another.So you gave us a crow that can use the different tools it's given for different purposes.
Crows: Different length sticks. Can also bend sticks.
Chimps: Spears, hammers, drills, pounders, enlargers, collectors, perforators and swabbers.
And you want us to believe that crows have gone beyond what has been observed in other animals? That's prime failsteak.
Sorry, but you can't pick and choose when speculation is and isn't acceptable.
I can. One uses a reasonable comparison of brain size in comparable species to infer comparable intelligence and skills.
The other uses... wishful thinking?
Insisting it doesn't is no better. The difference is, we've provided evidence to back up our theory. You haven't.
No. No you haven't. Pretending you have is even worse. How dull.
What do you mean "if they were left ling enough"? The link YOU provided says that it takes less than a hundred years for wood to petrify. Now, correct me if I'm wrong, but I'm pretty sure the classical era began well over 2,000 years ago. You know, B.C., before cornflakes. Why would they need to be there any longer?
Oh dear lord.
The petrified wood that we find today
was petrified relatively quickly. However they were petrified millions of years ago. It's all about the conditions they find themselves in, the chemicals in the ground necessary to create petrification. Volcanic ash is supposed to be good.
Wood is preserved by denying bacteria, oxygen and disturbance. It is then petrified by silicates. If the silicates are in abundance as was the case millions of years ago, then the process can be quick. If not, then it'll take longer.
Strangely, the same conditions that would be preserving wood at the time of the dinosaurs would also be preserving boats. Hmm.
