Does an isolated population mean a small population? If so, does the DNA of the individuals in that small population matter?No, they begin with an isolated population. I'm not sure the size matters.
You mean other than being larger?so the nervous system of critters like the mouse are fundamentally different than their Cretaceous ancestors?
Not necessarily. A population could be isolated on the continent of Australia or South America for example.Does an isolated population mean a small population?
The population is the individuals. The importance of any DNA is its percent of the population's DNA.If so, does the DNA of the individuals in that small population matter?
Are you assuming/guessing or do you know that from fossil evidence?You mean other than being larger?
Sounds like you are still talking about slight successive changes. How would your example of a long period of stasis followed by an abrupt change work on that isolated species on Australia? Because that's really my issue with your belief that individual DNA isn't important.Not necessarily. A population could be isolated on the continent of Australia or South America for example.
Again... you are addressing slight successive changes leading to new species. You aren't really addressing abrupt changes. Do you believe DNA of individuals aren't important when a new species arises abruptly?The population is the individuals. The importance of any DNA is its percent of the population's DNA.
Not sure what the basis was for that statement. I would assume fossil evidence. I read about it in a talk about the evolution of intelligence. It made perfect sense to me because I see increasing complexity in the tree of life. Unlike you I don't believe intelligence evolving was random or an accident. I see it as an eventual outcome because beings that know and create are possible under the laws of nature and because it's logical for intelligence to evolve and continue to evolve because it's logical because intelligence is a functional advantage which aids survival and the flourishing of a species.Are you assuming/guessing or do you know that from fossil evidence?

I think our definitions of 'abruptly' are wildly different. If you think in human terms, only viruses and bacteria can possibly generate a new species in an 'abrupt' timeframe. I don't know that even they can do it with their multiple generations in a single day. For most species, 'abrupt' change means geologic time, plenty of time for a thousand or more generations.Again... you are addressing slight successive changes leading to new species.

Sorry but I just don't agree.Not sure what the basis was for that statement. I would assume fossil evidence. I read about it in a talk about the evolution of intelligence.

That makes no sense.Maybe it was lost on you that the Darwin award was awarded to stupid people who Darwinized themselves out of existence.
The norm is long periods of stasis with abrupt changes. So, no, for most species 'abrupt' change does not mean geologic time.I think our definitions of 'abruptly' are wildly different.

Then you have never heard of the Darwin awards.Sorry but I just don't agree.
That makes no sense.
I have but that doesn't mean your comment made any sense.Then you have never heard of the Darwin awards.
The Darwin awards are given to stupid people who died doing dumb things, right?I have but that doesn't mean your comment made any sense.
How much time does 'abrupt' change take then? Years or generations will do.The norm is long periods of stasis with abrupt changes. So, no, for most species 'abrupt' change does not mean geologic time.
Yes.The Darwin awards are given to stupid people who died doing dumb things, right?
One generation.How much time does 'abrupt' change take then? Years or generations will do.
So how is that not an example of intelligence is a functional advantage that aids survival since lack of intelligence leads to demise?Yes.
Not a chance. If that were so why don't we see it happen?One generation.
What evolution have you seen?Not a chance. If that were so why don't we see it happen?
