The Colin Leslie Dean species paradoxModerator: BioTeam Re: The Colin Leslie Dean species paradoxIf this thread is going nowhere, why not just lock it? I think all the points refuting the paradox have been stated by now. Or just ban gamila, that would work too.
Science rules!

Re: The Colin Leslie Dean species paradoxTell me how you define exactly what the first bird was, how you distinguish it from the bird-like organisms it evolved from. There is no exact point at which the first bird existed. From a common ancestor, the species gradually became more bird-like until we have the birds we know today. But that took millions years to go through, so no one can see exactly where one ancetor starts and another begins.
If you insist though, the first "bird" we know today probably mated with an extremely bird-like species that was not exactly like todays but very similar. Similar enough for the bird to mate with. Science rules!

then the bird and bird- like species must have been the same species as we are told that only the same species can mate and have fertile off spring 1) if they are diferent species they cant mate if different species can mate then the definition of species ends in contradiction and is meaningless nonsense 2) if theyare the same species then we have point two of deans paradox
Re: The Colin Leslie Dean species paradoxOkay, rephrasing: Bird-like animals gradually gained different traits until today's birds. At any specific time, though, all bird-like animals would be the same species.

bird-like is not the same thing as bird being bird -like means they where not birds yet sorry there where birds long before birds of today so what what if all bird- like animals- where the same species what the question is so what did the first bird mate with
Re: The Colin Leslie Dean species paradox
A better response is that there was no "first bird." Populations evolve not individuals. I have told gamila this over and over, but he ignores me like everyone else. P.S. Don't waste anymore time on him.
populations are made up f individuals if the individuls dont evovle neither does the population so is a population made up of 2 or 10 or 10 million individuals then we are left with option 2 so that means 10 million somethings all changed into 10million birds simulateously ie at the same time
Re: The Colin Leslie Dean species paradoxMono-regional theory leads to a paradox, and muli-regional - not leads. Here's an example:

Re:
Could it be you are almost there? Yes, the population could be made up of millions of individuals, or more often, thousands or hundreds of individuals. Individuals reproduce, but populations evolve. Evolution is a change in gene frequency over time... individuals do not change in gene frequency, that is why they do not evolve. The size of the population does not preclude evolution. If a gene confers a benefit to fitness, it will increase in the population... this is simple statistics. Studies have shown even a small benefit is sufficient. Thus, there does not need to be multiple mutations all at the same time. One is enough, assuming a mutation is part of the preocess, which is not even necessary. This is where you may have been misinformed... mutations are not required for a given speciation event, though they may be invovled. I told you before that polygenic traits can vary widely without any new mutations, but you continue to ignore me. Do some research on population genetics.
