I was challenging your assertion that the sole line of evidence for evolution is extrapolation from the fact that so-called microevolution takes place. If the common designer hypothesis is the more compelling interpretation of the evidence than the common ancestor hypothesis, then show how. Also, what observations would falsify the common designer hypothesis.Gman wrote:No they do not all share a common ancestor.. That is an assumption based on micro-evolution and a few "so called" fossil links.. What they really reveal is a common designer..touchingcloth wrote: Your argument might be more compelling if the consensus of science was "small scale change happens. In light of this, all organisms must share a common ancestor". You ignore the fact that there are multiple lines of evidence that support evolution.
Also evolution has never been seen to create any new information. It can resemble the information a bit via natural selection, but not create anything new..
And evolution has been seen to create new information - genotypes and phenotypes.
I'm still confused over where you'd place the boundary between micro and macro. Taking an example - assume for a moment that birds really did evolve from dinosaur ancestors. If the transition happened in baby steps, then when would you say that macroevolution had occurred? I imagine that the differences between any given dinosaur and its offspring you would call microevolution, likewise between any bird and its parent. So where would you place the line?Gman wrote:Microevolution deals with changes in the gene pool of a single population. Macroevoution simply “considers” broad patterns of evolutionary change over long periods of time and includes the origin of new groups. But considering micro-evolution doesn't necessarily mean that it will lead to macroevolution or the creation on new species.
Nope. Just curious as to what definition of the term species you would go with.Gman wrote:Are you referring to the fruit fly experiment or debacle? Or perhaps in plants?touchingcloth wrote:As a related question, is there a working definition for "species" that you are aware of that can classify every extant, extinct and potentially unknown creature into distinct categories?
Again that's a question of statistics and modelling, isn't it? Given a set of similarities and differences and known methods of inheritance, does a common ancestor followed by mutations or multiple populations with separate origins fit the data best?Gman wrote:Again that could also fall into a common designer technique as well.. What about HARs? Some of them are very different in humans than in chimps...touchingcloth wrote:Also the question of whether or not every creature was the product of a separate creation rather than a common ancestry is a good test for evolution. I'd imagine that there are statistical techniques able to assign a likelihood to the probability of, say, protein sequences between 2 species being the product of common ancestry vs separate ancestry.
