I support adaptation, the species stays the same species even though it changes appearence. I would like to see some examples of what you are talking about when you say theres documented proof of a species naturally or by selection becoming a seperate species which can go on to reproduce.
In the case of a horse and donkey, a mule is infertile. even though horse and donkey are very similar species. Even in that case it does not support evolution. So im keen to see or hear what species ( which can reproduce) have been produced by men by selectively breeding another species. (Tampering with DNA not included.)
- Of course I don't. I simply asked whether you have a non-religious reason for doubting evolution. What could cause doubts strong enough for you to disagree with 99% of scientists?
Well the fact that they don't even agree among themselves as to how evolution occured would be a big one for me. I also have problems like i said with the theory of the big bang( send law of thermodynamics etc) Looking around at the complexity of earth to think it came from atoms exploding, creating an atmosphere to sustain life on a rock the right distance from the sun to support life.... theres alot more but theres a few
What do you mean by "the species stays the same"? How are you defining species? All biological characteristics are a result of genetics, not just those which affect appearance. If the genes responsible for appearance can change from one generation to the next, why can't the genes responsible for reproduction (or anything else)?
Selective breeding isn't (normally) what causes speciation, as in your mule example, though species have been created in this way (dogs breeds will likely eventually no longer be able to reproduce with one another). Speciation generally takes the form of a single species splitting into two (or more) after sub-groups become isolated from each other and adapt differently. If they're isolated for long enough, their genomes and phenotypes will become sufficiently different as to prevent the two groups reproducing together, and then they will continue to adapt independently and become more and more different over time.
An example of selective breeding creating separate species would be domesticated sheep. http://www.ncbi.nlm....les/PMC1690972/
Scientists might disagree on certain details, but not on the general principle of evolution. The same is true for almost all scientific theories. Disagreement on specifics doesn't invalidate the parts of the theory which are agreed upon - in the same way that two people can prefer different foods but it doesn't negate the fact they both enjoy some foods and need food to survive.
