DNA barrier and genetic drift i believe they only allow for so much variance.
1. DNA barrier is a made up term
2. Genetic drift has nothing to do with what mutations can actually take place.
3. I dont care what you believe, id like what you can support with evidence.
Or become stronger. You can make a pretty compelling argument if you just leave out one half of the story...
This idea that traits somehow only get removed from a population is bullshit. Source please, source please!?!?!
Without a doubt, tigers and lions are well over 90% genetically identical. Because they all share common traits, because tigers and lions share a common ancestor. Do you honestly not think adaption could change an organism from a lion to a tiger? Theyre so similar they can interbreed still! They havent been separated long enough to become genetically different enough to not be able to interbreed.
Um what? Your use of the word recombination doesnt even make sense. We dont see "evidence" of recombination, we see the actual process. Sexual recombination takes place in every sex cell.
Where does a loss come in when your discussing recombination?
Your understanding of what recombination is is so convoluted i cant even follow your logic with this one. No one says when recombination can happen, genetic recombination happens each time your body produces a sex cell like a sperm or an egg....
What do you think you can see with a large gene pool like the mutt ? But in smaller groups that is where genetic drift is most powerful in eliminating traits creating breeds.
"The mutt"
O sorry, i didnt know that when we discussed a mutt we were talking about a specific genepool. I didnt realize there was a specific type of dog called 'mutt'.
What is your point? You never even discuss the central point of evolution!!! When genetic material is copied there are mistakes, maybe adenine turns to cytosine. This is how the function of proteins are altered, at least one of the ways.
Explain to me how there is no situation in which the altered expression of a protein is beneficial. Then explain to me what mechanism prevents these changes from building up.
Thats all you have to do. You have two questions to answer, get to it.
