I made no wild claims and what claims I did make I backed up far better than this:
“I find it more lkely that we are descended from ancestors that had a better sense of smell than that we are the ancestors of people with a better sense of smell.”
Ignorance of the function of some of genes in the olfactory system is a poor reason to assume evolution to be fact.
But as you will.
Remember my example of your computer?
That's true, but the similatities and differences in genes form a nested hierarchy, which just one of dozens of lines of evidence supporting evolution.
Meanwhile, mainstream science continues to look for functions, even while I doubt that much will be found.
Not much rides on my being correct or wrong about this.
