I know that even in saying all this I'm up against your assumption that mutation is going on all the time and IS contributing to the construction of new varieties. I do believe that is just an assumption, that the reality is that phenotypes require the elimination of alleles for other phenotypes. Maybe some of the alleles in the new phenotype were originally mutations, that could be, but when a new population is coming to be characterized by this phenotype it can only happen by leaving behind competing alleles, mutation-originated or not.
​
If I understand the implication of what you are saying, perhaps assumptions such as these are why more evidences of a greater abundance and variety of transitional fossils are not observed.

........but when we look at the bewildering variety of life on this planet that is not what we see. We only see it in species that are on the brink of extinction, and I am not saying that there are not a lot of them, because in the Human era there are.
​
Isn't this bordering on circular reasoning, Tanypterix, interpreting observation of the bewildering variety of life as evidence for evolution, evolution being the assumed agent of bewildering variety, given the aggregate biodiversity of species is declining?
