There’s a range and always has been, with these vessels.
Survival will no longer be an issue because almost all of us have passed the subsistence level of income. Therefore, the weeding out of disadvantageous mutations, and the expansion of advantageous mutations no longer works. Almost all humans live to reproduction age and there is a concern for increasing numbers of congenital disorders since survival of the fittest is gone as a check on the same.
Having said this, new species have emerged in abundance soon after extinction events, such as the one that wiped out the dinosaurs. In the space of a few million years, many new species emerge from whatever traces of life that survived. The renewal of life with great diversity is more like a miracle than the workings of the accumulation of small mutations that eventually differentiate one from another species.
New species, but no intermediates?
That defies the entire premise that your ideology is based on. Evolution must show gradual improvement, not exponential or astronomical changes.
Baloney.
