But truly, this assertion of multiple episodes of abiogenesis or biogenesis opens the door to exactly such a thing simply because it makes the evolutionary tree of life not a continuum after all.
Jeepers...
Bizarre isn't the word.
But the multiple episodes of abiogenesis or biogenesis are not yet documented by science. Where we see this hypothesis is from the creation "science" websites, under the heading of baraminology.
To repeat and expand this somewhat further, the Darwinian macroevolution model is represented by a single tree of relationships, every form of life being related to every other form of life... In the baraminic model there is a forest of trees without connecting roots... One of these rootless trees would have branches representing only human diversification, another for canids, another for felids, etc. Source.Creationists routinely trash the theory of evolution because it does not include an origin theory, such as the biological theory of abogenesis. It seems like you are willing to accept multiple origins, as does baraminology?
