As those who study evolution noted:
"
John Archibald of
Dalhousie University in his book
One Plus One Equals One (2014) finding common ground with Koonin notes,
“the tree of life has come upon hard times… [with] the “overall picture emerging is one of mosaicism” – not one of evolutionary changes of “one species… taken and modified” into a new species."
Amazingly,
David Baum and
Stacey Smith in the book
Tree Thinking, an Introduction to Phylogenetic Biology (2013) pushes the envelope further arguing that “Our knowledge of molecular process is not good enough to definitively rule out independent origins.”
So you take away all the die-hard fanaticism out of the evolutionary PR and you are left with the facts that we simply can't rule out independent origins and a ancestry of mosaicism that does not point to one species.... taken and modified into a new species....
And hence the tree of life is withering, being replaced by the radiation scheme.
“The genomic revolution [has]… effectively overturned the central metaphor of evolutionary biology, the Tree of Life,“ argues
Eugene V. Koonin of the
National Center for Biotechnology Information in his book
The Logic of Chance.
However, the revision has the same problems as Darwin’s tree – no original ancestor and no transitional links. Because there were no transitional links, merely new variation of the same species through mating.
