The Tangled Tree, by science writer David Quammen, is excellent. He has researched the discovery and exploration of horizontal gene transfer (HGT) very deeply, and his writing kept us engaged. We especially enjoyed closeup looks at dozens of scientists whose work we know, including W. Ford Doolittle, George Fox, and the principal character, Carl Woese. Quammen's colorful anecdotes and pithy descriptions only made it better. For those wanting more still, there are some 75 pages of endnotes, bibliography and indexing.
Finally, we are quite pleased that HGT gets the recognition it should. Quammen mentions lots of supporting evidence, as we do here. But we first came to HGT from the opposite direction — skepticism. We wanted to know where new genetic programs come from. The standard Darwinian answer seemed unsupported and implausible. We concluded that new genetic programs must be somehow supplied in an open system.
That paradigm shift, we now realize, is way too big to swallow whole. For now, we welcome the major advance that Quammen makes clear – the importance of HGT in evolution – and the future it may portend.The Tangled Tree: A Radical New History of Life by David Quammen, Simon & Schuster, ISBN 9781476776620, August 2018; reviewed by John Archibald, Nature, 31 Jul 2018.

Science writer Elizabeth Pennisi makes these observations in an illustrated review (example, right) concerning the evolution of multicelularity. Several respected research teams conclude that multicellularity must have evolved easily, because many of the needed genes were already installed in single-celled species. ...much of the molecular equipment needed for cells to band together and coordinate their activities may have been in place well before multicellularity evolved.
What functions the genes for multicellular features may have provided in one-celled species is uncertain, but, by darwinian logic, they must have done something. Else, the genes would not have been composed, nor preserved. Darwinists are adept at dealing with surprises, and indeed, former functions are suggested for several of these genes.
Our perspective is altogether different, because genes that are available before deployment are a logical requirement in cosmic ancestry. Examples are accumulating.The power of many by Elizabeth Pennisi, Science, 29 Jun 2018.
