FRAGMENT FROM NATURE continues the meditation on nature’s connectivity from a remarkable essay by Bill Graham, a former marine biologist. As a scientist, he has not only made his own observations and gathered those of others together, but has formulated some general principles about interconnectivity. I hope that you enjoy this as much as I have. View in LinkedIn

That is, frequent recombination should result in conflicting molecular phylogenies for genes in conspecific organisms.” https://lnkd.in/djKBnru View in LinkedIn

BUSH NOT TREE. “A study of conserved loci in bacterial pathogens, conclude for lineages within a species that “over the long term, the impact of relatively frequent recombination is to obliterate the phylogenetic signal in gene trees such that the relationships between major lineages of many bacterial species should be depicted as a network rather than a tree.” https://lnkd.in/djKBnru View in LinkedIn
