Systematics and Biogeography blog 23 Oct 2007 The estimable Drs David Williams and Malte Ebach have started a blog on Systematics and Biogeography, which supports a recent book they haven’t sent me a free copy of yet. Expect much puncturing of pretensions and orthodoxies. Book Ecology and Biodiversity Evolution Species and systematics
Ecology and Biodiversity Virulence and vectors 18 Mar 202018 Mar 2020 Apropos of nothing, I am reminded of Paul Ewald’s book Evolution of infectious disease (1994). Ewald begins with the question of whether parasites and pathogens evolve towards commensuality (the state of being mutually beneficial, which is what, among others, Macfarlane Burnet thought, along with many immunologists and epidemiologists. Ewald points out… Read More
Ecology and Biodiversity Darwin was wrong…ish 23 Jan 200918 Sep 2017 There’s been a slew of “Darwin was wrong” and “Evolution is more complicated” stories in the media lately. It’s nearing Darwin day so simple minded media hacks can be explained as needing to find the requisite “drama” in their “stories”. But the real picture is a lot more nuanced, and… Read More

Read through the posted link. Very interesting. Having been an aspiring paleontologist up throught the MS, I think this business of dating lineages based on fossils is pretty scary. Fortunately the group I have done the most systematic work on, the family Rivulidae of the Aplocheiloid killifishes, have, so far as I know, no fossil representatives. There have been two independent DNA trees done for the Aplocheiloids, and they are similar enought that we might actually know something. When relationships and distributions are compared to continental drift maps, one feels pretty confident as to what the vicariant events were. So we can date the vicariant events based on geological, but nonfossil, information. We have revised one Rivulid genus based on DNA. The sequence of speciation events and the geological history of that part of South America correlate very nicely. Talking around, workers in other fish groups are coming up with the same sort of scenario. If all this is so, the modern bony fishes originated earlier than we have thought, and diversification was rapid early on.
