July 24th, 2012 | Category: evolutionAs my patience for the Discovery Institute is at an all-time low, it’s heartening to see someone completely eviscerate their arguments. I mean, it happens all the time, but it’s particularly satisfying right now.
Carl Zimmer, well-known science writer, has been battling with DI fellow David Klinghoffer over the past few days over the evidence for a chromosome fusion event sometime in the evolutionary history of Homo sapiens that resulted in our chromosome 2, internal telomeres, double centromeric sequences and all. I say battling, but it’s been more [...]

June 25th, 2012 | Category: evolutionSometimes I get sidetracked from what I think are more important topics of discussion to things that are arguably less consequential. This is one of those times. So, instead of writing about convergent evolution, or intelligent design in Prometheus, today I’ll be touching on the “bioessentialist” views of James Barham, an atheistic, yet anti-naturalistic, blogger over at TheBestSchools.org.
Normally I wouldn’t bother engaging with a person so confused, but he’s now regularly mentioned by Evolution News & Views and Uncommon Descent, the two most popular pro-intelligent design blogs, so they at [...]

I think
[sketch]
Case must be that one generation then should be as many living as now. To do this & to have many species in same genus (as is) requires extinction. Thus between A & B immense gap of relation. C & B the finest gradation, B & D rather greater distinction. Thus genera would be formed. — bearing relation[...]
This is page 36 of Charles Darwin’s Notebook B: Transmutation of species (1837-1838), and of all of his publications, manuscripts and miscellaneous writings, this single page is, in [...]

January 6th, 2012 | Category: evolutionThe Carnival of Evolution for January is up at The EEB & Flow, a group blog about ecology and evolutionary biology. Some of the topics covered in this month’s posts are:
The Cambrian “explosion”! Was it as rapid as is claimed by some? Dinosaurs! Human evolution! Bat echolocation divergence! A potential new history of HIV’s relationship with human populations! And, of course, much, much more!
The next CoE, for February, will be hosted by… someone, I’m sure. Make sure you submit your evolution-themed blog posts [...]

December 8th, 2011 | Category: evolutionThe Carnival of Evolution for December is up at my good friend Psi’s blog The Ocelloid on the Scientific American blog network! As usual, it’s composed of a wondrous slew of posts on evolutionary biology and its many facets (including a post by yours truly). Some of the topics covered are:
The difference between population size and effective population size Gut microbiota influencing mating behaviour in flies Neutral networks Biological and ecological species concepts Symbiogenesis and the legacy of Lynn Margulis Quote-mining Charles Darwin Human evolution And, [...]

November 23rd, 2011 | Category: evolution educationSadly, it seems to be a pervasive trend in many countries to deemphasise the proper teaching of evolutionary biology. There are probably a few causes of this, ranging from anti-evolutionary pressure from religious traditions who dislike children being taught something that they feel denigrates their belief system, to unenthusiastic school boards and curriculum committees that, for whatever reason, come to the conclusion that evolution is not an important enough subject to teach students in detail. There are also numerous anti-evolution-education voices in the media (primarily in the US) that go [...]

April 6th, 2011 | Category: evolutionThe Carnival of Evolution for April is up at Quintessence of Dust! Head on over there for junk DNA, kin selection, brains, penises and archaea.
The next Carnival of Evolution (for May) will be at Lab Rat. There isn’t a host announced yet for June though, so put your name down if you’d like to host, and submit your evolution-themed posts as soon as humanly (and humanely) possible.

March 16th, 2011 | Category: evolutionKhalil is the manager of Student Voices, a Nature Education community blog to which I contribute (in fact, a new post of mine about hyperthermophiles should go up relatively soon, pending some editing on my end), and his first feature print article was recently published in the journal Significance. It’s all about testing the hypothesis of universal common ancestry – that all three taxonomic domains (Eukarya, Bacteria and Archaea) share a common ancestor – and it’s a great read if you’re interested in learning how biologists [...]
