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 [...]

October 10th, 2011 | Category: evolutionThe Carnival of Evolution for October is up at EvoEcoLab on the Scientific American blog network! There’s heaps of great stuff over there this month, including book reviews, limb evolution, jawless fish, creationism, hitchhiking genes, crocodile fossils, and co-evolution. You know you love it – go check it out.
The next CoE, for November, will be hosted by The Mermaid’s Tale - submit your evolution-themed blog posts here.

July 10th, 2011 | Category: evolutionThe Carnival of Evolution for July is up at The Lessons of Evolution! The author, Will, is a 13 year-old budding evolutionary biologist: just what I like to see! So, make sure you head over and check out the great selection of blog posts he’s got over there, including posts on fly ejaculate, deadly E. coli, evolutionary trees, digital organisms and more!
The next CoE, for August, will be hosted by Larry Moran over at Sandwalk - submit your evolution-themed blog posts to l(dot)moran(at)utoronto(dot)ca.

April 7th, 2011 | Category: biologyEveryone does eventually, and when they do, the International Society for the Study of Origins of Life will be there for them – with 214 pages of abstracts (PDF) from their 2008 symposium.
It’s a fascinating read for those interested in current abiogenesis hypotheses and models, but be warned: you’ll need to search for keywords of interest (like “ribozyme” or “hydrothermal”) if you want to move around the document quickly, there’s just too much in there!
Hat-tip to Cassandra’s Tears for forcing me to happily [...]

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.

April 1st, 2011 | Category: biologyOver on Student Voices, my latest blog post has been published, entitled Some Like It Very, Very Hot. It’s all about the crazy world of hyperthermophiles – organisms that can comfortably live in temperatures exceeding 60ºC – and some of the current record-breakers in the field: Pyrococcus furiosus, Geogemma barossii and Methanopyrus kandleri. There are few things more fascinating than these microbes, people, and their extreme biology continues to astound the scientific community.
Here’s a little taste:
To put these hyperthermophiles’ biochemical achievements in perspective, proteins in our [...]

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 [...]

Homologous Legs is the blog of Jack Scanlan, an Australian biology student who has a serious problem with creationists, intelligent design proponents and anyone else who misrepresents evolutionary biology or science in general.
He uses this blog to post news about the intelligent design/evolution "war", science communication in biology and chemistry, and mostly coherent thoughts from his scattered, music-loving brain. Contact
