Darwin’s Fish: Evolutionary controversies in the fossil record | University of Oxford Podcasts – Audio and Video Lectures

Great lecture by Matt Friedman on Darwin’s (and others’) discoveries about evolution and genetics, symmetry in fish, and other things.

Edit: I have since discovered Friedman, M. has written numerous papers on teleost fish, whilst writing my own essays. A very clever man.

More ancient viruses lurk in our DNA than we thought — ScienceDaily

We all know that mtDNA isn’t human in origin and was probably originally an assimilated bacteria (chloroplasts in plants being the result of a similar evolutionary occurrence of engulfed cyanobacterium), but apparently there’s more.

“In fact, about 8 percent of what we think of as our “human” DNA actually came from viruses. In some cases, HERV sequences have been adopted by the human body to serve a useful purpose, such as one that helps pregnant women’s bodies build a cell layer around a developing fetus to protect it from toxins in the mother’s blood.”
