God screwed up the human eye. That's why we have blind spots in our
eyes, where the optic nerve plunges through the retina towards the brain.
There's a 'better' way to do it - as in squid, connect the optic nerve
endings to the retinal cells BEHIND them, instead of between them and the
incoming light. Proof positive that God exists and is not terribly

Back to the unfortunately-ignored question about Hot Topics in Evolution
The evolution of sex (outcrossing with recombination) is still as hot
and unsolved as ever. Hamilton and Kondrashov have recently contributed
clear treatments of some competing hypotheses, namely that sex serves to
(1) allow organisms to quickly adapt to their rapidly-evolving parasites
and (2) that sex is an efficient way of eliminating rapidly-accumulating
moderately deleterious mutations.
For a pleasantly confusing afternoon, discuss the population genetics of
transposable elements as they come to terms with their unwilling host
genomes - these sequences have evolved in numerous clever ways to spread
without causing too much harm to their hosts. Similar games are played
by other bits of selfish DNA, as well as viruses and other pathogens.
