Male kob an­te­lope, black grouse and those flies that swarm round your head when you stand still for too long in a field are lekking species. Males (it’s al­most al­ways the males, but see left) gather to­gether to dis­play their prow­ess to visiting fe­males, who queue up for the best per­form­ers. Dowdier males miss out en­tirely. Which raises a co­nun­drum: if only the sex­i­est males’ genes are passed on, why are there still unattrac­tive ones? The ‘lek para­dox’ re­mains to be solved.

Male black grouse raise their tails and in­flate their necks while dis­play­ing.
