Chimps and bonobos, Darwin didn't really know this, but chimps and bonobos mate one to four times per hour with up to a dozen males per day when they have their sexual swellings.
Čimpanze i bonobe, što Darwin nije znao, čimpanze i bonobe se pare do četiri puta po satu, s po tuce mužjaka dnevno kada dobiju seksualne otekline.
