Natural Curiosities

Saade Dokumentaal

Davis presents parthenogenesis, asexual reproduction, notably in species which are capable of sexual breeding too. Sometimes it's the way for a population to be established by a single colonizing female, as Komodo dragons did on various smaller Insulind islands. Sometimes cloning is deemed ideal for a species perfectly adapted to its environment, albeit a gamble on the long run to give up natural variation. Often however it's combined with sexual reproduction in a complex seasonal s-cycle, as with aphids, whose females also breed pregnant offspring, so as to clone themselves fast in huge numbers.
