Bonnet, Charles (1720-1793)
Swiss naturalist who discovered that aphids could reproduce parthogenically (female eggs do not require the sperm for fertilization). He also noted that the freshwater hydra would regenerate lost parts. Bonnet speculated that aphid eggs consisted of an infinite number of smaller eggs, one inside the other, and generalized this preformation theory, which maintains that a child arises from an adult in miniature contained within the egg, to all other animals.

Camerarius, Rudolph Jakob (1665-1721)
Demonstrated experimentally the sexuality of plants in Epistolae de Sexu Plantarum (Letter on the Sexuality of Plants) (1694), in which he identified the stamen and pistil as the male and female organs, and the pollen as the fertilizing agent. [eng]
