Research and writings

In the early 1950s, Lever started research on the neuroendocrine system of the basommatophoran snail, ''
Lymnaea stagnalis ''Lymnaea stagnalis'', common name, better known as the great pond snail, is a species of large air-breathing freshwater snail, an Aquatic animal, aquatic pulmonate gastropod mollusk in the family (biology), family Lymnaeidae. The great pond sn ...
''. Lever himself found a particular kind of neurons in the ancylid snail ''Ferrissia'', and his student Joos Joosse demonstrated those neurons in other snail species. ''Lymnaea'' became the animal of choice for physiological research at the VU Amsterdam laboratory for decades. At the beginning of his career, Lever’s ideas about evolution and the species concept were inspired by the

, who had published about Dooyeweerd's approach in the domain of biology in the 1930s. Diemer was a great influence on Lever's thought. Together with Dooyeweerd, Lever wrote four articles about the species concept in the journal '' Philosophia Reformata'' (1948–1950) in which species were defined as constant types. In his book, ''Creatie en Evolutie'' (1956), Lever still subscribed to Dooyeweerd’s philosophy but also suggested that it is possible that biological evolution occurred. Later he moved away from these earlier ideas about species constancy, and adhered to a kind of
