Page "Stephen Jay Gould" Paragraph 3

Most of Gould's empirical research was based on the land snail genera Poecilozonites and Cerion.

He also contributed to evolutionary developmental biology, and has received wide praise for his book Ontogeny and Phylogeny.

In evolutionary theory he opposed strict selectionism, sociobiology as applied to humans, and evolutionary psychology.

He campaigned against creationism and proposed that science and religion should be considered two distinct fields ( or " magisteria ") whose authorities do not overlap.
