Before the girl and the boy tie the knot, they feel like falling in love. And most of them do. Cupid works. Biology demands. And, sociology warrants.

Before you can ask 'Is Darwinian theory correct or not?', You have to ask the preliminary question 'Is it clear enough so that it could be correct?'. That's a very different question. One of my prevailing doctrines about Darwinian theory is 'Man, that thing is just a mess. It's like looking into a room full of smoke.' Nothing in the theory is precisely, clearly, carefully defined or delineated. It lacks all the rigor one expects from mathematical physics, and mathematical physics lacks all the rigor one expects from mathematics. So we're talking about a gradual descent down the level of intelligibility until we reach evolutionary biology.

Belief begins where science leaves off and ends where science begins.

Biochemists assume that the three cellular kingdoms evolved from a single common ancestor, because the alternative of supposing an independent origin of life two or more times presents still greater difficulties. The common ancestor is merely hypothetical, as are the numerous transitional intermediate forms that would have to connect such enormously different groups to the ancestor. From a Darwinist viewpoint all these hypothetical creatures are a logical necessity, but there is no empirical confirmation that they existed.

Biogeography typically trumps taxonomy and anticipates molecular phylogeny

— Dennis McCarthy

Biological databases impose particular limitations on how biological objects can be related to one another. In other words, the structure of a database predetermines the sorts of biological relationships that can be 'discovered'. To use the language of Bowler and Star, the database 'torques,' or twists, objects into particular conformations with respect to one another. The creation of a database generates a particular and rigid structure of relationships between biological objects, and these relationships guide biologists in thinking about how living systems work. The evolution of Gen Bank from flat-file too relational to federated database paralleled biologists' moves from gene-centric to alignment-centric to multielement views of biological action.

Biologically speaking, you are the child of Mother Nature, and neurologically speaking, you are the heirs of immortal bliss.

Biologists will teach us that the survival of the species depends on cooperation, not competition.

Biology is destiny only for girls.

Biology is run by intricate cellular mechanisms. Cellular mechanisms are run by Nature. Thus, the more we attempt to understand Nature, the more we get closer to our existential properties.
