Sociobiology is not just any statement that biology, genetics, and evolutionary theory have something to do with human behavior. Sociobiology is a specific theory about the nature of genetic and evolutionary input into human behavior. It rests upon the view that natural selection is a virtually omnipotent architect, constructing organisms part by part as best solutions to problems of life in local environments. It fragments organisms into 'traits,' explains their existence as a set of best solutions, and argues that each trait is a product of natural selection operating 'for' the form or behavior in question. Applied to humans, it must view specific behaviors (not just general potentials) as adaptations built by natural selection and rooted in genetic determinants, for natural selection is a theory of genetic change. Thus, we are presented with unproved and unprovable speculations about the adaptive and genetic basis of specific human behaviors: why some (or all) people are aggressive, xenophobic, religious, acquisitive, or homosexual.

About this quote

What does it mean?
Sociobiology claims natural selection builds every human trait as a best solution, often without proof or testability.
In plain terms
This theory says natural selection designed every human behavior perfectly, but many claims are untestable guesses.
What can you take from it?
Treat claims that every trait is an adaptation with skepticism until evidence supports them.

Where it applies

  • theory critique
  • genetics research
  • evolutionary biology

Putting it to work

  • evaluating adaptationist stories
  • teaching scientific method

Questions to consider

  • Which behavioral traits lack evidence of adaptation?
  • How do we test if a behavior is selected?

Another view

Natural selection does shape traits, so skepticism should not become denial.
