- contains genes, DNA, factors
- agrees with cognitive approach with internal processes

What is the definition of evolution?
net directional change in the chartacteristics of organisms or populations over many genetics.
What are the three studies involved in the approach?
- twin studies
-family studies - adoption studies
What does the twin studies involve?
-psychologists use twin studies to investigate the genetic basis of behaviour.
-monozygotic - identical twins
-dizygotic - non-identical twins
What are concordance rates?
The extent of which a pair of twins share similar rates or characteristics.
there should be a 100%rate between monozygotic twins.
What are family studies?
1869 - Francis galton
