E.6.2 Outline how natural
selection may act at the level
of the colony in the case of
social organisms
Natural Selection
Discusses mechanisms
of evolution
Involves the passing on of
genes
Natural Selection at the Colony
Level


Traits good for colony are passed on.
Traits bad for colony are prevented from
passing on.
Issues to Consider when
Discussing Natural Selection
in Social Organizations

Specialization of roles

“Super organism”
Issues cont.

Two views in regards to this:

Level of natural selection is that of the
colony with the “fittest” colonies surviving
