EVOLUTION
The Beagle
Ship on which Darwin
was a naturalist
Charles Darwin
Person who first
described evolution
Evolution
Change over many generations
Natural Selection
The most fit individuals are
more likely to survive and
pass their genes to their
offspring
Speciation
Formation of a new
species
Gene Pool
Combined genetic
information of all
members of a
population
Homologous
Structures
Structures that are
similar in shape
Vestigial Structures
Structures that have no function
in present organisms but had a
function in past organisms
Fossil
Trace of an organism from
long ago
Punctuated
Equilibrium
Long periods of little
evolutionary change with
spurts of rapid change
