Diversity
Simpson's Index (D)
lower the value of D (closer
to 0), greater diversity
EQUATION
Simpson's Index of
Diversity (1-D)
greater the value of D,
greater sample diversity
EQUATION
- n = total number of organisms
of a particular species
- N = total number of organisms
of all species

have same origin as evolved
independently
example -
- wings of bird + insects
- piercing + sucking
bugs/mosquitoes
-
-
Homologous Structures
D: structures that DO have
the same origin
same biological structure and
position, but maybe not same
function
examples -
- human arm
- dog foreleg
- bird wing
