Rotaria
Rotaria
is
a genus
of
asexual
microorganism
known as a
bdelloid rotifer
.
Analysis
published
in
2007
of
morphology
and
DNA sequence
data
of
species
form the
genus
confirmed
that
despite
their asexual
mechanism
of
reproduction
, two
fundamental
properties of species,
independent evolution
and
ecological
divergence by
natural selection
occurred. This
demonstrates
that
sex
is not a
necessary condition
for speciation.
