in species
Evolution
gradual development
of something
Natural Selection
the "selection"
of traits that may
help increase a
species'
survival and
their ability to
reproduce
Variation
differences
among the
genomes of
members of
the same
species
Adaptation
a body part or feature or a
behavior that helps a living
thing function better in its
environment
Mutation
a change that
occurs in our
DNA
sequence
Embryo
the early stage
of development
of a
multicellular
organism
Homologous Structure
similar
physical
features in
organisms
that share a
common ancestor, but the
features serve completely
different functions
Analogous Structure
features of different species
that are similar in function
but not necessarily in
structure
Vestigial Structure
a structure in an
organism that
has lost all or
most of its
original function
in the course of
evolution
