How does molecular
biology provide
evidence of evolution?
• All living things are generally the same in the
way that they are built
• They all begin as single cells that reproduce
• They come to a certain life span and get old
and die
• All plants and animals inherit genes from their
parents
• Hemoglobin and Myoglobin are found in
almost every multi-celled animal
• All living things are made up of
only 20 kinds of amino acids
• The DNA language in each and
every living thing is the same.
Four different
molecules that support
the theory of evolution
Myoglobin and Hemoglobin
• Found in mammals, birds, reptiles,
amphibians, fish, worms, and
mollescs.
Cytochrome
• A protein that is involved in
energy transfer and its changes
are very slow
Fibrinopeptides
• Involved in blood clotting and its
changes are very fast
