Evolutionary relationships are determined
on the basis of similarities in structure,
breeding behavior, geographic distribution,
chromosomes and biochemistry. Because
these characteristics provide
the clues about how species
evolved, they also revel
the probable evolutionary
relationships of species
Species that share a common ancestor also
share an evolutionary history. The
evolutionary history of a species is called
is phylogeny.
One biological
system of
classification that is
based on phylogeny
is cladistics.
A cladogram is a
model of the phylogeny
of a species and is
similar to a pedigree or
family tree.

The diagram below is known as a fan diagram.
Groups of organisms in the same colored ray
share more inherited characteristics.
Base your answers to the following questions on the diagram below
and on your knowledge of biology. Letters A through E represent
different species of organisms. The arrows represent long periods of
geologic time.
Which species would most likely show the
greatest similarities in their amino acid
sequences?
Base your answers to the following questions on the diagram below
and on your knowledge of biology. Letters A through E represent
different species of organisms. The arrows represent long periods of
geologic time.
Which species is the common ancestor to all of
the other species?
Base your answers to the following questions on the diagram below
and on your knowledge of biology. Letters A through E represent
different species of organisms. The arrows represent long periods of
geologic time.
Were not able to adapt to their environment  natural selection
What happened to species C, D & E? What
might have caused this to happen?
