Scientists at Penn State have sequenced the
DNA of the extinct woolly mammoth. The data
suggested that the woolly mammoth was more
closely related to present-day elephants than
previously believed.
Which statement could account for the
similarities between the woolly mammoth and
present-day elephants?
(1) Common gene mutations were caused by
agents such as industrial chemicals and
radiation.
(2) Present-day species developed from earlier,
different species.
(3) Selective breeding results in offspring better
able to survive.
(4) Both animals have identical genetic
information.
