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.

Answer 2- Present-day species developed from earlier, different species.

Explanation:

Animals and plants today have roots in species from long ago. The wooly mammoth was the ancestor of the modern day elephant.

idk im sorry.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
