Paragraph 1
Early risers
wake up early in the morning. Their
clock makes them do this while most of us are still in
sleep. Researchers said early risers could have
DNA from Neanderthals – our
from over 40,000 years ago. Neanderthals lived in
parts of Europe and Asia. They woke up earlier to gather food as the
rose. A researcher said it was better to have a
clock that could change to match the changing
of different seasons. He said a "faster" body clock makes people "more
to rise early".
