HELP PLEASE I ONLY HAVE TEN MINUTES
Before the invention of the lightbull Americans burned oil in lamps for light. Whale oil was a popular biofuel for these lamps. Ship crews would hunt whales for their oil. They searched for the largest whales they could find so
that they could obtain as much whale oil as possible. How might decades of whale hunting possibly affect the natural selection of the species?
The whales lost their legs
The whales became slower
The whales became smaller
O The whales changed their calls.
