D. Olduvai Gorge
Explanation:
- From 1935 to 1959, Louis and Mary worked hard in several excavations in Kenya and Tanzania, looking for the remains of early humans. Although they encountered many difficulties, both because of the dangerous and inaccessible terrain and the scarce postwar scientific foundations.
- However, the real breakthrough came in 1959, when one morning in the Olduvai Gorge - a region separating the famous National Park from Tanzania's more famous Serengeti National Park - Mary discovered a 1.75 million-year-old hominid skull, later classified as Parantropus boisei.
- This finding was a strong argument that hominids evolved in Africa.

Otter attacks on humans are rare. Prophylactic antibiotic therapy after an animal bite is indicated for clinically significant injuries and a weakened immune response. '
The otter's main barrier against heat loss is an airtight barrier. The otter vigorously rubs its paws together to seal the air next to its skin. It can also breathe air through its fur. Underwater, they look silver because of the oxygen in Turkey. Sea otters swim on their backs when they sleep.
They can wrap themselves in seaweed or hold each other's hands while they sleep to stay there and float out to sea. Sea otters have three main strategies to escape from predators: run, hide in the kelp where they live, or surface. They can also use their powerful teeth when they encounter other sea otters.
