Prehistoric cultures were hunting whales at least 3,000 years ago
Recent findings by a Russian-American research team suggest that prehistoric cultures were hunting whales at least 3,000 years ago, 1,000 years earlier than was previously known.
Early whales gave birth - and probably rested and mated - on land, according to a study published on Wednesday that examined 47.5 million-year-old fossils discovered in Pakistan.
