Ancient Humans Ate Cantaloupe-Size Eggs from 500-Pound Birds

The burnt eggshell fragments of an ancient giant bird have helped scientists solve a 50,000-year-old whodunit in Australia. Before humans arrived in Australia about 50,000 years ago, these flightless birds lived across much of the continent. Now, evidence of human-scorched eggshells suggests that the new arrivals were cooking up the eggs for supper, likely putting a large dent in the birds' reproductive success, a new study shows.
