Throughout recorded history, humans have reigned unchallenged as Earth’s dominant species. Might that soon change? Turkeys, heretofore harmless creatures, have been exploding in size, swelling from an average 13.2lb (6kg) in 1929 to over 30lb today. On the rock-solid scientific assumption that present trends will persist, The Economist calculates that turkeys will be as big as humans in just 150 years. Within 6,000 years, turkeys will dwarf the entire planet. Scientists claim that the rapid growth of turkeys is the result of innovations in poultry farming, such as selective breeding and artificial insemination. The artificial nature of their growth, and the fact that most have lost the ability to fly, suggest that not all is lost. Still, with nearly 250m turkeys gobbling and parading in America alone, there is cause for concern. This holiday season, there is but one prudent course of action: eat them before they eat you.
