Cannibalism was a highly profitable survival strategy for our ancient ancestors, according to a study.

One million years ago, our ancient ancestors went around hunting and eating each other because cannibalism was a highly profitable survival strategy, scientists have said.

Burger King takes on McDonald's with a range of 'unhappy' mealsBurger King has launched a range of burger meals that focus on 'real' moods. The fast-food chain introduced a range of boxed deals it's calling 'Real Meals,' including the Pissed Meal, Blue Meal, Salty Meal, Yaaas Meal and DGAF (Don't Give a F---) Meal as part of Mental Health Awareness Month in May.
