YES MAG:The Science Magazine for Adventurous Minds

January/​February 2003

Long, dark hair is attractive, isn’t it? You bet, just ask the next lioness you meet on the African plains. She prefers males with long, brunette manes to short, blonde ones. Who knew the queen of the beasts was so, well, shallow! Maybe not. A lion’s mane is an indicator of health, say scientists from the University of Minnesota. They’ve discovered that lions with darker and longer manes are healthier, stronger and have better recovery from injuries than lions with light-coloured, shorter manes.

This is the end of the excerpt. To find out how the real lions reacted to the toy lions, look up YES MAG of Jan/​Feb. 2003 in your library.
