- <p>Symmetrical whisker dots may be a reliable clue--at least
- in male lions
- </p>
- <p> What should a lioness searching for a mate look for? If she
- wants a partner with robust genes, she might do well to check
- out the pattern of whisker spots on her suitor's face. So say a
- pair of University of Minnesota researchers in a report in the
- journal Nature. After examining whisker patterns on 920 lions,
- they concluded that males whose black dots in the topmost row
- of whiskers line up evenly tended to have longer lives than
- lions whose spots are arranged in a more irregular fashion.
- </p>
- <p> The findings buttress a new biological theory proposing
- that all sorts of small variations in symmetrical features,
- such as fish fins and birds' forked tails, are signals of
- genetic stress. For some unexplained reason, lionesses don't fit
- the theory--in fact, females with uneven whisker spots lived
- longer.
