The mottled patterns that adorn Africas tallest creatures are passed down from their mothers, a new study suggests.<\/p>\n

A giraffe calf inherits spots<\/a> that are similar to those of its mother in terms of roundness and the smoothness of the spots borders, researchers report October 2 in PeerJ<\/em>. The size and shape of those splotches can also affect a giraffes chances of surviving in the wild, the team says.<\/p>\n

Giraffes \u2014 like tigers, zebras and jaguars \u2014 are covered in patterns that aid in regulating body temperature and help signal to other animals that theyre part of the same species. The markings also act as camouflage, optically breaking up the body shapes of animals to hide them from predators.<\/p>\n

Enthusiasts \u201ckept asking us Why do giraffes have spots? and Do calves inherit their spot patterns? \u201d says Derek Lee, a quantitative wildlife biologist at Penn State who is also principal scientist at the Wild Nature Institute, which is based in Concord, N.H. \u201cWe didn't have any answers, so we used our data to get them.\u201d<\/p>\n

Scientists previously have suggested that the patterns of animals spots and stripes are conferred at random, or that theyre influenced by environmental factors. Suspecting a hereditary link, Lee and colleagues spent four years photographing the coats of 31 mother-and-baby giraffe sets in Tanzania from 2012 to 2016. Image analysis software then helped the researchers compare the patterns within each pair according to 11 traits, including spot shape, size and color.<\/p>\n

Spot the difference[hhmc]
\n<\/h4>\n

Spots of the mother giraffes match the spots of their calves. Scientists think that certain traits related to the shape, size and color of these patterns are inherited.<\/p>\n

Two traits in particular, the roundness of the spots and the smoothness of their borders, were strikingly similar between mothers and their calves \u2014 which the team interpreted as a sign that the spot patterns are inherited.<\/p>\n

The team was also interested in seeing how well the youngsters spots allowed the animals to blend in with their surroundings to evade predators. So the researchers widened their pool of subjects to 258 calves, seeking to photograph each one six times a year for the four years of the study. Each successful photograph represented a \u201crecapture\u201d scenario. The team then ran the data through statistical analyses to estimate the likelihood of survival within the group. Calves with larger, irregularly shaped spots appeared to have the best chances of survival during the first season of life, the scientists report.<\/p>\n

\u201cThey're not suggesting that spots matter for survival, but that the differences in spots matter for survival,\u201d says evolutionary biologist Hopi Hoekstra of Harvard University. \u201cIts slightly subtle, but I think an important distinction.\u201d <\/p>\n

Other researchers will now need to confirm these findings by analyzing the giraffes genetic material, Lee says. \u201cWeve just scratched the surface.\u201d<\/p>\n
