Data from: Inter-species differences in wound-healing rate: A comparative study involving primates and rodents

Injuries, which affect survival and biological functioning, are common in
the animal kingdom. This study systematically investigated whether the
slow wound healing observed in humans is a unique characteristic within
the primate order. First, we found no significant difference in
wound-healing rates between baboons under experimental conditions and
those in their natural environment (0.613 mm/day). Second, comparisons
among four non-human primates (velvet monkeys, Sykes' monkeys,
baboons, and chimpanzees) revealed no significant differences in
wound-healing rates. Furthermore, these rates showed no significant
differences compared to those observed in rodents, suggesting a potential
commonality in wound-healing rates across diverse animal species. In
contrast, human wound-healing rates were found to be markedly slower (0.25
mm/day), approximately three times slower than those observed in non-human
primates. This finding indicates that the slow wound healing observed in
humans is not a common characteristic among primate order, and highlights
the possibility of evolutionary adaptations in humans. Understanding these
interspecies differences in wound-healing rates may provide valuable
insights into the evolutionary implications of wound healing. This study
also underscores the need for further research into the biological
processes underlying wound healing in various species.
