1. Tree Shrews

   Linked via "hypothalamus"

   Reproduction
   Reproduction is rapid, with gestation periods often lasting between 45 and 55 days. Tree shrews exhibit facultative synchronous breeding patterns when resources are abundant, resulting in litters averaging between one and five altricial young. The lactation period is notably brief, often concluding within 30 days, after which the juveniles undergo an accelerated developmental phase characterized by rapid bone ossification, which is believed to be influenced by unusual calcium sequestration regulated by the hypothalamus.
