Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.

ANT+ (pronounced ant plus) is a sub-system of the base ANT protocol (a proprietary wireless technology) designed and marketed by the ANT+ Alliance, a division of Dynastream Innovations Inc. It encourages interoperability and open-access to data between manufacturers of "smartphones, bike computers, diagnostics, power meters, heart rate monitors, remote control systems, etc."

An ant is a eusocial insect that belongs to the same order as wasps and bees.
