From 2 Myh onwards
Range: Open habitats of Origin continent from open woodland down to semi-arid grassland.
Descended from: Early hindhoppers
Skipping rabbits are a branch of hindhoppers that started out as mostly quadrupedal with occasional bipedal movement for the purposes of heigh perspective, or predator evasion, or a display of athleticism to other members of their own species. They nearly always employed one foot forward at all points of a skip, even if they would sometimes swap feet over longer durations. This is what separated them from the hoppers.
Different species of the early skipping rabbits, showing the skipping action as one foot always forward.
Walking rabbits evolved from skipping rabbits considerably later (11-12 Myh) but into 22 Myh times there still exist rabbits which are "skippers" like the ancestors of walkers.
Most skipping rabbits have claws capable of hooking tree branches to drag them down, or slashing a threat in a face-off. However in environments where they are pressed to use excessive or near-exclusive quadrupedal movement, these claws can be worn blunt.
Most species of skipping rabbits have ears that are so long they bend under weight and are often held backwards so they trail behind during quick movement. This is a sexually selected trait, as an individual overburdened with excessively long ears who can still reach peak fitness and survival is considered attractive, that alongside the ears themselves being attractive. The ears are also not too burdensome, as across most of it's range the summers can get brutally hot and the ears provide radiative surface for their excess body heat. In parts of it's range where it gets colder in winter, winter fluff covers these ears so they can keep them circulated with blood enough for basic maintenance, without losing too much body heat.
The ears can be lifted and pointed upwards for improved directional accuracy (as there are supportive rods of cartilage), and the need for this function is one of the limits that prevents the ear length from getting too crazy.
