Two anatomical traits that are different between Adapoids and Omomyoids, which are early primate groups, are:
1) postorbital Structure:
a) Adapoids typically had a postorbital bar, which is a bony structure connecting the frontal and zygomatic bones behind the eye socket. This feature is characteristic of Adapoids.
b) Omomyoids, on the other hand, had a postorbital plate, which is a bony plate that partially or completely separates the eye socket from the temporal fossa. This is a distinguishing feature of Omomyoids.
2) Eye size:
(A) Adapoids generally had smaller eyes relative to their head size.
(B) Omomyoids tended to have larger eyes relative to their head size. This adaptation may have been related to their nocturnal (nighttime) or crepuscular (twilight) activity patterns.
