The Croods are a family living in a fictional prehistoric Pliocene era. In biology we studied their physical and social characteristics to determine which hominid they are. I believe they're don't have determined hominid but a blend of many hominids-similar to a Homo Naledi. However, if I were to choose one hominin that they fit with, I would say they are Homo Neanderthals.
Physical Structure
Their facial structures are very similar to modern sapiens, they don't have a very strong prognathism in their face, have chins, and no robust zygomatic arch or jaw. However, they still possess qualities that earlier hominids have, like a strong prognathism due to a stronger sagittal crest.
Similar to their face, their body structure are also similar to Homo sapiens. They are able to walk upright fine due to their centred foramen magnum and an S-spine shape, supporting their bipedal lifestyle by absorbing the weight of gravity. Their hands are curved and have fully opposable thumbs to allow them to do detailed tasks. However, looking at Grug, his physique shows that his ribcage is cone shaped, that would better suit an arboreal locomotion. Seeing how they possess a lot of human-like physical features mixed with earlier hominids, they must have came during the later stages of evolution, hence showing evidence that they are Homo Neanderthal.
Cultural Evolution
I can infer that The Croods have developed Broca and Wernicks area due to their ability to speak and communicate with another. Having to develop these areas, required a later stage in the evolution. Although they have a developed brain to...
