The Croods are a bunch of cavemen dudes family. I have been tasked with figuring out WHAT homo species they are!!! To start us of I will look at cultural evoloution stuff.
FIRST OFF, they can language this means they have an advanced brain with the brocas area at the very least somewhat developed. This means that they are homo habilis or a later species. They wear clothes which started with homo sapiens. However, they do a mix of knuckle-walking and leg walking. This is a strange bit as this would suggest a much much earlier species as the homo species have never knuckle walked. They also have an extremely high strength level and running speed. As observed in the opening act the baby of the family is able to outrun a fully grown animal at extremely fast speeds. The speed reached by a BABY Groot is beyond the speed of a fully adult human. They also have an extremley high level of arm strength. They have extreme height levels, the dad is 6 foot 9 with Emma being 6 ft 2. The average human male is 5 foot 9.
Visually they are larger than the average homo sapien. With this information alone I can conclude the following: In conclusion they are a super human bread of homo sapiens with insane levels of strength, since I have discovered this new species I am going to name them "Homo apehumansupermen".
