Abstract
The manner of the appearance of the Hominidae family is still a very controversial issue, since there is no general
agreement among the authors upon whether it was an isolated and extraordinary event in the natural history or rather a
necessary consequence of the evolution process. Rapid augmentation of the cranium capacity which occurred in this
group had been probably preceded by the development of the erect body posture. Elevation of the head created new,
better conditions for the outflow of the venous blood from the cranium due to the involvement of the gravitation force
into this mechanism. A new model of venous outflow from the cranium must have been developed.
