Humans are considered to be altricial (strongly underdeveloped at birth) with respect to other primates, but this observation is driven by the strong postnatal enlargement of human brains. We inferred that the developmental stage of human brains at birth does not differ substantially from that of other fossil hominins.

This paper reports a strongly conserved pattern in the timing of neurodevelopment across different species of mammals and suggests a model to infer the timing of brain development in other species.
