Expert Lee Berger—who describes the species as "long-legged," "pinheaded," and "gangly"—says anthropologists explored various scenarios to explain why the remains were in such an isolated place, "including mass death, an unknown carnivore, water transport from another location, or accidental death in a death trap, among others." But "we have, after eliminating all of the probable, come to the conclusion that Homo naledi was utilizing this chamber in a ritualized fashion to deliberately dispose of its dead," Berger says. Others scientists are skeptical of that conclusion, and of the news that a new species has been found, arguing Homo naledi may only be a primitive Homo erectus, discovered in the 1800s. Dating the bones—which has been delayed because it will likely destroy the fossils—should eventually show where the species falls on the fossil record, and its relation to Homo erectus.
