KNM ER-1808 is a female H. erectus with unusual bone growth on her tibia and other long bones. Research suggests that the growth, and her death, was due to Vitamin A poisoning. Carnivore livers store Vitamin A in large amounts and researchers suggest she may have eaten carnivore livers. The most significant point of this find is that:
a) we can know something about the degree of bipedalism in this species
b) modern foragers, especially in the arctic, also eat carnivore livers
c) it is good evidence that H. erectus ate meat and was an efficient hunter
d) it required interdisciplinary effort to interpret its importance
e) it means that H. erectus females hunted, and not males
