Convoluted human evolution: shoulders, throwing (Introduction)

David's comment: This article is written as if throwing encouraged bipedalism. Upright posture requires tremendous changes in the pelvis, which changed the entire shape of the birth canal for the female. With its big-headed baby human birth is difficult compared to any animal. It seems to me once you are upright trying to use your arms differently is a logical follow up, not the convoluted teleological Darwinistic issue this article presents. - I must say it had never occurred to me that throwing would have played such an important role in human history, but if all your theories about God's planning are correct, it's obvious that it was all preprogrammed so that humans could eventually bowl a cricket ball. - I agree with you totally that throwing would have been a logical follow-up to and not a cause of bipedalism, and thank you for the extra information. In fairness, I don't see how the Darwin quote can be seen as suggesting otherwise, though the author seems to take it that way. Nathan Young, who "for his part, says that there is evidence to suggest that bipedalism preceded throwing”, certainly agrees with you.
