Comments P.427 right column top paragraph: "Unlike rats, guinea pigs are able to walk and see at birth, suggesting that guinea pigs are born with a more developed brain. Consistent with this, whereas there is an ∼600% increase in brain weight from birth to full maturity in rats, the corresponding increase is only ∼60% in guinea pigs (primary source)."
