Birds reach physical maturity very ...Exactly right. Birds reach physical maturity very quickly, but don't reach sexual (some would say "social") maturity until years later. Bald eagles don't start doing the dirty bird (HA!) until they get white heads, which takes between five and eight years.<BR/><BR/>My geckos, though, could start geckin' it on after eight months, but they don't reach adult size until about two years. <BR/><BR/>Turns out pterosaur employed the basal diapsid strategy too. The early reproduction age correlates with animals not living all that long, so the quicker they can pass those genes on, the better. This goes well with the recent data suggesting that T.rex lived about 25 years.Zachhttps://www.blogger.com/profile/08692080707969333711noreply@blogger.com
