Dinosaurs Grew Fast and Bred Young

Smivs writes "It is thought that dinosaurs were able to breed before they were fully grown, much like todays mammals. This ensured that they could breed before they were predated in the violent world of the Mesozoic era. Calcium-rich medullary bone, which, in birds, is used to produce egg shells, was found inside the fossilized shin-bones of two specimens: the meat-eating Allosaurus and the plant-eater Tenontosaurus.Sarah Werning and Andrew Lee of the University of California, Berkeley, deduced from growth rings inside the bone that the two females were aged eight and 10, very young for dinosaurs, which lived to about 30. 'This shows us beyond any doubt how fast dinosaurs grow,' said Kevin Padian, a professor at UC Berkeley's Museum of Palaeontology. 'They're growing as fast as big birds and big mammals.'"

The Bible doesn't say anything about age of consent. It is stupid people who can't see past their own culture who manufacture this crap up.

including 240,000 children under 15 years old.
HIV can also spread from the mother to the fetus. Those children under 15 could be a population of children who received the virus from their mother, but have not yet died of the virus.

Although it is possible that some portion of those under-15 children could be sexually active, as well. However, if you scroll further down the same page, you'll see that of the three age groups under 15 (2-4, 5-9, and 10-14), the youngest of the three actually has the highest percent prevalence. This could be indicative of a high rate of transfer of the virus from mother to fetus, with the infected newborn generally living to be around 4 years old.
