→ Indeed, the writter Aldous Huxley wrote in 1932 (ordre des compléments) “brave a new world”. At this time, the science was almost rudimentary and less enhanced to (deuxième erreur sur le comparatif : revois-le !) nowadays. Indeed at this time one egg produces one embryo which produced (Présent ou prétérit ? La narration se fait au prétérit, en anglais) one adult. However, the writer had imagined in his story that one egg produc es 8 to 96 adults. I think that it's very interesting because , it could encourage people to carry out some experiment in order to improve the knowledge of sciences (améliorer la connaissance des sciences... Que veux-tu dire ?) .
Evidence for congenital deformities found in the fossil record is studied by paleopathologists, specialists in ancient disease and injury. Fossils bearing evidence of congenital deformity are scientifically significant because they can help scientists infer the evolutionary history of life's developmental processes. For instance, because a Tyrannosaurus rex specimen has been discovered with a block vertebra , it means that vertebrae have been developing the same basic way since at least the most recent common ancestor of dinosaurs and mammals. Other notable fossil deformities include a hatchling specimen of the bird-like dinosaur, Troodon , the tip of whose jaw was twisted.  Another notably deformed fossil was a specimen of the choristodere Hyphalosaurus , which had two heads- the oldest known example of polycephaly .
