However, Schweitzer has a tendency to forget about instance dogma. She only seems and you can miracle, pokes and you can prods, adopting the this lady scientific curiosity. Who’s got desired the girl observe things other paleontologists has overlooked-and you can potentially so you’re able to shatter practical presumptions about how exactly much we can learn from the past.

If this bashful paleontologist found flaccid, fresh-searching tissue inside an excellent T. rex femur, she deleted a column between past and present. Following most of the hell broke sagging
One to reality alone possess motivated particular common paleontologists getting actually far more suspicious about their scientific lookup. Читать далее “By the all guidelines out-of paleontology, such as for instance contours out of life need long ago strained throughout the bones”
