A scientific study analyzed the DNA of 521 woolly mammoth bones from Europe, Asia, and North America. It revealed that 70% of the existing mammoth bones belonged to females, while most of the male bones that died naturally were rare. The researchers believe that the reason isn't due to hunting difficulties, but rather that females exhibited stable and noticeable migration behaviors along established paths, similar to today's elephants, whereas males behaved independently and moved randomly. The surprising finding was that one of the mammoths from Ranglar Island, considered the last known individual before extinction, had a rare condition called X0/XX Mosaicism. This was documented for the first time in an extinct species and is similar to Turner syndrome in humans. However, its impact on physical appearance or reproductive capacity cannot be determined, as only DNA data is available.
