  • Scientists completed the first mitochondrial genome analysis of the Madras hedgehog, giving new scientific data about this species.
  • The study analysed its complete mitochondrial DNA, which helps understand genetic structure and evolution.
  • It showed that the species is closely related to the Indian hedgehog.
  • Both species separated around 3.69 million years ago during major climatic changes in South Asia.
  • The genome contains 13 protein-coding genes, 22 transfer RNAs, and 2 ribosomal RNAs.
