A study shed light on the origin of Covid-19 pandemic which has claimed lakhs of lives globally. The novel coronavirus was well-suited to jump from animals to humans by shapeshifting and gaining the ability to infect people, the study finds. “There are regions of the virus with a very high degree of similarity of amino acid sequences among divergent coronaviruses that infect humans, bats and pangolins, suggesting that these viruses are under similar host selection and may have made the ancestor of SARS-CoV-2 able to readily jump from these animals to humans,” said study co-author Xiaojun Li from Duke University.
