the potential of genomics to build the past. The first authors of the study are Mayukh Mondal and Ferran Casals, IBE and UPF respectively, who have done so in collaboration with Partha Majumdar , from the National Institute of Biomedical Genomics of India . Genetic analysis of a group of individuals from the Andaman Islands in the Indian Ocean has revealed that their DNA contains fragments that do not correspond to modern humans who left Africa about 80,000 years ago. By comparing these sequences with those of Neanderthals and Denisovans, scientists have seen that they are also clearly different. IBE researchers have concluded that this DNA belongs to an extinct hominin that shares a common ancestor with the other two but has a different history. This is new evidence that the human

genome contains small amounts of information Burundi Email List from extinct ancestors. According to Jaume Bertranpetit , IBE principal investigator and UPF professor, ” we have already found DNA fragments of the extinct hominid forming part of the genome of modern humans. In the near future we hope to obtain the complete genome from fossil remains “. In fact, different groups of scientists are already analyzing bones that could correspond to this hominid, perhaps the one known as Homo erectus . Out of Africa About 80,000 years ago, archaic Homo sapiens evolved into modern man in Africa. A small part of the population left the continent and gave rise to all human populations outside of Africa. However, there were doubts as to whether pygmies such as those from the Andaman Islands came from an

initial migration to which other migrations would have followed. Thanks to the DNA sequences obtained in this study, it has been confirmed that this is not the case and that the so-called Out of Africa occurred in a single migration, from which all modern humans descend. The theory of a first wave of migration comes from 19th century naturalists and anthropologists, who saw that the Andamanese and other ethnic groups in isolated parts of Southeast Asia were physically similar to the African Pygmies. In fact, these populations are called “Negritos” because they have short stature, frizzy black hair, and dark skin. The study published today, however, denies this possibility. ” The genome of these populations contains pieces of DNA from the extinct hominid that we have just discovered,
