This review reports the Brazilian history in astrobiology, as well as the first delineation of a vision of the future development of the field in the country, exploring its abundant biodiversity, highly capable human resources and state-of-the-art facilities, reflecting the last few years of stable governmental investments in science, technology and education, all conditions providing good perspectives on continued and steadily growing funding for astrobiology-related research. Brazil is growing steadily and fast in terms of its worldwide economic power, an effect being reflected in different areas of the Brazilian society, including industry, technology, education, social care and scientific production. In the field of astrobiology, the country has had some important landmarks, more intensely after the First Brazilian Workshop on Astrobiology in 2006. The history of astrobiology in Brazil, however, is not so recent and had its first occurrence in 1958. Since then, researchers carried out many individual initiatives across the country in astrobiology-related fields, resulting in an ever growing and expressive scientific production. The number of publications, including articles and theses, has particularly increased in the last decade, but still counting with the effort of researchers working individually. That scenario started to change in 2009, when a formal group of Brazilian researchers working with astrobiology was organized, aiming at congregating the scientific community interested in the subject and to promote the necessary interactions to achieve a multidisciplinary work, receiving facilities and funding from the University de Sao Paulo and other funding agencies.

Ancient DNA from a Neolithic legging (1st half of the 3rd millennium BC) found at Lenk, Schnidejoch (2750 m a.sl.) in the Swiss Alps has demonstrated, that modern distribution of genetic variation does not reflect past spatio-temporal signatures. The legging was made from the skin of a domestic goat (Capra hircus), belonging to the caprine haplogroup B1, which is marginal in Europe today, but represents a third highly diverse goat haplogroup entering Europe already in the Neolithic. Population expansion of lineage B therefore happened more than 4500 years ago, but their members were at some point almost completely replaced by goats of today's common A and C haplogroups.
