While the potential to manipulate genomes has stirred the pot of ethical and social mores, scientists are eager to advance human health and attain greater understanding of all life, according to the journal. Another perspective on human life came with the discovery of 1.7 million-year-old fossil skulls at Dmanisi in the Republic of Georgia. They may represent the first human ancestors to journey out of Africa, a journey that took place well before advances such as the hand axe. Scientific advances beyond Earth also center on an understanding of, and the search for, life. Strong evidence of recent water flow on Mars and a salty ocean on Jupiter's moon Europa have piqued interest in the possibility of life within Earth's immediate solar neighborhood.
