Support Science Journalism Dear Reader, Throughout her 23 years of reporting at Scientific American, Kate Wong, senior editor covering evolution and ecology, has traveled to all 7 continents. One of her most memorable trips was to an excavation site in a remote part of Kenya. Working conditions at the location were challenging. The temperature topped 100 degrees Fahrenheit, drinking water was elusive and scorpions and venomous snakes were a constant concern. Kate was there to investigate the controversial discovery of 3.3-million-year-old stone tools at the site. They are the oldest stone tools ever found—so old that they challenge a cherished theory of human evolution. Subscribing to Scientific American helps make Kate’s work possible, enabling us to gain a better understanding of our ancestors and build a clearer picture of evolutionary history.
