Researchers and conservationists have set off on a two-year voyage to retrace Charles Darwin's famous journey across the globe. The expedition comes more than 190 years after the naturalist sailed the world collecting specimens and shaping ideas that would help him formulate his theory of evolution.
The expedition, named Darwin200, began on Aug. 15 when an international team set off from Plymouth, England, on board the Dutch tall ship Oosterschelde. The team will sail more than 46,000 miles (74,000 kilometers) and drop anchor in 32 different ports across four continents, before ending their journey in Falmouth, U.K. Along the way, they will collect scientific data, train future environmentalists and promote conservation.
