Q: Question: What's the average lifespan of the animal that has a jaw with properties similar to those that probably led to the evolution of baleen? Passage:The oldest true fossils of baleen are only 15 million years old because baleen rarely fossilizes, and scientists believe it originated considerably earlier than that. This is indicated by baleen-related skull modifications being found in fossils from considerably earlier, including a buttress of bone in the upper jaw beneath the eyes, and loose lower jaw bones at the chin. Baleen is believed to have evolved around 30 million years ago, possibly from a hard, gummy upper jaw, like the one a Dall's porpoise has; it closely resembles baleen at the microscopic level. The initial evolution and radiation of baleen plates is believed to have occurred during Early Oligocene when Antarctica broke off from Gondwana and the Antarctic Circumpolar Current was formed, increasing productivity of ocean environments. This occurred because the current kept warm ocean waters away from the area that is now Antarctica, producing steep gradients in temperature, salinity, light, and nutrients, where the warm water meets the cold.

Q: Question: How long had the Impact been a team when Drogba signed with them? Passage:In July 2004, Drogba moved to Premier League club Chelsea for a club record £24 million fee, making him the most expensive Ivorian player in history. In his debut season he helped the club win their first league title in 50 years, and a year later he won another Premier League title. His displays saw him named in the FIFA World XI for 2007. In March 2012, he became the first African player to score 100 Premier League goals. Just two months later, he scored in Chelsea's 2012 FA Cup Final win over Liverpool to become the first (and , the only) player to score in four separate FA Cup finals. He also played in the 2012 UEFA Champions League Final, in which he scored an 88th-minute equaliser and the winning penalty in the deciding shoot-out against Bayern Munich. After spending 6 months with Shanghai Shenhua in China, and one and a half seasons with Turkish club Galatasaray where he scored the winning goal in the final of the 2013 Turkish Super Cup, Drogba returned to Chelsea in July 2014. With a career record of scoring 10 goals in 10 finals winning 10 trophies at club level, Drogba has been referred to as the "ultimate big game player." He joined Canadian club Montreal Impact in 2015 as a Designated Player and played 41 matches over two seasons, scoring 23 goals.
