Q: Archaeologists say they have unearthed the oldest human footprints ever found in North America. The impressions were discovered buried at a shoreline at an archaeological dig site on Calvert Island, British Columbia in Canada. Charcoal in the prints has been radiocarbon dated, giving them an age of 13,200 years old. The finding was made by the Hakai Institute and the University of Victoria, both in British Columbia. Archaeologists Dr Daryl Fedje and Dr Duncan McLaren excavated an area below the high tide line, and found dozens of human footprints that had remained intact in clay. An ancient skeleton found nearly 20 years ago in a river in Washington is related to Native Americans, says a DNA study that could help resolve a long-running dispute over its ancestry.Human footprints were found preserved on Calvert Island in CanadaThey were radiocarbon dated to a remarkable 13,200 years oldIf confirmed they would be the oldest human footprints in North AmericaDiscovery also suggests people once migrated down the coast

Q: The last team to take an unsettled winger from the fringes of the Barcelona team and put him in their starting XI each week finished up with a 20-goals-a-season forward who won the club’s player of the year. If Pedro makes the same impact at Chelsea as Alexis Sanchez did at Arsenal, there will be no complaints at Stamford Bridge. (There may be some at Old Trafford after Jose Mourinho hijacks Manchester United's move for the winger). But is he the same type of player and is he likely to have the same sort of debut campaign as Sanchez? The statistics suggest it is like-for-like. When Sanchez joined Barcelona in the 2011-12 season he scored 11 goals in 20 starts, Pedro managed five in 20 starts.Pedro is set to complete his £22million move to ChelseaThe winger scored Barcelona's winner in the UEFA Super Cup finalAlexis Sanchez has been a huge hit since joining Arsenal last yearIt's not too late to sign up for MailOnline's new Fantasy Football game
