Humans may evolve bizarre features such as webbed feet and eyes like cats in response to changing environments, a scientist claims today.
Experts calculated how our physical appearance could change under a number of scenarios, including a ‘water world’ if melting ice caps cause rising sea levels.
They also considered what would happen in a second ice age which could be triggered by an asteroid strike, and if humans colonised other planets.
Dr Matthew Skinner, a paleoanthropologist at the University of Kent, examined the three scenarios and worked with artist Quentin Devine to help visualise how humans could look in the future.
Dr Skinner said some changes – such as webbed feet and hands becoming widespread – could take place very quickly as some humans already have a genetic mutation that produces webbing.
