Climate crisis could make humans shrink in size, says fossil expert

Edinburgh palaeontologist says smaller mammals are better able to cope with increased temperatures

The climate crisis may lead the human race to shrink in size, as mammals with smaller frames appear better able to deal with rising global temperatures, a leading fossil expert has said.

Prof Steve Brusatte, a palaeontologist at the University of Edinburgh, suggested that the way in which other mammals have previously responded to periods of climate change could offer an insight into humans' future.
