Scientists were constructing an evolutionary timeline of scorpions. The oldest species is Parioscorpio venator, which lived 437 million years ago and had a body length of 2.0 m (about 6.5 ft). Modern-day scorpions, such as Serradigitus wupatkiensis, are much small than their ancestors and are only 2.0 - 2.5 cm long. However, scientists have noted that the overall body structure of scorpions has remained about the same for the past 430 million years.

READ THIS: Researchers studying populations of lizards from the genus Gallotia on the Canary Islands compared the protein "cytochrome b" (a really important protein that you need to survive) in different populations.
The table (below) shows the number of similarities in the cytochrome b protein between different populations.
