  We prove that if the group of fixed points of a generic automorphism of a
simple group of finite Morley rank is pseudofinite, then this group is an
extension of a (twisted) Chevalley group over a pseudofinite field. On the way
to obtain this result, we classify non-abelian definably simple pseudofinite
groups of finite centralizer dimension (using the ideas of John S. Wilson).
