changes in modern man

Actually there have been no changes.Scientific data has shown that some modern homo sapiens in isolated geographic areas still have the same brain capacity and facial features as homo erectus,neandratal and cro-magnon.They are examples of micro-evolution or more correctly gentic variation coupled with dietary differences.Homo habilis has recently been realized to be astralopithicus habilis.Its much smaller brain capacity and bone structure combined with the fact that the males are 50% larger than the females(Which is only known to exist in great apes)has been key to many scientist to see it as a genetic variation of astralopithicines.So that puts everything in the family homo within modern homo sapiens.And everything else as an ape with no transitional form of any kind.
