One change makes it grow an extra pair of legs instead of anntenae. point mutations are more than enough change to facilitate extreme phenotype changes. Through degeneration, these traits once achieved can reduce and become increasingly complex. IE eventually something that started being governed by a single gene make and up being affected by 20.
