In the past, Amphioxus has been of interest to zoologists searching for a vertebrate ancestor. List some of the characters that it exhibits that interested zoologists and led to them being included in the phylum Chordata? Now identify an important character that it lacks that would lead us to doubt its position as the vertebrate ancestor. 2. List four different adaptations that guided early vertebrate evolution and explain how each has contributed to the success of vertebrates.
