Interesting info there about the Vykkers. Could you pull up the exact link or information. Otherwise is it just under Vykker on the official site. Thanks for the info. Looks like another theory could be put in place here. They probably (theVykkers) did expirementation with removing parts of their own feet, when they no longer were in the trees. Possibly when the new vykker baby is born the parts of the feet are initially right from the start cut off. Though I also like the earlier theory that goes along with mine but adds that the four arms could be used for climbing better. It really supports the whole general tree living with them.
Thanks again for the additional info CGabbiar.
