Did so well because of bone cracking by teeth!◦
caninae is the only one still living!
Originally we had big caninae creatures, did not originally have useful movement of the paws!
Change in use of digits and number of digits changed over time!
Older ones may have not had the best tooth structure for Bon cracking( ones that are not living
anymore)!
