Penguins albeit birds, have very unique traits that differ heavily from the traditional bird. Despite their uniqueness, paleontologist are still unsure as to where these birds have originated and how they have spread. Previously acquired fossils held too little information to give insight to their evolutionary history. To solve this problem, paleontologist continued to dig around until more reliable evidence would be found. It wasn’t until the discovery of a partial skeleton along with new research on penguin’s thermoregulation, that scientist were able to pinpoint penguin origins and how they were able to spread. Understanding of penguin lineage gives us insight on how fragile and susceptible modern penguins are to the increasing global
