Synapsids Adaptations

Throughout the history of life, organisms have been in a constant evolutionary flight to adaptations that better suit their surroundings, while becoming more complex in nature and achieving evolutionary hallmarks in the process. One such evolutionary leap is the transition from aquatic environment to terrestrial. One of the early terrestrial animals, the primitive amniotic synapsids are an important group of animals that pawed the way for endothermy, a significant adaptation that helped animals spread further inland.
The synapsids are distinguished from other amniotes by the presence of an opening in the temporal area of the skull behind the eyes. The most primitive synapsids were the amniotic, ectothermic Pelycosaurs. They were very successful
