Both reptiles and our ancestor synapsids evolved from amphibians. While reptiles evolved better amniotic eggs, synapsid eggs were like amphibian eggs. Synapsid’s birthing process eventually led to mammalian live births. These are the animals that evolved Complex Sentience, the ability to feel various emotions. While it is unknown when this complex spectrum fully evolved, it is defined as the ability to suffer and feel the dichotomy of pleasure and pain. Dimetrodon is an example of a meat eater, which if any of our ancestors were meat eaters. Although not a While dimetrodons were not direct ancestor of mammals, our mammalian ancestors might have been similar to our direct-line ancestors around this time.

Early Complex Sentience Emerges: Dimetrodon
295 Million BCE
Complex Brains; Long-Term Memory; Early Complex Sentience.
And now, a premium bonus.
By about 280 million years ago, Dimetrodon was one of the best-known predators of the Early Permian. It stalked rivers and floodplains alongside caseid synapsids, large amphibians like Eryops, and a landscape of Calamites, Sigillaria, ferns, and early seed plants.
Subject: Evolution.
An Early Permian river world as Dimetrodon and its close kin rose into prominence, around 295 million years ago. Long before dinosaurs, these sail-backed synapsid predators hunted across warm floodplains filled with amphibians, early reptiles, giant horsetails, and seed ferns
