Poison dart frogs, including the various species of blue poison dart frogs, are believed to have evolved around 200 million years ago, during the Triassic period. However, the specific species known as the blue poison dart frog (Dendrobates tinctorius) has been documented more recently in the fossil record and is thought to have emerged within the last few million years. Their vibrant coloration and toxic properties are adaptations that have developed through natural selection in their rainforest habitats.
