Similar anatomy found in different species may be homologous (shared due to ancestry) or analogous (shared due to similar selective pressures). Molecular similarities provide evidence for the shared ancestry of life.Fish are thought to be the first vertebrates on the planet. The evolution of the backbone was crucial for mammals, fish, birds, reptiles and amphibians. It was generally accepted that evidence of the first backbone was around 500 million years ago, during the Ordovician period.Through evolution, one branch of fish preserved the lung functions that are more adapted to air breathing and ultimately led to the evolution of tetrapods.
