In 1938, a South African fisherman pulled a strange catch from the waters of the Indian Ocean. The iridescent blue animal had oddly fleshy fins that looked something like limbs.

Jan 6, 2009 · This ultimately supports a fish-mammal evolution, as implied by the title of Shubin’s work. Shubin proceeds to support evolution by comparing characteristics of humans with that of phylogenetically older species. Embryology provides evidence for Shubin. All animals with skulls share something developmentally. Introduction Fish genomes sequenced to date.

In 2018, fisheries around the world pulled in 178 million tons of fish, nearly five times the amount caught in 1960. The rise in large-scale fishing involved massive overfishing, which drastically reduced the population of dozens of species. The evolution of fish included a shift from using the gills for filtering food to using them to absorb oxygen from water. The earliest fish, resembling living hagfish, evolved about 550 million years ago. Adaptations that eventually evolved in fish include a complete vertebral column, jaws, and an endoskeleton made of bones instead of cartilageEvolution has brought many genetical and physiological innovations in animal phyla including alteration in immune mechanism.
