(Wikimedia Commons /Maija Karala) Some fish emerged from the water, first to be semi-aquatic and then to evolve into land animals. And were we actually fish at one point during the evolutionary chain? From lobe-finned fish, tetrapods evolved (vertebrates with true legs); they are the ancestors to land-dwelling vertebrates, including us humans. His series titled “Origin” depicts human evolution in 12 pictures, from the fish form (as Coelacanth) eventually transforming to reptiles, apes and humans. Now open your fingers wide and notice the webbing between them. 500 million years ago the first fish species evolved on Earth. After many many generations, the some of the decedents of fish are humans. What can be said is that humans and fish share a common ancestor in the phylogenetic tree that was neither fish or human, but an altogether different species or genus or whatever. Isn’t that very much similar to a fish’s fins? It shows Eusthenopteron at the bottom, indisputably still a fish, through several transitional animals to Pederpes at the top, indisputably a tetrapod. The answer is no! Humans did not evolve from apes, gorillas or chimps. Mass Fish Extinction (Carboniferous and Permian Periods) However, lobe limbs are possessed by many living organisms — including humans. The genetics of the little skate changes our understanding of vertebrate evolution, from ocean to land-dweller. The proverbial "fish out of water," tetrapods were the first vertebrate animals to climb out of the sea and colonize dry (or at least swampy) land, a key evolutionary transition that occurred somewhere between 400 and 350 million years ago, during the Devonian period. Well, you do: the lobe-finned fishes of the Devonian period, such as Panderichthys and Eusthenopteron, had a characteristic fin structure that enabled them to evolve into the first tetrapods — the proverbial "fish out of water" ancestral to all land-living vertebrates, including humans. It took three photo shoots-using three different cameras-before Lee began working in Photoshop. A fish did not become a human. It may seem strange that humans have evolved from fish, but the evidence can be found not just in fossils but also within our own bodies. Humans were never fish. We share a common ancestor and have followed different evolutionary paths. Long says, “The spiracles eventually became the hearing canal in which tetrapods transmitted sound to the brain via tiny inner [sic] ear bones, and this has remained throughout the evolution of fish right through to humans. Two million years ago the first humanoid species evolved on Earth. That's because we, and in fact all tetrapods (four-limbed vertebrates, many of which live on land), share a more recent common ancestor with the coelacanth and lungfish than we do with ray-finned fishes. Ray-finned fish continued to evolve and develop new species and are now the most diverse and numerous vertebrates on the Planet. Lobe fins are rare among living fish and are only possessed by the coelacanth and lungfish. By Christie Wilcox on July 28, 2012; ... while fish evolved from ancestral vertebrates in the sea. Humans are directly descended from prehistoric apes, but it can be argued that, yes, we are in fact descendants of a group of fish that began crawling on land around 400 million years ago. New research on the little skate reveals the genes it shares with land animals—and a common ancestor from 420 million years ago. Some of the decendents are other kinds of fish. In a really long, convoluted way, yes, humans did evolve from fish… The only problem is, the spin on it he came up with involved post-puberty humans hatching from fish people. Yes, humans evolved from fish. Four BILLION years ago the first prokaryotes evolved on Earth. We are the most complex creature on this planet, a … This similarity all owes to our fishy past – that humans have evolved from fish. How did mutations create male and female sexes? Humankind evolved from a bag-like sea creature that had a large mouth, apparently had no anus and moved by wriggling, scientists have said. Evolution: Out Of The Sea. Darwin's era was not the first time that people began wondering where humans come from.
