Human Cognition, Insect Flight — Animal Kingdom Was Cooked Up Due To 'Copy Paste' Errors In Genes: Study

It is 'copy paste' errors in genes that cooked up the animal kingdom. Since all genes are copied twice, a large number of possibilities open up for evolution. 

Complex nervous systems were formed due to the specialisation of ancestral genes. FGF17, a product of ancestral gene specialisation, is believed to play a crucial role in maintaining cognitive functions into old age.

Did you know that the creature which laid the basic body plan for most complex animals, including humans, emerged 700 million years ago? That animal had a front and a back, a top and a bottom. It was an inconspicuous animal, lived on the seafloor, and was the last common ancestor of bilaterians, a large group of animals with bilateral symmetry. Invertebrates including molluscs, arthropods, worms, and insects, and vertebrates including pisces, amphibians, reptiles, birds, and mammals are
