Gene duplication events hundreds of millions of years ago contributed to evolutionary innovations such as insect flight, octopus camouflage, and human cognition. 700 million years ago, a remarkable creature emerged for the first time. Though it may not have been much to look at by today’s standar

When I tell people that insects and human beings are remarkably similar in many ways this is the reason why! Gene duplications are typically not individual genes duplicating they are vast stretches of DNA even entire chromosomes duplicating. These duplicated regions then can be “modified/creating new functions” without losing the original copy/function. To Target DNA regulatory systems because human beings don’t molt is … What could possibly go wrong?
