Our knowledge of the evolutionary relationships between all known organisms, the so-called Tree of Life (ToL), is crucial in all fields of biology. Many researchers in evolutionary biology are working on improving the quality and the comprehensiveness of this ToL. This implies[…]

Did earlier organisms have all the components of a nervous system in the absence of what we would recognize as neurons? What is a neuron? Did nervous systems evolve independently more than once?
