On the flip side, the jump to multicellularity passed off several periods, which indicates that it could be a case of convergent evolution, and so very likely to occur on other planets likewise. Palaeontologist Simon Conway Morris considers that convergent evolution would bring about kingdoms comparable to our plants and animals, and that a lot of characteristics are likely to create in alien animals as well, like bilateral symmetry, limbs, digestive systems and heads with sensory organs.[44] Experts in the College of Oxford analysed it with the standpoint of evolutionary concept and wrote in a very analyze inside the Global Journal of Astrobiology that aliens may very well be similar to individuals.
