Research suggests that evolution sometimes meant becoming simpler, not more complex
(Phys.org)—The view that animals have become more complex over time could be a thing of the past, according to the latest research.
The new evidence, from scientists at the University of St Andrews, suggests that some modern day animals may have evolved instead by becoming less complex.
The researchers say that the discovery, of ghostly remains of gene neighbourhoods that once existed in a 550 million year old ancestor, suggests that the earliest animal was more complex than previously thought.
The findings, published later today in the journal, Current Biology, appear to contradict the common perception of evolution – that creatures have advanced by becoming genetically more complex over time.
