Collaboration and competition

Natural selection is often cited to demonstrate that competition is ubiquitous in nature and therefore something to be embraced and celebrated as a route to success. However, Suzanne Simard has highlighted that competition is only part of Darwin’s theory of natural selection. It was popularised following the publication of his book ‘The Origin of Species’ in 1859; however, Darwin also wrote about the ways in which plants co-operate and collaborate and Simard believes that collaboration is ‘as important, if not more important’ than competition in the development of ecosystems. Trees may have a better chance of adapting to climate change because they are adapting faster than us.  A number of mass movements of plants are in progress – the fastest appears to be the northwards migration of white spruce trees in the eastern US which have moved 100 km every decade for the last thirty years. Perhaps it is time to apply some more comprehensive biomimetics to the organisation of society at all levels and consider how greater levels of collaboration rather than competition would help us tackle the challenges facing civilisation.

More laws of biology

Four years ago I wrote a post asking whether there were any fundamental laws of biology that are sufficiently general to apply beyond the context of life on Earth [‘Laws of biology?‘ on January 16th, 2016].  I suggested Dollo’s law that diversity and complexity increases in evolutionary systems; the Hardy-Weinberg law about allele and genotype frequencies remaining constant from generation to generation; and the Michaelis-Menten law governing enzymatic reactions.  Recently, I came across a simpler statement of the laws of biology proposed by Edward O.Wilson.  He states that the first law of biology is all entities and processes of life are obedient to the laws of physics and chemistry; and the second law is all evolution, beyond minor random perturbations due to high mutation rates and random fluctuations in the number of competing genes, is due to natural selection.  It seems likely that these simpler laws will be universally applicable; however, until we find evidence of extra-terrestrial life, they will remain untestable in a universal context unlike the laws of physics.
