Chapter Three is a parable about how forests provide lessons for society. The surprising observation that a chaotic wild forest can grow more timber than a managed plantation reflects how trees have evolved to cooperate, and how diversity and complexity offer protection from risk. Forest science devoted to maximising yield may obviously be better for producing identical commercial logs, but the monoculture of a plantation means the trees lose benefits from their natural evolution, notably the ability to cooperate through underground fungal networks. It reminds me of the modern culture of individualism, where competition between people is thought to deliver the best results but appears to have lost many of the benefits from traditional societies.
Calling trees "creatures" reflects the origin of the word creature as any living organism, although this word has evolved into 'critter' which excludes plants.
Group versus individual selection is the main theme of Wilson's The Social Conquest of Earth, as I mentioned. I have found the arguments for group selection compelling, whereas the arguments against it from Richard Dawkins and other biologists appear based more on emotion than reason.
ChatGPT gives this helpful summary of the mainstream view.
The Hidden Life of Trees seems to provide strong evidence for group selection, with the forest operating as a super organism to advantage traits that benefit the forest as a whole rather than individual trees.The question of whether group selection is possible in natural evolution is a subject of debate among biologists. Group selection is the idea that evolution can act on groups of organisms, rather than just individuals, and that traits that benefit the group as a whole can be favored even if they are detrimental to individual fitness.
While there are some examples of group-level selection in nature, many biologists believe that individual selection is the primary driver of evolution. This is because natural selection acts on individual organisms, which compete with one another for limited resources and reproductive opportunities. Traits that confer an advantage to individual fitness are more likely to be passed on to future generations than those that do not, even if they may be beneficial to the group as a whole.
Some biologists have proposed that group selection may play a role in certain circumstances, such as when populations are small or when there is a high degree of relatedness between individuals. However, the majority of evolutionary biologists believe that individual selection is the most important force driving evolution, and that group selection is a relatively rare occurrence.
