On the Origin of Species

Sun, 21 Jul 2024 00:00:00 +0000

Every species produces far more offspring than can ever survive. Pair that with two more facts — individuals within a population vary slightly, and they pass their traits to their young — and you have the engine that built the living world. Across immense stretches of time, tiny inherited advantages accumulate, generation after generation, until they add up to new species, to organs as intricate as the eye, and to the deep anatomical kinship running through all life. Darwin called this process natural selection, and his argument is that it accounts for the diversity and fit of living things without any need for separate acts of creation.

Entangled Life

A mushroom is just the fruit. The organism itself is a web — mycelium, a mesh of fine filaments called hyphae that threads through soil, wood, and the bodies of other creatures. Merlin Sheldrake’s argument is that fungi quietly demolish one of our most basic assumptions: that life comes packaged as separate, self-contained individuals. Mycelium has no brain, no center, no body plan, yet it solves problems, trades goods, and manipulates animals. Follow the fungi and the neat boundary around “an organism” starts to dissolve.

Other Minds

The octopus is the closest thing to an intelligent alien we’re ever likely to meet, and it grew its mind almost entirely apart from ours. Six hundred million years ago the lineage that leads to us and the lineage that leads to cephalopods split off from a shared ancestor barely more sophisticated than a worm. From that near-nothing, two utterly different body plans arrived at genuine cognition — proof, Peter Godfrey-Smith argues, that a mind is not a one-time invention. Awareness evolved more than once, and it did so along a gradient rather than switching on at some magic threshold.
