Invasion of the land. An early lobe-finned fish from about 385 million years ago; a land dwelling tetrapod from Greenland, about 365 million years ago; and the transitional form’Tiktaalik roseae,’ from Ellesmere Island, about 375 million years ago. The intermediacy of Tiktaalik’s body form is mirrored by the intermediacy of its limbs, which have a bone structure in between that of the sturdy fins of the lobe-finned fish and the even sturdiest walking mammals: the bone with darkest shading will become our humerus, and the medium- and light-shaded bones will become the radius and ulna, respectively.

A Synapse

12 Jul 2020 2 80
At a presynaptic terminal (top) small vesicles twenty or thirty nanometers in diameter filled with neurotransmitter molecules are waiting. Arrival of an action potential (or spike) induces a fusion of the membrane with some of the vesicles so that a neurotransmitter can diffuse into the synaptic cleft and reach receptors (not shown) at the other side, which then open ion channels they are attached to. A synapse becomes more or less efficient, like when vesicles get bigger or smaller, or more or fewer release sites become available, while postsynaptically the ion channels may increase or decrease iun number and stay open during a longer or shorter period of time. So most, though not all, of the active processes are happening in the pre- and postsynaptic membrane. The result is called learning.

I claim we anthropomorphize because guessing that the world is humanlike is a good bet. It is a bet because the world is uncertain , ambiguous, and in need of interpretation. It is a good bet because the most valuable interpretation usually are those that disclose the presence of the whatever is mot important to us. That usually is other humans. ~ Page 3 (intro) There are two standard explanations of anthropomorphism: that it comforts us and that it consists in using our good knowledge of ourselves to account for what we know less well. Although each explanation has some truth, neither is sufficient. Comfort does not explain anthropomorphism well because much anthropomorphism is uncomfortable. Reliance on self-knowledge does not explain it well either, because our knowledge of ourselves is no more reliable than knowledge of what is not ourselves. - Page 6 Anthropomorphism in Philosophy and Science, shows that anthropomorphism occurs even among philosophers and scientists, although they are its most consistent critics. Scientists in particular try to avoid it, but they must make a constant effort. Its cause here appears the same as elsewhere: we strive to understand our world by pursuing important possibilities, and humanlike forms and behaviors are the most important ones we know. ~ Page 7
