Maxwell and Lamarckism — the value of information

The physicist Maxwell famously devised a thought experiment where he postulated that a demon could sort the atoms, hence violating the second law of thermodynamics (2TD). The 2TD states that entropy must always increase as warm and cold particles will mix. It is one of the few laws, if not the only one, that has an arrow of time.

The Lamarckian (anti-Darwinian) view in biology is that an ancestor can pass on selected acquired genes/traits to its descendants, hence leading to an improvement in traits.

Both of these concepts are similar in that they have an invisible hand of information that can sort and select atoms or genes. The truth is though that there is no hand but that randomness (entropy) rules. In the case of evolution, the fit survive and thrive because their random mutations bring surprise improvements.
