And, what's more, it only applies to systems that aren't receiving energy from outside and Earth is clearly not one of those.A Series on Biological Information: New Perspectives The second law is only a statement about the general state of a system - it allows for localised decrease of entropy so long as there's appropriate increase elsewhere in the system.

In reality, as these fine redditors have explained, this is not the case. Surely these two things run directly contradictory to one another - or so certain people would wish you to believe. So here we have the theory of evolution which is misunderstood as life reaching greater and greater levels of complexity or order and the second law of thermodynamics which is misunderstood as systems reaching greater and greater levels of entropy or disorder. Suffice it to say that life is an ordered thing rather than a disordered one. I mean, you never see algae cells by themselves do you? Luckily for us, whether or not this counts as complexity turns out not to matter. Does putting more cells together make something more complex? Kind of, but not in the same way. Numerousness isn't really the same as complexity though - just compare this animal cell to this amoeba. It's also easy to see how people who think that way would describe life as having started simple and gotten increasingly complex. But it's easy to see how people can fall into thinking that life started with single cells and just kept adding more cells. Does this mean that single-celled life isn't around any more? No.

We understand that some of the earliest forms of life had only one or two cells and we can see that the planet today is full of much larger creatures than that. We've gone from the intuitive 'systems eventually stop working if you stop putting energy in' to the sneakily dangerous 'everything gets more and more chaotic all the time'.Д«ut how does this relate to evolution? Here we have yet more misunderstandings. The disorder of a n isolated system which isn't completely random will inevitably increase over time, approaching a maximum value when it's completely random.ДЄt this point we've abandoned a lot of the meaning of our original understanding in order to reach something that's much easier to pack into a sound-byte. If we're even more incautious, we might get rid of the parts that seem confusing or redundant: The entropy disorder of an isolated system not in equilibrium which isn't completely random will tend to inevitably increase over time, approaching a maximum value at equilibrium when it's completely random. Now, these are true but if we're not careful about it then injecting them into the explanation above - like I did with the first definition - will give us the wrong idea about the second law: Inevitable and steady deterioration of a system or society. Notice how I used the first definition in the dictionary link above? Check out the second and fifth ones:ДЄ measure of the disorder or randomness in a closed system. This is starting to make sense! We can see that when a system is closed off, eventually it will stop working but we can keep a system working if we constantly send energy into it. So, the less energy a system has available for work, the closer that system gets to doing no work at all. Here, ' equilibrium' means the system has reached a state that can't change unless something else comes along to change it and ' entropy' is the amount of energy not available to do work. The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium. A simpler way to put it is given here by Rudolph Clausius: If you check the wiki page, you'll find the law stated in a variety of ways and it can be hard to figure out how they're all supposed to be expressions of the same thing. The second law of thermodynamics governs the entropy of a closed system but a lot of people manage to misunderstand what this means. I'm going to have a go at explaining it but first I have to explain the parts. These guys have done a fine job of explaining the answer but what it seems you're really asking for is an explanation of the question.
