the broken watch (the 2nd law vs. evolution) part 1

I explain how populations decay genetically over time and how the 2nd law thermodynamics plays a role. macro evolution is impossible since marco evolution is small changes over great periods of time because of the decay rate .

Do you always get this many dislikes? 

[spark300c]

@divud123 no but this controversial topics. really most of viewers seem never debate about mechanics. Plus people do not like paradoxes will try solve it or say gain knowledge was in error or false or incomplete.

The second law ALSO does not state that entropy decreases always. It states that it ALMOST always decreases. Therefore all these problems are solved with large tracts of time, which we have evidence for.

[spark300c]

@fresheyeball the second law states that in system which is the universe that amount of entropy stays the same or increases. natural nature of system is to head to disorderliness. in order for there be order increase entropy must increase some else. car, computer softer ware and many other systems experience changes it usually change to disorderliness. it take energy to repair these things and energy is dissipated as heat so that that amount of entropy stays the same.

"Most mutations are bad mutations and beneficial mutations are rare."

Hmm, interesting, given that:

Most organisms die before they can reproduce. Animals that live to reproduce are rare. *

*(compared to the number that are become an organism (i.e. fertilised)).

That would fit with evolution then.

@St00sh13 it a noise to signal ratio. not all bad mutation get selected out . if most of the population had slightly bad mutations they all reproduce at same amount then in for trouble. sensitivity of natural selection depends on fertility rates ,population size and genome size. selective pressure is like having a budget. budget can not pay for all expensive then things deteriorate. to evolve to more advance form or adapt a larger budget or pressure is needed. it about the numbers.

[fresheyeball]

@spark300c No it doesn't. The second law of thermodynamics is an expression of the tendency that over time, differences in temperature, pressure, and chemical potential equilibrate in an isolated physical system.

It says nothing about the universe as a system. It says nothing about earth (which is not an isolated system). And it says TENDS TO.

A bar of metal is just a very, very inefficient engine, if you are comparing it to an engine. Otherwise it's just a bar of metal.
