Explain why naural selection does not move in a pre-determined direction?

Answer 1

Imagine that you are trying to determine what path to take, but you can only see the one step in front of you at a time. You choose that step based on which one looks best, then you can see the next one. You can't possibly determine which step to take based on the outcome.

Natural selection cannot see the end product, so each step needs to have benefit in order to be selected.

Answer 2

Natural selection, while attempting to adapt living organisms more efficiently to existing conditions, also must contend with the law of entropy, which is the exception that proves the rule.

In other words, many mutations are negative or debilitating, but capricious changes in environment can change the value of a particular mutation for a certain environment and make that differentiator a net positive for the organism. This tension between the two forces creates the diversity that we see.

Answer 3

Natural selection is the process that weeds out individuals unfit for their environment, and thus leaves more fit individuals to produce offspring. However, the environment is in a constant state of flux, and as the environment changes, so too will the traits (and individuals that have them) that are best suited for it.

Answer 4

>"organic decision" skill "Random effect." Demonstrating how badly you realize a idea does no longer "disprove" it. >"decision skill "this, as a replace of that." it continually calls for a selector." thus nature is the 'selector' ... for this reason 'organic decision'. a foul iciness *selects* the rabbits with the most fur. those with a lot less fur do not live to inform the tale besides. So that is obviously no longer actual that "decision is an intentional act." ... till you assert that 'iciness' is able to "reason." you're making the mistakes of focusing on the *be conscious* decision, putting apart a particular that signifies that you've in concepts (as a replace of the overall which skill by technique of which that is utilized) as a replace of the concept ITSELF. >"properly if one become to take a bag finished of scrabble block letters and then pour them out of the bag many situations, it would want to by no skill write a Shakespeare's play." it would want to if there become some reason ... some selective pressure ... by technique of which Shakesperean words survived more suitable ideal than non-Shakesperean words. with out this style of selective pressure, your social gathering loses any resemblance by any skill to organic decision. >"a baby can see a construction and comprehend that a builder placed it there." provided that the infant has *earlier* expertise of beings noted as 'builders' that exist, and performance been everyday to create 'homes'. in the different case, no. >"in basic terms imagine the first male dogs and the first lady dogs attempting to discover one yet another to easily to reproduce " in basic terms imagine easily attempting to appreciate evolution before offering this style of ludicrous expertise of ways evolution works! >"evolutions significant concept is meant to be progression by technique of technique of organic decision, " No that isn't any longer. provide up attempting to declare issues about a idea (evolution) that you obviously do no longer understand. >"because Darwin's e book, The foundation of the Species, technological expertise has no longer produced one demonstrable shown info of evolution. " definite it has. yet you're searching contained in the incorrect places for such info. once you pass in basic terms to internet web pages that scrub themselves sparkling of any "info" of evolution, why are you shocked no longer to discover any. look ... you won't be able to "refute" something you won't be able to understand. and also you so obviously fail to appreciate evolution in even a RUDIMENTARY way. you have not disproved evolution. you've in basic terms proved that you do not realize it. .... in any respect.
