I recently read this:
The evolutionists state that everything changes or, just evolved by needs over time, well this could be for some simple things but for the various reproduction methods of animals over time; this is very questionable… This still doesn’t explain why some species would even think of changing, or want to change, or need to change… Lets look at the last “needs ” to change, due to the environment, etc. ; well first since the evolutionist state that the change would take place over millions of years… Thus an animal needing more, fur, or gills, or wings would not have time before the environment caught up and they would die out… It would take too much time for them to adapt or change into what ever new forms; much less getting their biology to cooperate and product a new creature… It is a rather drawn out argument you must admit… But for the sake of argument we will let them have their turn at bat… We will say it happened, that way… OK!!
The above was written by a creationist. This is what I think:
I agree with the author in that environmental changes happen too quickly for biological changes to catch up. Evolution does not chase change requirements, rather species are already where they need to be when the change is necessitated. I believe as do scientists that all species (including human) are varied and various groups within a species can differ from one another and still be the same species.
I’ll give an example. All members of a species differ somewhat. Some are brighter colored, some have larger appendages, more fur, etc. An example would be body hair. Some human males have far more than others. We can see this and prove this.
I also think that when an environmental change occurs which ever group is best prepared will survive. Let’s say a species of wolf inhabits the central US. Of this species a genetic mutation has occured that has spread through half of the total number. That mutation is the undercoat of half the species is thinner and less dense than the other half. Both varients can readily survive in the temperate climate of the midwest. However, should the climate become extremely hot (tropical) or cold (artic) then one of the halves will be more ready to adapt to the new environment and may in fact be the half to survive.
The author is wrong in his supposition that biological change chases and follows environmental change. Environmental change occurs far to fast for any biology that I am aware of to make the necessary changes. Evolution is haphazard. Only those that are ready for the change will survive and being ready for the change is based on the luck of having the correct gene mutation. In fact, none of the species may be ready and all will perish.
