Why do textbooks use peppered moths camouflaged on tree trunks as evidence for natural selection?

Question

When biologists have known since the 1980's that the moths don't normally rest on tree trunks, and all the pictures have been staged?

Here is a list of texbooks this morepresentation appears in, Buton S Gutman biology Magraw Hill 1999 George B. Johnsons Biology Orlando Florida Rinehart and winston 1998 Slyvia Mader, Biology sixth edition magraw Hill 1998 kenneth R.

Wardog I am dissapointed that you care so little how truth is handled. I am however not really suprised.

Jen I am talking about what your science calss is teaching you not any relgious book. I thought science was supposed to be interested in facts.

Spud the books I have listed are not that old. And are you seriously suggesting is't okay to fudge data becaue it provides strong visual data. Strong visual data for what a fake? do you really approve of being duped?

God fear these are separate issues. But you are quite right if you wish to suggest the crucifixion was a fake you are more thn entitled to. However yur science class doesn't present it to you as truth spending our tax dollars. As far as the crucifixion goes the burden would then be on you to present evidence. Which I should add I have studied to some degree. In fact you may be the one to be suprised that many of the top legal minds in history have come out in favour of the crucifixion. As a historical fact independantly verified by a number of witnesses both in and out of the Christian faith. If you need any referances I can give plenty. But I doubt your up for the challenge.

According to University of Chicago evolutionary biologist Jerry Coyne in his review in Nature 1998 from time to time evolutionists re-examine a classic experiment and find to their horror is flawed or down right wrong. According to Coyne the fact that peppered moths do not rest on tree trunks alone invalidates kettlewell's release and re-capture ex-periments, as moths were released by placing them directly on to tree trunks. Coyne concluded that the prize horse in our stable of examples was in bad shape, and, while not yet ready for the glue factory, needs serious attention. Especially in need of attention, argued Coyne, are the selective factors responsible for industrial melanism. we must stop pretending that we understand the course of natural selection just because we know one trait is more fit than another".

Answer 1

Because they are trying to prove theoretical exhistance to something that doesnt.

Answer 2

First of all Natural Selection does not go against the teachings of the Christian religion. now to answer the question. The moths don't have to be resting on tree trunks for this example of natural selection to work, they can be resting on buildings as well. In industrial parts of Europe, a moth that is normally white has a recessive gene for the colour black. When the buildings in the city are covered by black dust due to the factories, the moths that express the trait for the colour black survive. The white moths in turn are seen by birds more easily and are quickly eaten; the white moths then drastically go down in numbers. This shows the main basis for Natural Selection in the environment. Oh and this actually does happen, scientists don't stage this phenomenon.

Answer 3

as an instance a level. in case you want this one, who does a mom scream in the starting up; the boy sitting on the settee watching television or the single which has hidden in the back of the chair to observe, understanding that this can take position? the total factor is that the ingredient that is maximum obtrusive receives wiped out first, giving different, more healthful organisms time to flee and spread their trait, no longer that moths magically seem on timber.

Answer 4

What textbooks are you referring to? I admit I haven't taken a biology class since freshman year of college, but I don't recall any of the things you're mentioning being used as evidence for evolution.

Answer 5

The whole landscape, not just trees became darker. It's not that big of a stretch to think that if a peppered moth is camouflaged better on a dark tree, it ought to be camouflaged better in a darker landscape as well.

Answer 6

The moths were one of Darwin's original observations which led to his theory of evolution. Modern pictures might be staged, but the original observations were quite real. Evolution has been established science for a century and is now proven fact.

Answer 7

Maybe because the text books are outdated, or maybe because it's such strong visual image that nothing else can convey the same idea as well.

Answer 8

as a christian, even i have to admit that this makes sense not only from a religous point of view, but especially as one where a mutation becomes a genus.

Answer 9

No one can force you to believe anything.

Why, I could say that the whole Crucifixion was fake but you wouldn't believe me.

Answer 10

How many of these stupid questions are you going to ask? We understand that you don't like how textbooks present evolution. Get over it.
