Lamarckian evolution is based on the notion that changes that happen to an organisms physiology are passed on when it reproduces. Taking this to an extreme to show why it has been discredited, a person who loses their arm during their childhood does not have babies that are born with one arm. With regard to cave fish, Lamarcks theory of evolution argues that they lose their eyes during their life, and pass on this "lack of eye-ness" to their offspring. Modern genetics has further dampened this idea, as acquired characteristics are not carried in genes.
Darwinian evolution argues that, at some point during the cave fishes history, a genetic mutation caused one to be born with no eyes (or more likely, one was born with slightly less functional eyes). These fish, due to the nature of their dark environment, would be at no disadvantage to their fully sighted brethren. Eyes can easily get infected or irritated, so nature may have favoured on the side of the eyeless ones. Over time blind cave fish became dominant, eventually reaching the pinnacle of existence by being discussed on the internet.
Hope that helps.

That is the theory of evolution-but it's only one of the theories.
"Cave" - the tunnel from Mordred's Laboratory to the dungeon : push through the wall, which is loose dirt. "Cave"- the volcano on the fire planet (see related question)
The purpose of the paleolithic cave paintings is not known. The evidence suggests that they were not merely decorations of living areas, since the caves in which they have been found do not have signs of ongoing habitation. Also, they are often in areas of caves that are not easily accessed. Some theories hold that they may have been a way of communicating with others, while other theories ascribe them a religious or ceremonial purpose.
Some theories claim that it is prehistoric communication. Others, however, claim that it is NOT prehistoric because documenting lifestyles in art is considered recorded history.

When the depth of trench is large or when the sub - soil is loose, the sides of the trench may cave in. The problem can be solved by adopting a suitable method of timbering.
Lamarck knew evolution was happening, his inaccuracies are in how he explained it. The first part of his theory is known as "use it or lose it" today. He said that use makes organs and structures bigger or more useful. Giraffes needed long necks, while blind cave fish lost their eyes. Darwin thought this idea was too simple, and replaced it with natural and sexual selection. The second major point Lamarck made was called acquired inherited traits. This means that traits that an organisms gets after it was born affects its offspring. This would mean that a bodybuilder would naturally get buff children, and that crabs that lost their claws would have clawless spawn. A famous experiment involving the mutilation of mice (which left their offspring unaffected) disproved this. Because of our knowledge of genetics, we say that variation is caused by mutations and not acquired traits.

A cavern is a large underground chamber that is formed naturally in rock by the process of erosion and dissolution. These spaces are typically found in limestone or other soluble rocks and are often characterized by unique formations such as stalactites and stalagmites created by mineral deposits. Caverns can vary in size from small passages to expansive rooms.
Cant get it n sapphire, firered, or leafgreen, but u can trade it 2 those games frum ruby aftr u find it in the cave of origin when team magma sets it loose... Oh yea, the cave of origin is in sootopolis...so youll need to surf and dive to get there...
Where the cave is answer question cave. This is answer to question which is clearly written out. Cave is where don't know cave.
