Lamark believed in the theory of acquired traits. He thought that if you broke your leg or dyed you hair, than your offspring would have that trait as well. Now, Lamark looked at a model of a giraffe. He thought that giraffes started out short and their low-to-the-ground food source died out, so they had to look in trees. He thought that they stretched their necks and their offspring had that trait. You can compare this to breaking your leg or dying your hair because it is only a temporary thing, not like blue eyes or brown hair which has a likelihood of being passed down to your offspring.

What did lamarck think evolution involved that caused his ideas to be incorret?
Lamarck believed in the inheritance of acquired traits, where changes that an organism acquired during its lifetime could be passed on to its offspring. However, this idea is not supported by modern genetics. In reality, evolution is driven by natural selection acting on genetic variations.
What are lamarcks ideas?
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.

What did Lamark think evolution involved that caused his ideas to be incorrect?
Lamarck believed in the theory of inheritance of acquired traits, where individuals could pass on characteristics acquired during their lifetime to their offspring. However, this idea was proven incorrect as changes that occur in an individual during its lifetime are not passed on to offspring genetically. Instead, evolution operates through the process of natural selection acting on heritable traits.
What is Kimuras Neutral Theory of Molecular Evolution?
Kimura (1968) • The vast majority of evolutionary changes at the molecular level are caused by random drift of selectively neutral mutants (not affecting fitness) ! The Molecular Clock.
Stated that inheritance of acquired traits caused change in a species over time?
This statement is incorrect. Inheritance of acquired traits, as proposed by Jean-Baptiste Lamarck, is not a valid mechanism for evolution. Evolution occurs through natural selection acting on genetic variations already present in a population, not through the direct inheritance of acquired characteristics.

How can you believe in evolution and god?
You can believe evolution was caused by God and he controls it.
Is getting smarter evolution?
It could be, if it is caused by genetically inherited factors.
Who was the theory that the frequent use of an organ caused it to be enhanced was developed by?
The theory that the frequent use of an organ caused it to be enhanced was developed by Jean-Baptiste Lamarck, a French biologist. This theory is known as "Lamarckism" and suggests that acquired traits can be inherited.
How did evolution start?
The point of Evolution is that it doesn't start or stop at any given point. It's a natural process that happens throughout life. Evolution is caused by triggers in genes. Different animals have different triggers. These triggers can be caused by different things, but most commenly a change in habitat.

sexual reproduction
Can a stigmatism correct itself?
No, an astigmatism can not correct itself. This is because an astigmatism is caused by the shape of the eyeball.
