Why are required traits not directly related to the process of evolution?
Acquired traits. Because evolution is the change in allele frequency over time in a population of organisms and acquired traits, such as muscles built by working out, can not be inherited genetically ( by alleles ) so are not " hard " inheritance. Some things like methylation of genes are passed epigenetically, but this does not quite qualify as acquired traits.
Why are aquired traits unimportant in the process of evolution?
They are unimportant because they cannot be passed on.If i get a scar on my left arm that is a trait, because my DNA does not include the information 'have scar on left arm' my children will not have a scar. A third arm would be in my DNA and be passed on. But not if I just sowed one on.
What are some of the different theories of evolution?
There is only one central "theory of evolution", which is the theory of evolution by natural selection that Charles Darwin pioneered. There have been different theories in the past - such as Jean-baptise Lamarck's theory of acquired traits - but these lost their status of scientific theory when they were shown to be wrong.
What are acquired traits?
things you change about your appearance.
What is acquired traits?
Acquired traits are those characteristics of an organism that develop during life as a result of injury, illness or other life process. For instance, lameness and stiffness in older animals are acquired traits often caused by arthritis. In contrast, a congenital trait is one that is present at birth, such as lameness due to a bone that did not develop properly.
Why don't acquired traits result evolution?
Acquired traits are not passed along in the germ line, but die with the individual. Thus there is no change in allele frequency ( which is the definition of evolution ) which results in no evolution. Research epigenetics to find a type of acquired trait transferal.
How was Lamarc's theory of evolution wrong?
He incorporated the Acquired Traits theory into evolution, which Darwin's research proved as BS.

Are acquired characteristics evidence of evolution?
No, unless the mechanisms by which these traits are acquired are inherited, subject to variation, and found in patterns of nested hierarchies.
Which idea did lamarck propose that was rejected by his fellow scientists?
That organisms pass on traits acquired in their lifetimes. It was rejected in favour of Darwinian evolution, in which species and not individuals evolve, but Larmarckism is valid to a point where epigenetics is concerned.

What is the answer between acquired and inherited traits?
no, there are two types of behaviors: innate and learned. obviously, the innate behaviors are known from birth and the learned behaviors are acquired after birth. Learned behaviors can modify innate behaviors such as teaching a baby not to babble but to learn English. Simplified: something LEARNED cannot be passed down genetically UR A FAIL EAT CAKE
State lemarcks theory of evolution?
French biologist Jean-Baptiste Lamarck believed in the equilibrium of nature. His theory of evolution suggests that traits acquired by organism during its lifetime will be passed on to the offspring.
What are Lamarcks's contributions to evolution?
Two pertinent ideas of Lamarck were the idea of acquired characteristics and the concept of use and disuse. Acquired characteristics posited that some experience that an organisms went through in life, such as muscle building due to hard work, would be heritable. Use and disuse posited that certain organs and traits could develop through use, such as the giraffe trying to eat the leaves on the heights of trees, or that organs or traits could be lost through disuse.
How would vestigial traits be explained if evolution occurred via inheritance of acquired characters as proposed by Lamarck?
as a change in an individual's phenotype in response to an environmental challenge
Briefly describe two ideas about evolution that were proposed by scientist in the 18th century?
Darwin Which was the theory of evolution by natural selection. this is where the fittest species survive and pass on their traits. Lamarack which is the theory acquired characteristics . similar but wrong where it states animals will adapt and chage there thraist to fit in the environment and pass on their traits
What kind of traits are traits that people deliberately change?
manipulated acquired traits
