No, unless the mechanisms by which these traits are acquired are inherited, subject to variation, and found in patterns of nested hierarchies.

Why was Lamarck's theory of evolution not eccepted?
Not well supported by the evidence and basically just assertion. Lamarck asserted that acquired characteristics, such as muscles developed during one's lifetime, were heritable. They are not. He also asserted that an organism had a " desire " to evolve. This was also not true.
Has Lamarck's theory of evolution been proved?
Scientists do not prove things. Lamarck's theory is long refuted as acquired characteristics and the use and disuse concepts are not explanations for evolution of populations.
What question did both Lamarck and Darwin try to answer with their theories of evolution?
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
Why is Darwin's theory of evolution better than Lamrack's?
Darwin's explanation for the fact of evolution was better than Lamarck's explanation and fit the fact of evolution. Natural selection solved much of the species problem, but acquired characteristics did not have the empirical support and explained nothing in the end.
What are Darwin vs lamarck theories?
Lamarck Posited the concept of acquired characteristics being heritable and the organisms " need " to adapt physiological parts, such as giraffes " needing " longer necks. Needless to say both of these main concepts of Lamarck's were wrong. Darwin posited the theory of evolution by natural selection that saw selected variations of organisms evolving over time by their progeny inheriting favorable characteristics. Darwin had the evidence that Lamarck did not and his theory, with modifications, is still the best explanation of evolution and the origin of species extant.
Acquired characteristics lead to evolution?
what evolution as a result of acquired characteristics
What was wrong with lamarck's theory of evolution'?
His two main concepts, acquired characteristics and a innate " desire " to evolve, were both unsupported by any evidence and were not the way evolution happens. So, Lamarck's " theory " ( in the vulgar sense ) was utterly refuted by the actual evidence and process of evolution.
Does acquired characteristics lead to evolution?
No, acquired characteristics, such as building muscles through exercise, can not be passed onto the progeny and thus allele can not change over time in populations from acquired characteristics. The are not " hard " heritability.
Why doesn't evolution occur through the inheritance of acquired characteristics?
Because acquired characteristics are not programmed in the DNA; only characterisitics which are genetically programmed are passed on and inherited.
Whose theory of evolution conflict with Darwin's theory of evolution?
Lamark's theory perhaps. Acquired characteristics clash with heredity.
Theory of Evolution by Inheritance of Acquired Characteristics?
This is the theory of Lamarck and it is long refuted.
Jean Lamarck?
French naturalist who proposed that evolution resulted from the inheritance of acquired characteristics (1744-1829)
How do organisms change over time?
The evolution of a organism depends on what type of organism it is

What are the differences of evolution and theory of evolution?
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.
