Darwin's. Duh.
Lamarck believed in evolution by acquired traits; i.e., if a blacksmith hammers all day, his arm becomes strong. By Lamarck's theory, the blacksmith's strength would be transferred to his offspring, but this is never observed.
Lamarck believed that traits acquired by one individual, will be immediately passed down on it's descendants. FE: If your father was a smith, you will have stronger muscles and bigger hands. Which is not true because evolution like that happens over thousands maybe millions of years and genetic changes are only expressed if the mutations occur in the DNA of the reproductivecells (spermproducingcells etc) Note: Lamarck has proven to be right by scientist nowadays in the point of genetic expression: Children of people who survived the Hunger Winter in Holland of 1944 have more chance on heart diseases and become thicker more easily. This change is directed to the fact that certain events can activate certain genes, thus stating that Lamarck's theory isn't entirely wrong
Lamarck was the first to create a theory of evolution. He pretty much stated that animals changed over time because they INHERITED their new trait that they had to have to survive. This was disproved. Charles Darwin found that animals changed due to NATURAL SELECTION. Natural selection is the process in which animals with a certain trait key to survival would survive in their environment and produce offspring more often than the ones without the new trait therefore passing it on to the next generation, and the next one.

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.

Darwin's theory made more sense and was proven true.
no the theory of evolution is a species becoming more advanced not over populated
I quote: "The Multiverse Theory". Any credible website can be unsecure. However there are a lot of people working around the clock to make these credible websites even more secure.
There was more than one astronomer who agreed with the heliocentric theory and was imprisoned for his investigations. The astronomers were Copernicus, John Dalton, Lamarck, and Galileo.
August Weismann but actually this theory of his was wrong....... Lamarck's idea was more appropriate...........
The Darwin's theory of natural selection emphasizes that the organisms of the same species with more beneficial traits survive while the others die off.
more credible, most credible
Darwin's Theory of Evolution states that organisms make small changes over time to adapt to their environment. For example, humans have evolved to be more intelligent and polar bears have a layer of fat to keep them warm.
Charls Darwins' theory of "struggle for existance and survival of the fittest"
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's 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.
It would probably be superseded by a thesis founded on more credible scientific evidence.
