Jean-Baptiste Lamarck proposed that organisms could pass on to their offspring traits that where acquired during their lifetime. This has come to be known as inheritance of acquired characteristics.

On the other hand Charles Darwin recognized the main mechanism for evolution: Natural Selection. Natural Selection is the process by which favorable heritable traits become more common in successive generations of a population and unfavorable heritable traits become less common, due to differential reproduction. That is: given a certain population, those individuals who are more fit to the selective pressure(s) by their habitat (in a given time and space) will leave more descendants than those less fit

In short, Lamarck thought that changes were acquired during the life of a parent organism and thentransmitted to their offspring while Darwin deducted that changes were already present in the parent organisms, and that the best adapted to that situation survived to breed, which meant that those genetic changes become common in the following generations.

How is Darwin's theory of Evolution and Lamarck's theory of Evolution alike?

The primary difference between Darwin's and Lamarck's approaches to evolution (if I remember correctly) was that Darwin believed that evolution operated primarily through breeding and death: members of a species that have unproductive characteristics tend to die early and have less opportunity to produce offspring, and so their characteristics are not passed on to future generations. Lamarck, by contrast, thought that environmental conditions could exert a direct (if slight) influence on the genome, so that parents would tend to produce offspring that were better suited to the environment they lived in. For example, Darwin would explain the thick fur and subcutaneous fat deposits of cold-climate animals by saying that members of the species with less fur and fat would die more easily and earlier in cold weather; Lamarck would explain the same result by saying that the cold climate induced the organisms to produce more fur and fat, and their offspring would be born with a greater capacity to produce those things than their parents. Lamarck's theory has not been disproved - scientists still do not have a clear understanding of the process of evolution - but for various non-scientific reasons it is less accepted in the scientific community (primarily, I think, because it opens the door to a teleological argument abut the nature of species that most scientists find distasteful). It is important to point out that Darwin's theory was that of Natural Selection and The Origin of Species, and he was not proposing any system separate from or one that discredited classical Creationist theory. Jean-Baptiste Lamarck, however, coined the phrase Evolution.


Was Lamarck's theory correct?

Lamarck was correct about the connection between the environment and evolution. He saw that the organism changes based on the environment and its survival. However, Lamarck is not well-known for his advances in the field. Instead, he is known for the incorrect mechanisms for evolution that he proposed, including "use and disuse" and "inheritance of acquired characteristics." (A small note, Lamarck definitely did not have a "theory," he had hypotheses).

What did Jean Baptiste Lamarck discover?

Jean Baptiste Lamarck proposed the theory of inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to its offspring. He also investigated the relationship between organisms and their environment, contributing to our understanding of evolution.


What is the difference between the lamarack and Charles Darwin theory of evolution?

The mechanisms for evolution. Lamark had a concept called acquired characteristics, an organism " needed " to evolve and any development of the organism, say developed muscles, could be passed on to progeny. Darwin's theory showed all organisms as variants and those with the best adaptions to their environment were reproductively successful and passed these traits on to progeny and over time the population evolved.


What are similarities between Darwin's theory and Lamarck's theory of evolution?

They both propose that organisms are not immutable, but changes over time. However the mechanisms of the two theories are very different.

What is the difference between theory of evolution and biological evolution?

The theory of evolution is the overarching scientific framework that explains how biological evolution occurs. Biological evolution refers specifically to the change in inherited characteristics of populations over generations. Biological evolution is the observed process that supports the theory of evolution.


What is the difference between the theory of language and evolution?

Theory of evolution refers to animals and plants evolution along the time. Language evolution is another issue, not entirely related to the theory of evolution. It follows the theory of evolution on some way but it is related to culture evolution, not to the physical attributes evolution.


What is the difference between evolution and theories of evolution?

Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.

Difference between the evolution of man and the evolution of apes?

Man is an ape. The evolution of one is the evolution of the other. Genetics in a particular immediate environment and reproductive isolation leads to the variences in two species that share very recent common ancestors.
