Central to Lamarck's theory was the idea that evolution was a progressive process, moving towards ever greater complexity and ever greater perfection of adaptations. If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. Blacksmiths tend to have extremely large arms developed from years of using their heavy hammers. If the theory of inheritance of acquired character proposed by Lamarck would have been true than offspring's born later in parents' life would have better acquired characters and would be more advanced than offspring's that were born earlier. For example, giraffes developed elongated long necks as they stretched to feed on the leaves of high trees, an acquired advantage that was inherited .

Acquired characters (or modifications) developed by individuals during their own lifetime are inheritable and accumulate over a period of time resulting a new species. However, Lamarck's theory of the inheritance of acquired characteristics was disputed by many biologists because more and more evidence demonstrated that traits and behaviors were the result of natural selection and controlled by genes. . He also developed a theory for the mechanism by which changes in the soma might be transmitted to the germline cells, sperm and eggs.
In an early theory of evolution, Jean Baptiste Larmarck (1744-1829) proposed that species evolve when individuals adapt to their environment and transmit those acquired traits to their offspring.

He proposed that organisms are not fixed and they evolve from the pre-existing organisms by modifications. Evidences in favour of Lamarckism 1. He suggested that all cells in an organism are capable of shedding minute particles he called gemmules, which are able to circulate throughout the body and finally congregate in the gonads. This was indeed an idea that he endorsed, but he did not claim it as his own nor did he give it much thought.
