2. Lamark contributed to the scientific community in numerous ways but began by being one of the first to propose that humans evolved from a lower species through adaptions over time. Although his primary theory was was proved wrong, he continued making observations and with his explanations he combined, this lead to having a new process of thinking which has made an impact of Darwin and had him inspired. Jean-Baptiste's evolution theory started out as very simple however it eventually built up until it was created into a complex human form. He believed that if an organism changed during life it's life in order to adapt to its environment, those changes will then be passed on to its offspring. His thought on change was that it is made by what the organisms want or need. Another theory of his was that the body parts that are not being used will gradually be disappearing. Lamarck's additional beliefs of evolution was that it happens based on a plan which leads to having the results already been decided.
3. The concept that was most affected by Lamark's work was the evolutionary concept if the environment changes, the traits that are helpful or adaptive to that environment will be different. Despite being proved wrong, his hypotheses and observations is what began the study of different species and their ability to adapt to the environment. This lead to discovering the new adaptive traits that will have a higher reproductive success than others, not only that, but the new traits will spread which will have an impact in the population. This is the process of natural selection; the natural environment selecting the organisms that will be the most successful.
4. Although many of Darwin's theories have been supported by a numerous amount of evidence, it is possible that Darwin may have developed his theory of natural selection without the work of Lamarck. I'm sure there are many others who have the same idea or thoughts but don't have a sufficient evidence to support their theories. Anyone can be influenced by anyone's work, even if their ideas have not been proven. As for Lamarck, despite being proved wrong, his ideas and thoughts could have been an influence on Darwin. Darwin and Lamark both thought that life had changed gradually over time and was still changing and that living things change in order to adapt to their environments. They both could have approached their ideas differently and receive different results, but it is possible that they may have been influenced by each other or even others.
5. The attitude of the church affected Darwin and his publication. Darwin was not only questioned but he was also criticized when he came out with his publication "On the Origin of Species." His theories and ideas of evolution was received as a disrespect because he was going against the belief of the church's belief of God's work or creation. This is the reason why Darwin kept holding his publication back because he was aware of what might occur when others saw his work. What he predicted came true but Darwin also received a lot of praise for his work.
