Jean-Baptiste LaMarck's evolution theories included soft inheritance, Lamarckism. The idea that an organism can pass on characteristics it acquired during it's lifetime onto it's offspring, a use/disuse theory(i.e., burrowing animals such as a mole now have small eyes due to disuse).
In 1801, he published a major work in the classification of invertebrates, a term he coined. In 1802, he was one of the first scientists to use the term Biology in modern sense.

What is the book written by Lamarck?
Lamarck wrote the three-volume Flora Française, and a few years later the Système des Animaux Sans Vertèbres. If just one of these two monumental undertakings is not enough to put this remarkable investigator into the top of the ranks of the naturalists, then no one belongs there.Are you a student of biology, either the general science of any of its more specific branches?

Which describes Lamarck's explanation for changes in the fossil record?
Lamarck's explanation of evolution is based on two principles: use and disuse and the inheritance of acquired characteristics. Lamarck's "use and disuse" principle explained his belief that the body parts that are commonly used become larger and stronger such as a giraffe's neck, while those that are not used deteriorate and become smaller. He also believed that an organism could pass these modifications to its offspring through the inheritance of acquired characteristics. Thus, Lamarck thought that evolution is driven by the innate drive of organisms to become more complex. Although he was later proven wrong, he was insightful in observing and recognizing that gradual evolutionary change does exist.
What theory of evolution did lamarck develop in 1809?
Jean Lamarck's theory of evolution is known as zoological philosophy or the inheritance of acquired characteristics, and stated that changes to an organisms phenotype (basically what it looks like) will cause changes to it's genotype (DNA). This has been disproved of by modern scientists, with natural selection as the main theory.
How could a water bird acquire long legs Lamarck?
According to Lamarck's theory of inheritance of acquired characteristics, a water bird could acquire long legs through its efforts to adapt to its environment. For instance, if the bird frequently waded through deeper waters, it might stretch its legs over generations to reach the bottom for food, leading to longer legs. These acquired traits would then be passed on to its offspring, resulting in a population of water birds with longer legs over time. However, it's important to note that Lamarck's ideas have largely been replaced by Darwinian evolution and genetics.
If Lamarck's hypothesis of species modification were true the child of a person who developed large muscles by lifting weights would be born with?
According to Lamarck's hypothesis, the child would inherit the acquired trait of large muscles from the parent who developed them. Therefore, the child would also have a tendency to develop large muscles.
What was lamarck's first name?

Where did Darwin meet Lamarck?
Darwin did not actually meet Lamarck in person. Lamarck's ideas on evolution were published before Darwin's time, and Darwin was familiar with them through his readings. Darwin's theory of natural selection differed from Lamarck's theory of inheritance of acquired characteristics.
What did lamarck propose a scientific explanation for?
Lamarck hypothesized that organisms evolved through the inhertitance of acquired charactaristics.
When was Lamarck's theory of evolution published?
Lamarck's hypotheses were published in Zoological Philosophical Work written in 1809.

What idea did Lamarck and William smith contribute to the study of fossils?
Lamarck's ideas were that he had a great contribution to the study of evolution.
Why does jean-baptiste lamarck's theory was not immediately accepted by the public?
The public, due mostly to religious reasons, was not ready for any transmutational theory and Lamarck's theory had no evidence to support it thus scientists of the time did not pay it much attention. Also Cuvier was Lamarck's enemy and denigrated the theory Lamarck developed.
