Jean-Baptiste Lamarck is best known for developing one of the earliest theories of evolution, known as Lamarckism, which proposed that organisms could pass on traits acquired during their lifetime to their offspring. He also contributed significantly to the field of invertebrate taxonomy, classifying numerous invertebrate species and laying the groundwork for future studies in Biology. His ideas, although largely superseded by Darwinian evolution, sparked important discussions about adaptation and inheritance.

Was lamarcks idea of acquired traits proven or rejected?

rejected.


Which of lamarcks ideas was later found to be incorrect?

The idea of acquired characteristics. For instance. The idea that a blacksmith, who would develop enormous muscles due to his trade, could pass these physical attributes on to his children.


Did Darwin observed the greatest diversity of organisms on the Galapagos Islands?

Yes, it was one of his biggest accomplishments.


What were the lamarcks two theories of how organisms evolved?

Concepts more than theories. Use and disuse. A anatomical part of an organism would fade away if not constantly used and would enhance itself is used. The giraffe neck as an example of use. Acquired characteristics. Characteristics that one developed over the course of a lifetime could be passed on to progeny. Such as the developed muscles of a blacksmith could be inherited by his children. Naturally, both these concepts were absolutely refuted by the theory of evolution by natural selection.


What was Lamarcks theory of how things changed over time?

Lamarck's theory, known as Lamarckism, proposed that organisms evolve through the inheritance of acquired characteristics. He suggested that traits developed during an organism's lifetime, such as a giraffe stretching its neck to reach higher leaves, could be passed on to its offspring. This idea emphasized the role of adaptation to the environment in driving evolutionary change. While Lamarck's theory was influential, it has since been largely discredited in favor of Darwinian evolution and natural selection.
