RossInheritance of acquired characteristics. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, leading to evolutionary change. This mechanism has been largely discredited in modern evolutionary Biology, with natural selection being the predominant mechanism for driving evolution.

What were the two ideas proposed by Lamarck to explain the mechanism of evolution?
Jean-Baptiste Lamarck proposed two ideas to explain the mechanism of evolution: the inheritance of acquired traits and the use and disuse of organs. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, and that the use or disuse of certain organs could lead to changes in those organs over time.
What are the same between Darwin and lamarck?
Darwin and Lamarck were both influential figures in the field of evolutionary biology. They both proposed theories about how species change over time: Lamarck suggested that acquired traits could be inherited, while Darwin proposed natural selection as the mechanism for evolution. However, Darwin's theory has since become widely accepted, while Lamarck's ideas have been largely discredited.
Which of the foWhich of the following would describe Lamarck and ideas about evolutionllowing would describe Lamarck and ideas about evolution?
Lamarck proposed the idea of "inheritance of acquired characteristics," suggesting that organisms can pass on traits acquired during their lifetime to their offspring. He believed that these acquired traits could lead to evolutionary change over time. However, his ideas have largely been discredited in favor of Darwin's theory of natural selection as the primary mechanism of evolution.
Stated that inheritance of acquired traits caused change in a species over time?
This statement is incorrect. Inheritance of acquired traits, as proposed by Jean-Baptiste Lamarck, is not a valid mechanism for evolution. Evolution occurs through natural selection acting on genetic variations already present in a population, not through the direct inheritance of acquired characteristics.
Who was the first to recognize the role of the environment as a significant factor in evolutionary change?
The scientist who first recognized the role of the environment in evolutionary change was Jean-Baptiste Lamarck. He proposed the theory of inheritance of acquired characteristics, suggesting that organisms can adapt to their environment during their lifetime and pass these acquired traits to their offspring.
