The mechanism for evolution that was proposed by Jean Baptiste Lamarck was that organisms began life as primitive forms but adapted to their environment and became more complex forms. He also claimed that as time progressed, new primitive organisms were also occurring, so that they may evolve in the future.

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 did Lamarck's and Darwin's hypotheses about evolution have in common?
Lamarck's and Darwin's hypotheses about evolution both emphasized the idea that species change over time in response to their environments. They acknowledged that organisms adapt to their surroundings, although Lamarck proposed that these adaptations could be passed on to offspring through use and disuse of traits, while Darwin introduced the concept of natural selection as the mechanism driving these changes. Both thinkers contributed to the foundational understanding of evolution, despite differing in their proposed mechanisms.
Lamarck proposed an erroneous evolutionary mechanism known today as?
Inheritance 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 did Lamarck propose a scientific explanation for and why?
Lamarck proposed a scientific explanation for evolution because organisms evovled through the inherititance of acquired charactaristics.
Where did Lamarck and Darwin agree on the evolution theory?
Lamarck and Darwin both agreed that species evolve over time and that this process leads to the adaptation of organisms to their environments. They recognized the importance of environmental factors in shaping traits and behaviors. However, while Lamarck proposed the inheritance of acquired characteristics as the mechanism for evolution, Darwin introduced natural selection as the primary driving force, marking a fundamental difference in their theories.
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.
What scientist had ideas about evolution and adaptation that influenced Darwin?
Jean-Baptiste Lamarck, a French biologist, proposed the idea of inheritance of acquired characteristics and the concept of transformational evolution. These ideas influenced Darwin's thinking on evolution and adaptation. However, Darwin's theory of natural selection ultimately diverged from Lamarck's ideas.
Jean Lamarck?
French naturalist who proposed that evolution resulted from the inheritance of acquired characteristics (1744-1829)
How did Lamarck's theory of evolution vary from Darwin's?
Lamarck proposed that acquired traits could be inherited, while Darwin emphasized natural selection as the mechanism for evolutionary change. Lamarck's theory focused on an organism's individual efforts to adapt, whereas Darwin's theory highlighted the role of competition and environmental factors in shaping evolution. Despite both theories contributing to our understanding of evolution, Darwin's theory has gained more support due to its emphasis on genetic variation and natural selection.
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.
Who is lamarck and what is his scientific evidence?
LAMARCK proposed the concepts of evolution called as Lamarckism.his theory consisted of two headings 1-use and dis use of organs 2-in heritance of acquired characters...
Was Lamarck correct?
Lamarck was correct about the connection between the environment and evolution. He saw that the organism changes based on the environment and its survival. However, Lamarck is not well-known for his advances in the field. Instead, he is known for the incorrect mechanisms for evolution that he proposed, including "use and disuse" and "inheritance of acquired characteristics." (A small note, Lamarck definitely did not have a "theory," he had hypotheses).
