Darwin and Lamarck had fundamentally different views on how species change over time. Lamarck proposed that organisms could acquire traits during their lifetime and pass those traits to their offspring, a process known as inheritance of acquired characteristics. In contrast, Darwin introduced the theory of natural selection, suggesting that individuals with advantageous traits are more likely to survive and reproduce, leading to gradual changes in species over generations. Thus, while Lamarck emphasized individual effort and adaptation, Darwin focused on environmental pressures and genetic variation.

How did lamarck's theory affect Darwin's thinking?
Lamarck's theory of inheritance of acquired characteristics influenced Darwin by introducing the idea that organisms could change over time in response to their environment. Although Darwin ultimately rejected Lamarck's mechanisms, he was inspired by the concept of adaptation and the idea that species are not fixed. This led him to explore natural selection as a more robust explanation for how species evolve and adapt. Thus, while Darwin diverged from Lamarckism, he acknowledged its role in shaping his thoughts on evolution.
What are some similarities in Lamarck and Darwin. Theory?
Both Lamarck and Darwin contributed significantly to the understanding of evolution, emphasizing the adaptation of species to their environments. They recognized that organisms change over time, although their mechanisms differed: Lamarck proposed the inheritance of acquired characteristics, while Darwin introduced natural selection as the primary driver of evolution. Both theories acknowledge the importance of environmental influences on species, highlighting a shared interest in how life evolves. Ultimately, while their explanations diverged, they both sought to explain the diversity of life on Earth.
How did Darwin and Lamarck differ in their thinking about change in species?
Darwin and Lamarck had fundamentally different views on how species change over time. Lamarck proposed that organisms could acquire traits during their lifetime and pass those traits to their offspring, a process known as inheritance of acquired characteristics. In contrast, Darwin introduced the theory of natural selection, suggesting that species evolve through the differential survival and reproduction of individuals based on heritable traits that confer advantages in a given environment. This marked a significant shift toward understanding evolution as a gradual process driven by natural mechanisms rather than intentional adaptations.
Who theorized that organisms evolve by passing on advantageous traits to their offspring?
Lamarck did. Neodarwinism theorises that species evolve when gene frequencies change, not individual organisms. Larmarkism is true for epigenetic inheritance, favourable and unfavourable characteristics alike.
In what ways did Lamarck and Darwin agree?
Lamarck and Darwin both agreed on the idea that organisms change over time and that these changes can lead to the evolution of new species. They recognized the influence of the environment on the traits of organisms, suggesting that adaptations can arise in response to environmental pressures. Additionally, both scientists acknowledged the importance of variation within species, although they differed significantly in their explanations of how these changes occur.

What are the same between Darwin and lamarck?
That they were both transformationists, a word the meant in those days one thought organisms evolved over time, and thought species arose by natural processes. The mechanisms proposed by them varied a great deal though.
Why is lamarck and Darwin's theory so important?
Both Lamarck's theory of inheritance of acquired traits and Darwin's theory of evolution by natural selection were important because they laid the foundation for understanding how species change over time. Lamarck proposed that organisms could acquire traits during their lifetime and pass them on to their offspring, while Darwin's theory explained how species adapt to their environment through a process of natural selection. These theories revolutionized the field of biology and continue to influence our understanding of the diversity of life on Earth.

How did the ideas of scientists before Darwin influence Darwin ideas?
Scientists before Darwin, such as Lamarck and Lyell, influenced Darwin's ideas by presenting concepts like geology and the idea of species change over time. Lamarck's theory of acquired characteristics and Lyell's principles of uniformitarianism provided a basis for Darwin to develop his theory of evolution through natural selection. Darwin built upon these ideas by incorporating them into his own theory, which became the foundation of modern evolutionary biology.
Who Described evolution by natural selection?
Charles Darwin is credited with this theory in his book, The Origin Of Species. ---> Actually... Jean-Baptiste Pierre Antoine de Monet, Chevalier de la Marck (AKA Lamarck) was the first to propose the hypothesis that species change over time.
How did Lamarck propose that species change over time?
Lamarck proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. Then passed onto offspring-leading to change in species
What ideas related to evolution did lamarck and Charles Darwin share?
The basic one of evolution. That organisms change over time.
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.
