Lamarck Posited the concept of acquired characteristics being heritable and the organisms " need " to adapt physiological parts, such as giraffes " needing " longer necks. Needless to say both of these main concepts of Lamarck's were wrong.
Darwin posited the theory of evolution by natural selection that saw selected variations of organisms evolving over time by their progeny inheriting favorable characteristics. Darwin had the evidence that Lamarck did not and his theory, with modifications, is still the best explanation of evolution and the origin of species extant.
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.
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.
Lamarck and Darwin had differing theories on how species evolve. Lamarck proposed that organisms evolve through the inheritance of acquired characteristics, suggesting that traits gained during an organism's lifetime can be passed to offspring (e.g., giraffes stretching their necks). In contrast, Darwin introduced the theory of natural selection, which posits that individuals with advantageous traits are more likely to survive and reproduce, passing those traits to future generations. While Lamarck emphasized adaptive changes within a lifetime, Darwin's theory focused on gradual changes over generations driven by environmental pressures.
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.
Darwin, of course. Lamarck did not have the evidence to back up his acquired characteristics and use and disuse concepts, but Darwin had massive amounts of evidence and well structured arguments for his theory of natural selection.
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.
Do Lamarck's theories provide a good explanation for the change in months? Why or why not?

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.
Darwin read the book Lamarck wrote and said that he did not get one idea from it as it was ludicrous in content. So, Lamarck would be the one scientist that did not influence Darwin according to Darwin.
Some scientists and researchers who influenced Charles Darwin include Thomas Malthus, Jean-Baptiste Lamarck, and John Gould. Malthus's theories on population dynamics and resources helped shape Darwin's ideas on natural selection. Lamarck's proposal of the inheritance of acquired traits also impacted Darwin's thinking. John Gould's work on the Galapagos finches provided Darwin with important evidence for his theory of evolution.

They both propose that organisms are not immutable, but changes over time. However the mechanisms of the two theories are very different.
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.
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.
