Who proposed that the selective use or disuse of an organ led to a change the organ that was then passed on to the offspring?
Lamarck.
How did jean baptiste de lamarck contribute to the cell theory?
Aside from Lamarck's contributions to evolutionary theory, his works on invertebrates represent a great advance over existing classifications; he was the first to separate the Crustacea, and Annelida from the "Insecta." His classification of the mollusks was far in advance of anything proposed previously; Lamarck broke with tradition in removing the tunicates and the barnacles from the . He also anticipated the work of Schleiden & Schwann in cell theory in stating that: . . . no body can have life if its constituent parts are not cellular tissue or are not formed by cellular tissue."
Who proposed that organisms acquired or lost traits during their lifetime by selective use or disuse of organs?
Jean-Baptiste Lamarck
Who was the first person to discover evolution?
Darwin and Wallace did observe evolution and believed it occured through the process of natural selection. This has been accepted by the scientific community, and was refined by molecular biology and the disovery of the mechanims behind inheritance. Gregor Mendel gave us the idea of dominant and recessive genes. However, while they are most prominently known in the history of evolutionary biology, Jean Baptiste Lamarck should be recognized for his work with evolution. It was because of Lamarck that scientists like Darwin and Wallace began to explore evolution as a plausible mechanism for the origin of the world's species. Lamarck has been largely discredited due to his proposed mechanism of evolution of inheritance as acquired characteristics which has been shown to be incorrect. However, Lamarckian theory has some validity as environment actually affects genes. This was notably shown by the study of Dutch children's genes that were affected by the fact their grandmothers or even great grandmothers had been pregnant during the horrendous famine imposed on them during the second world war.
Stated that inheritance of acquired traits caused change in a species over time?
Lamarck thought acquired traits were past on, but he was prover wrong by Darwin and his natural selection idea.
Who proposed that organisms adapt to their environment?
Lamarck.
What were the main ideas Lamarck proposed that influenced Darwin?
Lamarck proposed that traits acquired during one's lifetime could be passed to the next generation.
Which mechanism for evolution was proposed by lamarck?
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.
Who was the characteristics of inheritance proposed by?
Jean-Baptiste Lamarck
When does jean baptiste lamarcks begin classifying insects?
Beginning in 1801, Lamarck began to publish details of his evolutionary theories. Where others in the field had hinted at the possibility of evolutionary change, Lamarck declared it as being a truth and fact.
Jean-baptiste lamarck proposed that organisms have what?
he proposed the organisms pass on "acquired characteristics" such as playing the piano.
Lamarck proposed that organisms?
Lamarck proposed that organisms developed new features as a result of a 'inner urge' for improvement and that they passed on these improvements to their young/offspring. He did not accept that animals could become extinct.
What role did Jean Baptiste de Lamarck play in the development of evolutionary theory?
he didnt
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.
The French scientist Jean-Baptiste Lamarck proposed what theories?
The French scientist Jean-Baptiste Lameark proposed which of the theories?
What did jean baptiste lamarck contribute to science?
Lamarck proposed an hypothesis that had species evolving desired traits and passing them to their offspring. For example, if you were a bodybuilder, your offspring would be born with larger than normal muscles. This hypothesis, while incorrect, was still significant in the history of evolutionary thought.
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...
