No. He died in 1930 and it wasn't until the sixties that the theory was accepted by the mainstream scientific community.
No
The atomic theory of Democritus was not widely accepted during his lifetime. The dominant Greek philosopher of the era, Aristotle, opposed all ideas concerning atomic theory, refusing to believe that anything such as an atom could even exist.
No, not until later was this theory proven and supplemented by the theory of plate tectonics.
Sea floor spreading was not known during Wegener's lifetime because the technology to map the ocean floor, such as sonar mapping, did not exist yet. Without this technology, scientists were unable to detect the mid-ocean ridges where sea floor spreading takes place. Additionally, Wegener's theory of continental drift was met with skepticism and not widely accepted during his time, which may have deterred further exploration into related concepts like sea floor spreading.
He certainly was.
Alfred Wegener first proposed the theory of continental drift in 1912, in which he suggested that the continents had once been joined together in a supercontinent called Pangaea. While his ideas were not widely accepted during his lifetime, they later formed the basis for the theory of plate tectonics.
Jean-Baptiste Lamarck was the scientist who proposed the theory of acquired characteristics, suggesting organisms could acquire or lose traits during their lifetime through the use or disuse of certain organs. This theory was later replaced by Darwin's theory of evolution by natural selection.
The term for this theory is Lamarckism, named after the French biologist Jean-Baptiste Lamarck. According to Lamarckism, traits acquired during an individual's lifetime can be inherited by their offspring. This concept has been largely discounted in modern biology in favor of the theory of inheritance through genetic material.
The cell theory became an accepted part of biology in the 19th century. Rudolf Virchow, Matthias Schleiden, and Theodor Schwann are credited with contributing to the development and acceptance of the cell theory during this time period.
Ideologically for the most part. More research needs to be done about his actual contributions during his lifetime, but widely accepted timelines have him as an old man when during the war.
French biologist Jean-Baptiste Lamarck believed in the equilibrium of nature. His theory of evolution suggests that traits acquired by organism during its lifetime will be passed on to the offspring.
Yes, Peter was in Rome during his lifetime.
