LIFE SCIENCE

Detailed explanation-1: -The Prokaryote/Eukaryote nomenclature had been proposed by Chatton in 1937 to classify living organisms into two major groups: prokaryotes (bacteria) and eukaryotes (organisms with nucleated cells). Adopted by Stanier and van Neil this classification was universally accepted by biologists until recently (21).

Detailed explanation-2: -The eukaryotes developed at least 2.7 billion years ago, following some 1 to 1.5 billion years of prokaryotic evolution. Studies of their DNA sequences indicate that the archaebacteria and eubacteria are as different from each other as either is from present-day eukaryotes.

Detailed explanation-3: -Édouard Chatton (French: [edwaʁ ʃatɔ̃]; 11 October 1883 – 23 April 1947) was a French biologist who first characterized the distinction between the prokaryotic and eukaryotic cellular types.
