1.5 The Microbial Family Tree Flashcards
Who was Carl von Linné?
He was a Swedish botanist and famous classifer of species. He called the microbe world “chaos”.
Who disapproved of categorizing microbes with either plants or animals?
Ernst Haeckel, he recognized that microbes differed from both plants and animals in fundamental aspects of their lifestyle, cellular structure, and biochemistry.
Who created Monera?
Ernst Haeckel, he said it was a way to categorize microbes as a third important category of life.
Why was classifying microbes a challenge?
Because of difficulties in observing distinguishing characteristics of different categories.
Who classified prokaryotes as a form of microbial life distinct from eukaryotic microbes such as protists?
Herbert Copeland and Robert Whittaker
Who was Lynn Margulis?
Proposed that eukaryotic organelles such as the mitochondria and chloroplasts evolved by endosymbiosis from prokaryotic cells engulfed by pre-eukaryotes.
Who was Carl Woese?
Discovered a domain of prokaryotes, Archaea, whose genetic sequences diverge equally from those of bacteria and eukaryotes. Archaea grow in a wide range of environments; some species grow under conditions that exclude bacteria and eukaryotes.
