The initial version of a classification system of life by British zoologist Thomas Cavalier-Smith appeared in 1978. [1] [2] This initial system continued to be modified in subsequent versions that were published until he died in 2021.
The last of the non-avian dinosaurs died 66 million years ago in the course of the Cretaceous–Paleogene extinction event, whereas the earliest members of the genus Homo (humans) evolved between 2.3 and 2.4 million years ago. This places a 63-million-year expanse of time between the last non-avian dinosaurs and the earliest humans.
A small number of scientists include a sixth kingdom, Archaea, but do not accept the domain method. [68] Thomas Cavalier-Smith, who published extensively on the classification of protists, in 2002 [71] proposed that the Neomura, the clade that groups together the Archaea and Eucarya, would have evolved from Bacteria, more precisely from ...
Bergey's Manual Trust was established in 1936 to sustain the publication of Bergey's Manual of Determinative Bacteriology and supplementary reference works. The Trust also recognizes individuals who have made outstanding contributions to bacterial taxonomy by presentation of the Bergey Award and Bergey Medal, jointly supported by funds from the Trust and from Springer, the publishers of the ...

The Vienna Dioscurides manuscript of De Materia Medica, from the early sixth century, is one of the oldest herbals in existence. Dioscorides wrote the book between 50 and 60 AD. The history of plant systematics—the biological classification of plants—stretches from the work of ancient Greek to modern evolutionary biologists. As a field of ...
