In biological nomenclature, organisms often receive scientific names that honor a person. A taxon (e.g., species or genus; plural: taxa) named in honor of another entity is an eponymous taxon, and names specifically honoring a person or persons are known as patronyms.
This list is part of the List of organisms named after famous people, and includes organisms named after famous individuals born before 1 January 1800. It also includes ensembles in which at least one member was born before that date; but excludes companies, institutions, ethnic groups or nationalities , and populated places.
This list is part of the List of organisms named after famous people, and includes organisms named after famous individuals born between 1 January 1800 and 31 December 1899.

For example, this was probably important for carbon fixation. [ a ] Carbon fixation by reaction of CO 2 with H 2 S via iron-sulfur chemistry is favorable, and occurs at neutral pH and 100 °C. Iron-sulfur surfaces, which are abundant near hydrothermal vents, can drive the production of small amounts of amino acids and other biomolecules.
The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence , mainly fossils .
Proterospongia (members of the Choanoflagellata) are the best living examples of what the ancestor of all animals may have looked like. They live in colonies, and show a primitive level of cellular specialization for different tasks.
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage. For the earlier history of the human lineage, see Timeline of human evolution#Hominidae, Hominidae#Phylogeny.
