The '''Archean Eon''', also spelled '''Archaean''', is a geologic eon that extends from about 4.0 to 2.5 billion years ago (4.0 to 2.5 Ga). It follows the [[Hadean Eon]] and precedes the [[Proterozoic Eon]] in the geologic time scale. The Archean is notable for the formation of the Earth's [[crust]] and the emergence of life, particularly in the form of [[prokaryotes]].

==Overview==
'''Antonia Coello Novello''' (born August 23, 1944) is a Puerto Rican physician and public health administrator. She was the first woman and the first Hispanic to serve as [[Surgeon General of the United States]], holding the position from 1990 to 1993. Her tenure was marked by a focus on the health of women, children, and minorities, as well as efforts to combat [[AIDS]] and [[tobacco]] use.
During the Archean, the Earth's crust cooled enough to allow the formation of [[continent]]s and oceans. This period saw the first stable [[continental crust]] formations, known as [[cratons]]. These ancient cratons are the core of modern continents. The atmosphere and oceans were forming, though the atmosphere lacked [[oxygen]] and was primarily composed of [[carbon dioxide]], [[nitrogen]], and [[water vapor]].


==Geology==
==Early Life and Education==
The geology of the Archean is characterized by the widespread occurrence of greenstone belts, high-grade [[metamorphic rocks]], and [[granite]]s. Greenstone belts are zones of variably metamorphosed mafic to ultramafic volcanic sequences with associated sedimentary rocks that are found in the Archean cratons. These belts are important for understanding the early Earth's crustal evolution and are major sources of [[gold]] and other minerals.
Antonia Novello was born in [[Fajardo, Puerto Rico]]. She faced significant health challenges from a young age, suffering from a congenital condition that required multiple surgeries. Despite these challenges, she excelled academically and pursued a career in medicine. Novello earned her [[Doctor of Medicine|M.D.]] degree from the [[University of Puerto Rico School of Medicine]] in 1970. She later completed a [[Master of Public Health|Master of Public Health]] degree from the [[Johns Hopkins School of Hygiene and Public Health]].


==Life==
==Career==
The Archean Eon is significant for the origin of life. The oldest known [[fossils]] of life forms date back to around 3.5 billion years ago. These early life forms were [[microorganisms]], primarily [[prokaryotes]], which are organisms without a nucleus. The emergence of [[photosynthesis]] during the Archean, particularly among [[cyanobacteria]], began to increase the level of oxygen in the atmosphere, setting the stage for the evolution of aerobic (oxygen-breathing) life forms in later eons.


==Subdivisions==
===Medical Practice===
The Archean Eon is divided into four principal [[geologic era|eras]]: the [[Eoarchean]], [[Paleoarchean]], [[Mesoarchean]], and [[Neoarchean]]. These eras are defined based on significant geological and biological events, as well as [[isotopic dating]] and [[stratigraphy]].
Novello began her medical career as a pediatrician, focusing on nephrology. Her work in this field led her to the [[National Institutes of Health]] (NIH), where she conducted research and worked on health policy.


==Significance==
===Public Health Service===
The Archean Eon is crucial for understanding the early development of the Earth and the origins of life. Studies of Archean rocks provide insights into the conditions of the early Earth and the processes that led to the formation of its continents, oceans, and atmosphere. The emergence of life during the Archean marks one of the most significant evolutionary milestones in Earth's history.
In 1978, Novello joined the [[United States Public Health Service Commissioned Corps]], where she held various positions, including Deputy Director of the National Institute of Child Health and Human Development. Her work at the NIH and her advocacy for children's health brought her to the attention of policymakers.
