Agassiz found that his palaeontological analyses required a new ichthyological classification. The fossils that he examined rarely showed any traces of the soft tissues of fish but instead, consisted chiefly of the teeth, scales, and fins, with the bones being perfectly preserved in comparatively-few instances. He therefore adopted a classification that divided fish into four groups (ganoids, placoids, cycloids, and ctenoids), based on the nature of the scales and other dermal appendages. That did much to improve fish

In his later years, Agassiz applied his glacial theories to the geology of the Brazilian tropics, including the Amazon. Agassiz began with a working hypothesis which could be tested by the results of fieldwork to find either inconclusive, or conclusively supporting or refuting evidence. A hypothesis that can be conclusively refuted is better than a hypothesis that difficult to test. Agassiz had a close association with his student and field assistant, the geologist
Charles Hartt who eventually refuted Agassiz's theories about the Amazon based on his fieldwork there. Instead of evidence for any glacial processes, he found chemically weathered sediments from marine and tropical fluvial, not glacial, processes, a finding that later geologists confirmed. Agassiz hypothesis that the Amazon was affected by the

Legacy
The Cambridge elementary school north of Harvard University was named in his honor, and the surrounding neighborhood became known as "
Agassiz" as a result. The school's name was changed to the Maria L. Baldwin School on May 21, 2002, because of concerns about Agassiz's involvement in scientific racism and to honor
Maria Louise Baldwin, the African-American principal of the school, who served from 1889 to 1922.
The neighborhood, however, continued to be known as Agassiz. Circa 2009, neighborhood residents decided to rename the neighborhood's community council as the "Agassiz-Baldwin Community". Then, in July 2021, culminating a two-year effort on the part of neighborhood residents, the Cambridge City Council voted unanimously to change the name to the Baldwin Neighborhood.

Daguerreotypes of Renty and Delia Taylor
In 1850, Agassiz commissioned daguerreotypes
Daguerreotype (; french: daguerréotype) was the first publicly available photographic process; it was widely used during the 1840s and 1850s. "Daguerreotype" also refers to an image created through this process.
Invented by Louis Daguerre an ...
, which were described as "haunting and voyeuristic" of the enslaved Renty Taylor and Taylor's daughter, Delia, to further his arguments about black inferiority. They are the earliest known photographs of enslaved persons. Agassiz left the images to Harvard, and they remained in the Peabody Museum's attic until 1976, when they were rediscovered by Ellie Reichlin, a former staff member. The 15 daguerrotypes were in a case with the embossing "J. T. Zealy, Photographer, Columbia," with several handwritten labels, which helped in later identification. Reichlin spent months doing research to try to identify the people in the photos, but Harvard University did not make efforts to contact the families and licensed the photos for use.
In 2011, Tamara Lanier wrote a letter to the president of Harvard that identified herself as a direct descendant of the Taylors and asked the university to turn over the photos to her.
In 2019, Taylor's descendants sued Harvard for the return of the images and unspecified damages. The lawsuit was supported by 43 living descendants of Agassiz, who wrote in a letter of support, "For Harvard to give the daguerreotypes to Ms. Lanier and her family would begin to make amends for its use of the photos as exhibits for the white supremacist theory Agassiz espoused." Everyone must evaluate fully "his role in promoting a pseudoscientific justification for white supremacy."
Polygenism and racism
After Agassiz came to the United States, he wrote prolifically in the field of scientific polygenism. His purpose was to develop better working hypotheses so a complete theory could explain his and his colleagues collective observations of the natural world. He was a superior scientist in his era, and the outstanding natural scientist of his generation in the North America. Distinguished Professor of English Christoph Irmscher called him the "Creator of American Science".
After scientific colleagues explained their findings, he became an early proponent of the Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent.
Ice sheets covered much of Northern North America, Northern Eur ...

, and the lack of "missing link" fossil evidence in his era, it seemed to him and many others that the evidence indicated that there had been multiple creation events separated by worldwide and/or regional catyclysms, rather than a single creation event.
He did not consider Darwin's Theory of Evolution to have sufficient evidence when it was first presented in 1859. In fact, he had also identified the wide variety of speciation during his own earlier field work. He well knew the earth was much older than some Bible readers assumed. He rejected the Lamarckian idea of inheritance of acquired characteristics
Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime. It is also calle ...
that Darwin had accepted and later expanded upon in his writings on heredity.
Agassiz asserted that the evidence being presented by his contemporaries was not sufficient to conclude that migration

.
Lurie (1954) mentions that Agassiz developed (what in retrospect is considered) a co-Adamist hypothesis to explain the distribution of life forms, which holds that animals, plants, and humans were all created in "special provinces" with distinct populations of species created in and for each province, and that these populations were endowed with different attributes. A more exacting explanation is that Agassiz succinctly described what was obvious around the world: Various regions have differentiated species of plants and animals, and mankind appeared to be speciated also. "Special provinces" means "uniquely speciated zones" or in Agassiz own words: "natural zoological provinces".[Types of Mankind: Or, Ethnological Researches Based Upon the Ancient Monuments, Paintings, Sculptures, and Crania of Races, and Upon Their Natural, Geographical, Philological and Biblical History : Illustrated by Selections from the Inedited Papers of Samuel George Morton and by Additional Contributions from L.

He considered this hypothesis testable, and matched to the available evidence. He also indicated that there were obvious geographical barriers that were the likely cause of speciation. His observation and thoughts were presented at a time when it was important to carefully explain why a single creation event was unlikely. The available fossil record showed major gaps rather than a continuum of species through the ages because researchers had not discovered locations that contained the "missing link" fossils. So Agassiz and others focused on Variation, which contributed to the Modern Synthesis
Modern synthesis or modern evolutionary synthesis refers to several perspectives on evolutionary biology, namely:

would not be developed until over a century in the future.
According to Agassiz, as presented by the anthropologist Josiah Clark Nott

. Agassiz believed that one species of humans exists, but many different creations of races occurred.[Paul M. Blowers, 2008, "Entering 'This Sublime and Blessed Amphitheatre': Contemplation of Nature and Interpretation of the Bible in the Patristic Period, ''In'' "Nature and Scripture in the Abrahamic Religions: Up to 1700", 2 vols (Scott Mandelbrote & Jitse van der Meer, Eds.), , book , pp. 147–176, esp. 159–164 and 151–154, chapter , accessed June 8, 2014.] According to Agassiz, genera and species were ideas in the mind of God; their existence in God's mind prior to their physical creation meant that God could create humans as one species, yet in several distinct and geographically separate acts of creation. Agassiz was in modern terms a creationist
Creationism is the religious belief that nature, and aspects such as the universe, Earth, life, and humans, originated with supernatural acts of divine creation. Gunn 2004, p. 9, "The ''Concise Oxford Dictionary'' says that creationism is 'th ...

asserted that Agassiz's observations sprang from racist bias, in particular from his revulsion on first encountering African-Americans in the United States. Referencing letters written by Agassiz, Gould compares Agassiz' public display of dispassionate objectivity to his private correspondence, in which he describes "the production half breeds" as "a sin against nature..." Describing the interbreeding of white and black people, he warns, "We have already had to struggle, in our progress, against the influence of universal equality... but how shall we eradicate the stigma of a lower race when its blood has once been allowed to flow freely into our children." In contrast, others have asserted that, despite favoring polygenism, Agassiz rejected racism and believed in a spiritualized human unity. However, in the same article, Agassiz asks the reader to consider the hierarchy of races, mentioning "The indomitable, courageous, proud Indian, — in how very different a light he stands by the side of the submissive, obsequious, imitative negro, or by the side of the tricky, cunning, and cowardly Mongolian! Are not these facts indications that the different races do not rank upon one level in nature
Agassiz never supported slavery

and claimed his views on polygenism had nothing to do with politics. His views on polygenism have been claimed to have emboldened proponents of slavery.
Accusations of racism against Agassiz have prompted the renaming of landmarks, schoolhouses, and other institutions (which abound in Massachusetts) that bear his name. Opinions about those moves are often mixed, given his extensive scientific legacy in other areas, and uncertainty about his actual racial beliefs. In 2007, the Swiss government

Following Darwin's elucidation of evolutionary theory in 1859, which in its early years had inconsistencies, Agassiz sponsored expeditions and motivated others to continue to advance natural history in the direction the evidence promoted. He had a great deal of respect for scientists who did actual field work to discover new evidence, even for scientists such as Darwin and his Darwinist colleagues at Harvard. Finding evidence to corroborate or refute a hypothesis could be arduous and life-threatening.
