  2. Archean life in the Barberton Greenstone Belt - Wikipedia

    en.wikipedia.org/wiki/Archean_life_in_the...

    Scientists have established the approximate age that life first appears in the fossil record, but this is not equivalent to the age that life first evolved on Earth. Though fossils have not been found in older rocks, evidence for life can be found in other ways, such as extended carbon isotope data and Raman Spectroscopy. There is also ongoing ...

  4. Eukaryogenesis - Wikipedia

    en.wikipedia.org/wiki/Eukaryogenesis

    Eukaryogenesis, the process which created the eukaryotic cell and lineage, is a milestone in the evolution of life, since eukaryotes include all complex cells and almost all multicellular organisms. The process is widely agreed to have involved symbiogenesis , in which an archeon and a bacterium came together to create the first eukaryotic ...

  5. Timeline of the evolutionary history of life - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_the...

    In biology, evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organization , from kingdoms to species , and individual organisms and molecules , such as DNA and proteins .

  6. Evolution of cells - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_cells

    Evolution of cells refers to the evolutionary origin and subsequent evolutionary development of cells. Cells first emerged at least 3.8 billion years ago [ 1 ] [ 2 ] [ 3 ] approximately 750 million years after Earth was formed.

  7. Evidence of common descent - Wikipedia

    en.wikipedia.org/wiki/Evidence_of_common_descent

    The history of the camel provides an example of how fossil evidence can be used to reconstruct migration and subsequent evolution. The fossil record indicates that the evolution of camelids started in North America (see figure 4e), from which, six million years ago, they migrated across the Bering Strait into Asia and then to Africa, and 3.5 ...

  8. Protists in the fossil record - Wikipedia

    en.wikipedia.org/wiki/Protists_in_the_fossil_record

    A protist is any eukaryotic organism (that is, an organism whose cells contain a cell nucleus) that is not an animal, plant, or fungus.While it is likely that protists share a common ancestor, the last eukaryotic common ancestor, [1] the exclusion of other eukaryotes means that protists do not form a natural group, or clade.

  9. Molecular paleontology - Wikipedia

    en.wikipedia.org/wiki/Molecular_paleontology

    mid-1950s: Abelson found preserved amino acids in fossil shells that were about 360 million years old. Produced idea of comparing fossil amino acid sequences with existing organism so that molecular evolution could be studied. [12] 1970s: Fossil peptides are studied by amino acid analysis. [14] Start to use whole peptides and immunological ...
