La evidencia genética y fósil para el origen de los humanos modernos
1Department of Palaeontology, British Museum (Natural History), London, England.
Resumen
Los orígenes del hombre moderno son debatidos. Tanto los datos genéticos como la evidencia fósil apoyan un origen africano reciente para el Homo sapiens, refutando las teorías de evolución multirregional a largo plazo.
Área de la Ciencia:
- Evolución del ser humano Evolución del ser humano
- La paleoantropología es la paleoantropología.
- Genética de la población Genética de la población.
Sus antecedentes:
- El origen del Homo sapiens es un debate científico de larga data.
- Existen dos modelos principales: la evolución multirregional y el origen africano reciente.
Objetivo del estudio:
- Para comparar el modelo de evolución multirregional con el reciente modelo de origen africano para el Homo sapiens.
- Para evaluar la evidencia de apoyo de los datos genéticos y fósiles.
Principales métodos:
- Análisis de datos genéticos de poblaciones humanas contemporáneas.
- Examen del registro fósil de homínidos de la época del Pleistoceno.
Principales resultados:
- Los datos genéticos indican una ascendencia compartida reciente para los humanos modernos.
- Los hallazgos paleontológicos se alinean con una reciente aparición de Homo sapiens.
Conclusiones:
- Tanto la evidencia genética como la fósil apoyan fuertemente un origen africano reciente para los humanos modernos.
- El modelo de evolución multirregional con flujo genético está menos respaldado por los datos actuales.

What is Evolutionary History?
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.Phylogenetic trees illustrate the evolutionary relationships among these organisms. Scientists infer organisms’ common ancestry by evaluating shared morphological and genetic characteristics. Together, the fossil...
The Evidence for Evolution
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.The collection of fossils within sedimentary rocks give a record of common ancestry and often depicts the history of evolution.
The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
Genome Size and the Evolution of New Genes
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.
Evolutionary Relationships through Genome Comparisons
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
Synteny and Evolution
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
