Resumen
Los fósiles de monos del Nuevo Mundo (platirrinos) descubiertos en Panamá revelan la diversificación temprana de los primates en los trópicos. Este hallazgo proporciona la evidencia fósil más antigua de intercambio de mamíferos entre América del Sur y América del Norte.
Área de la Ciencia:
- Paleontología
- Biología evolutiva
- La evolución de los primates
Sus antecedentes:
- Los monos del Nuevo Mundo (platirrinos) son parte integral de los ecosistemas neotrópicos, pero su historia evolutiva temprana sigue siendo poco conocida.
- Los datos moleculares sugieren que los primates se dispersaron en América Central desde América del Sur después de que se formara el istmo de Panamá hace 3-4 millones de años (Ma).
- La falta de fósiles de primates en América Central ha dificultado la comprensión de sus orígenes en el Nuevo Mundo.

02:56The Fossil Record
28.3K
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...

02:35What is Evolutionary History?
44.6K
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.

01:54Convergent Evolution
34.3K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

02:31Synteny and Evolution
4.0K
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.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

01:23Phylogeny
64.4K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
