Resumen
Los clados marinos como los amonoides y los braquiópodos se recuperaron de la extinción masiva del Pérmico-Triásico mediante el rellenado del morfoespacio. Los ostrácodos, sin embargo, ampliaron sus nichos ecológicos y su diversidad a través de la radiación adaptativa.
Sus antecedentes:
- La acumulación de biodiversidad a lo largo de millones de años se ve salpicada por eventos de extinción masiva.
- Comprender cómo los linajes supervivientes reconstruyen la diversidad después de una extinción es crucial para los estudios evolutivos.
Conclusiones:
- La rápida diversificación morfológica puede impulsar la expansión ecológica y la diversidad taxonómica sostenida.
- La PTME remodeló fundamentalmente los ecosistemas marinos al inducir caminos de recuperación variados entre los supervivientes.
- Diferentes clados exhibieron estrategias distintas para reconstruir la biodiversidad después de un evento de extinción importante.

02:56The Fossil Record
27.0K
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?
42.9K
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.

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

01:33Whole Body Regeneration
4.0K
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential;...
