“…Co-evolutionary interactions related to specialized feeding, the related ''evolutionary arms race'' that accelerated in the late Mesozoic and Cenozoic (4,5,40), and, perhaps, increasing nutritional contributions to the oceans from diversifying flowering plants (6) may combine to explain the continuing post-Paleozoic increase in taxonomic richness. New community types may also reflect the evolution of increased specialization, further contributing to increase in diversity (4,6,17,26).…”

We grouped the fossil records of marine animal genera into suites defined by function and physiology. The stratigraphic coherence of the resulting diversity history indicates the importance of ecological structure in constraining taxonomic richness through time. The proportional representation of major functional groups was stably maintained for intervals as long as 200 million years, despite evolutionary turnover and changes in total diversity. Early Paleozoic radiations established stable ecosystem relationships, and thereafter only the great era-bounding mass extinctions were able to break patterns of incumbency, permitting the emergence of new community structures with distinct proportional diversity relationships.

The evolution of Earth's biota is intimately linked to the oxygenation of the oceans and atmosphere. We use the isotopic composition and concentration of molybdenum (Mo) in sedimentary rocks to explore this relationship. Our results indicate two episodes of global ocean oxygenation. The first coincides with the emergence of the Ediacaran fauna, including large, motile bilaterian animals, ca. 550-560 million year ago (Ma), reinforcing previous geochemical indications that Earth surface oxygenation facilitated this radiation. The second, perhaps larger, oxygenation took place around 400 Ma, well after the initial rise of animals and, therefore, suggesting that early metazoans evolved in a relatively low oxygen environment. This later oxygenation correlates with the diversification of vascular plants, which likely contributed to increased oxygenation through the enhanced burial of organic carbon in sediments. It also correlates with a pronounced radiation of large predatory fish, animals with high oxygen demand. We thereby couple the redox history of the atmosphere and oceans to major events in animal evolution.T he concentration of O 2 in the Earth's atmosphere and oceans has increased over time from negligible levels early in Earth history to the 21% we have in the atmosphere today (1-3). Our understanding of this history is indirect, based mainly on a series of geochemical proxies reflecting chemical interactions between O 2 and other oxidation-reduction (redox) sensitive elements. These proxies include the isotopic compositions and concentrations of elements such as S, Fe, and Mo preserved in sedimentary rocks (3-7). Several of these proxies (4,5,8,9) indicate an increase in oceanic O 2 during the Ediacaran Period (635 to 542 million years ago, Ma), roughly synchronous with the emergence of large, motile bilaterian animals and, therefore, suggestive of a physiological link between Ediacaran evolution and environmental change. Despite this, the distribution of organic-rich shales (10, 11), the ratio of pyrite sulfur to organic carbon in shales (12), and modeling of the sulfur isotope record (13,14) all indicate that large tracts of subsurface ocean remained anoxic well into the early Phanerozoic Eon (the "age of visible animals," since 542 million years ago). Levels of ocean and atmospheric oxygenation, however, are unquantified from these proxies. Indeed, the most comprehensive history of Phanerozoic oxygenation has been inferred from biogeochemical models. These models diverge, however, on their predictions for the Paleozoic, suggesting either low (15) or high levels of atmospheric oxygen (16,17). Here, we present an independent record of ocean oxygenation history derived from the isotopic composition and concentration of Mo in black shales.The geochemical behavior of Mo is controlled by the relative availability of dissolved H 2 S and O 2 in the oceans. In oxic waters, Mo is soluble and exists as the molybdate anion, MoO 4 2− . In sulfidic waters, molybdate reacts with H 2 S to form particlereactive oxythiomo...

“…La percepción histórica de las plantas como el grupo dominante en la tierra, junto con los primeros descubrimientos de fósiles macroscópicos sólo en rocas Fanerozoicas y la incapacidad para interpretar correctamente biofirmas microbianas, tal vez han contribuido a la comprensión generalizada de los 'ecosistemas terrestres' exclusivamente para las plantas (i.e. Bambach, 1999). En algunos casos, incluso cuando la existencia de ecosistemas terrestres Precámbricos es reconocida, éstos se tratan dudosamente (Shear, 1991;DiMichele y Hook, 1992;Gray y Shear, 1992;Gray y Boucot, 1994;Bambach, 1999;Blackwell, 2000;Corcoran y Mueller, 2004;Nesbitt y Young, 2004;Gensel, 2008) a pesar de previas e importantes discusiones al respecto (i.e.…”

La vida temprana en la Tierra y los primeros ecosistemas terrestres 65 ResumenLos ecosistemas terrestres han sido considerados tradicionalmente como superficies dominadas por plantas, cuyos primeros registros datan del Fanerozoico temprano (< 550 Ma/millones de años). Sin embargo, la presencia de componentes biológicos mucho más antiguos que las plantas en hábitats tan distintos como suelos, turberas, estanques, lagos, arroyos y dunas, sugiere que los ecosistemas terrestres comenzaron a existir en la Tierra hace al menos 2700 Ma. Los microbios fueron abundantes hace ~3500 Ma y sin duda se adaptaron a vivir en condiciones subaéreas, en entornos intermareales y en zonas áridas y semiáridas, como lo hacen actualmente los microbios terrestres, y que tienen una enorme y rápida capacidad de adaptación a condiciones cambiantes. Todo ello está respaldado por el registro fósil. No obstante, esta evidencia es inusual e indirecta en comparación con fósiles de ambientes marinos, superficiales o profundos, y su registro ha sido poco atendido. En consecuencia, la noción de que fueron comunidades microbianas las que formaron los primeros ecosistemas terrestres no ha sido ampliamente difundido ni incorporado conceptualmente en la sociedad. Hoy conocemos un amplio registro fósil de biota marina somera y lacustre a partir de los ~3500 Ma, así como microbios colonizando ambientes costeros desde hace ~3450 Ma y evidencia indirecta de actividad biológica en paleosuelos de > 3400 Ma de edad. El tipo de ambientes, de donde proviene esta evidencia, sugiere que la vida terrestre se produjo casi en paralelo con la vida acuática en el Arqueano. Las rápidas adaptaciones observadas en microbios actuales, su excepcional tolerancia a condiciones extremas y fluctuantes, su rápida y temprana diversificación y su antiguo registro fósil, indican que los primeros ecosistemas terrestres fueron exclusivamente microbianos. Es factible que los microbios contribuyeran en la formación de los primeros suelos donde las plantas se desarrollaron más tarde. Comprender cómo la vida se diversificó y adaptó a las condiciones terrestres es fundamental para entender su impacto en los sistemas terrestres durante millones de años. Beraldi-Campesi 66 661. Introducción Definición de terrestreLos ambientes terrestres seguramente han existido a través de toda la historia geológica de la Tierra a menos que su superficie estuviera permanentemente bajo el agua, lo cual no es aceptablemente realista. La definición de 'terrestre' no es tan trivial como parece. Aunque aquí se define como un ambiente 'no acuático', la distinción entre lo marino y lo terrestre atraviesa un amplio espectro de ambientes transicionales, donde lo acuático y lo no-acuático evolucionan y superponen en el tiempo. Comúnmente se entiende que un entorno terrestre (sobre el nivel del mar), puede incluir ambientes acuáticos (lagos cubiertos o no de hielo, lagunas y humedales, turberas, ríos y arroyos, campos geotérmicos) y no-acuáticos (especialmente zonas con poca lluvia). Estos hábitats pueden experimen...
