“…In this section, we aim to re-evaluate the hypothesis that the CLIP (and interpreted preserved plume conduits) formed above the Galápagos hotspot by testing six different plate motion configurations using the GPlates software (Müller et al, 2018). We used the recently published regional plate kinematic models of Boschman et al (2014) and Montes et al (2019a), for which the rotation files are available, and three different absolute reference frames, i.e. the "subduction reference model" of Van Der (Campbell, 2005) and 2500 km (Mauffret et al, 2001).…”

Abstract. Remnants of the Caribbean Large Igneous Plateau (CLIP) are found as thicker than normal oceanic crust in the Caribbean Sea, that formed during rapid pulses of magmatic activity at ~ 91–88 Ma and ~ 76 Ma. Strong geochemical evidence supports the hypothesis that the CLIP formed due to melting of the plume head of the Galápagos hotspot, which interacted with the Farallon (Proto-Caribbean) plate in the east Pacific. Considering the plate tectonics theory, it is expected that the lithospheric portion of the plume-related material migrated within the Proto-Caribbean plate, in a north–north-eastward direction, developing the present-day Caribbean plate. In this research, we used 3D lithospheric-scale, data-integrative models of the current Caribbean plate setting to reveal, for the first time, the presence of positive density anomalies in the uppermost lithospheric mantle. These models are based on the integration of up-to-date geophysical datasets, from the Earth’s surface down to 200 km depth, which are validated using high-resolution free-air gravity measurements. Based on the gravity residuals (modelled minus observed gravity), we derive density heterogeneities both in the crystalline crust and the uppermost oceanic mantle (

“…The present-day Caribbean plate is composed of different accreted crustal domains (e.g. volcanic arcs, continental and oceanic realms) which have migrated since Late Jurassic to Early Cretaceous times, including the igneous plateau materials that affected the oceanic crust of the former Farallon plate (Boschman et al, 2014;Montes et al, 2019a).…”

“…Arrival of oceanic-borne terranes to the Cretaceous passive margin of northwestern South America took place during one or several arc-continent collisions (see review in Montes et al, 2019). Collisions built relief along the margin of northwestern South America (see review in Bayona, 2018), shedding coarse-grained clastic material, sand and gravel, marking the start of a regional marine regression and the establishment of swampy conditions where shallow marine conditions had been prevalent for a long time.…”

“…From this time onwards (latest Cretaceous to the south, to middle Paleocene in the north) we can define a primordial, probably discontinuous, Central Cordillera from Guayaquil to the Guajira peninsula. This orogen may have taken ~10 million years to propagate from south to north (see review in Montes et al, 2019). This range would have spawned the first Amazonian/Orinoco-style drainages, shutting down most or all westward-directed drainages of the region (Hoorn et al, 2010).…”

AimTo evaluate the potential role of the orogeny of the Eastern Cordillera (EC) of the Colombian Andes and the Mérida Andes (MA) of Venezuela as drivers of vicariance between populations of 37 tetrapod lineages co-distributed on both flanks, through geological reconstruction and comparative phylogeographic analyses.LocationNorthwestern South AmericaMethodsWe first reviewed and synthesized published geological data on the timing of uplift for the EC-MA. We then combined newly generated mitochondrial DNA sequence data with published datasets to create a comparative phylogeographic dataset for 37 independent tetrapod lineages. We reconstructed time-calibrated molecular phylogenies for each lineage under Bayesian inference to estimate divergence times between lineages located East and West of the Andes. We performed a comparative phylogeographic analysis of all lineages within each class of tetrapod using hierarchical approximate Bayesian computation (hABC) to test for synchronous vicariance across the EC-MA. To evaluate the potential role of life history in explaining variation in divergence times among lineages, we evaluated 13 general linear models (GLM) containing up to six variables each (maximum elevation, range size, body length, thermoregulation, type of dispersal, and taxonomic class).ResultsOur synthesis of geological evidence suggested that the EC-MA reached significant heights by 38–33 million years ago (Ma) along most of its length, and we reject the oft-cited date of 2–5 Ma. Based on mtDNA divergence from 37 lineages, however, the median estimated divergence time across the EC-MA was 3.26 Ma (SE = 2.84) in amphibians, 2.58 Ma (SE = 1.81) in birds, 2.99 Ma (SE = 4.68) in reptiles and 1.43 Ma (SE = 1.23) in mammals. Using Bayes Factors, the hypothesis for a single temporal divergence interval containing synchronous divergence events was supported for mammals and but not supported for amphibians, non-avian reptiles, or birds. Among the six life-history variables tested, only thermoregulation successfully explained variation in divergence times (minimum AICc, R2 0.10), with homeotherms showing more recent divergence relative to poikilotherms.Main conclusionsOur results reject the hypothesis of the rise Andean Cordillera as driver of vicariance of lowland population because divergence dates are too recent and too asynchronous. We discuss alternative explanations, including dispersal through mountain passes, and suggest that changes in the climatic conditions during the Pliocene and Pleistocene interacted with tetrapod physiology, promoting older divergences in amphibians and reptiles relative to mammals and birds on an already established orogen.

Botany and geogenomics: Constraining geological hypotheses in the neotropics with large‐scale genetic data derived from plants

Decades of empirical research have revealed how the geological history of our planet shaped plant evolution by establishing well‐known patterns (e.g., how mountain uplift resulted in high rates of diversification and replicate radiations in montane plant taxa). This follows a traditional approach where botanical data are interpreted in light of geological events. In this synthesis, I instead describe how by integrating natural history, phylogenetics, and population genetics, botanical research can be applied alongside geology and paleontology to inform our understanding of past geological and climatic processes. This conceptual shift aligns with the goals of the emerging field of geogenomics. In the neotropics, plant geogenomics is a powerful tool for the reciprocal exploration of two long standing questions in biology and geology: how the dynamic landscape of the region came to be and how it shaped the evolution of the richest flora. Current challenges that are specific to analytical approaches for plant geogenomics are discussed. I describe the scale at which various geological questions can be addressed from biological data and what makes some groups of plants excellent model systems for geogenomics research. Although plant geogenomics is discussed with reference to the neotropics, the recommendations given here for approaches to plant geogenomics can and should be expanded to exploring long‐standing questions on how the earth evolved with the use of plant DNA.
