Evolutionary legacies structure the geography of seagrass traits across the world's oceans
New Phytologist, EarlyView.Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.

, 2013 What determines the transition of a society from one level of development to another? One of the most fundamental causes is the global technological trans-formations. Among all major technological breakthroughs in history the most important are the three production revolutions: 1) the Agrarian Revolution; 2) the Industrial Revolution and 3) the ...

Macroevolution of arboreality in salamanders [PDF]
Ecology and Evolution, 2019 AbstractEvolutionary theory predicts that selection in distinct microhabitats generates correlations between morphological and ecological traits, and may increase both phenotypic and taxonomic diversity. However, some microhabitats exert unique selective pressures that act as a restraining force on macroevolutionary patterns of diversification. In this

The Scientific World Journal, 2006 In this paper, we first give a short discussion of the macroevolution viewing life as information-directed, complex, dynamic systems. On this basis, we give our explanation of the origin of life and discuss the top-down evolution of molecules, proteins ...

The Macroevolutionary Consequences of Niche Construction in Microbial Metabolism
Frontiers in Microbiology, 2021 Microorganisms display a stunning metabolic diversity. Understanding the origin of this diversity requires understanding how macroevolutionary processes such as innovation and diversification play out in the microbial world.

Ecological change may be a common initiator of evolutionary pollinator shifts
New Phytologist, EarlyView.Summary Although evolutionary pollinator shifts are accepted as major sources of floral and species diversity in angiosperms, the mechanisms triggering pollinator shifts remain largely unexplored. In 1970, Stebbins proposed that ecological change may be a common initiator of evolutionary pollinator shifts, but empirical tests of Stebbins' hypothesis ...

Tempo and Mode of the Evolution of Venom and Poison in Tetrapods
Toxins, 2016 Toxic weaponry in the form of venom and poison has evolved in most groups of animals, including all four major lineages of tetrapods. Moreover, the evolution of such traits has been linked to several key aspects of the biology of toxic animals including ...

SiPhyNetwork: An R package for simulating phylogenetic networks
Methods in Ecology and Evolution, 2023 Gene flow is increasingly recognized as an important macroevolutionary process. The many mechanisms that contribute to gene flow (e.g. introgression, hybridization, lateral gene transfer) uniquely affect the diversification of dynamics of species, making

The Cambrian Explosion: macroevolution and biomineralization
Academia Biology, 2023 Recent advances in our understanding of the Cambrian evolutionary diversification event (Cambrian Explosion) show that, although eumetazoan stem taxa were present in the late Proterozoic, a tremendous burst of macroevolutionary change occurred near the ...

Journal of Anatomy, Volume 248, Issue 5, Page 806-829, May 2026.In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable
