TL;DR: It is suggested that differences in opinion on whether plasticity is part of the explanation for adaptive evolution or an optional “add‐on” to genes and natural selection are caused by differences in the simplifying assumptions and particular idealizations that enable evolutionary explanation.
Abstract: Developmental plasticity looks like a promising bridge between ecological and developmental perspectives on evolution. Yet, there is no consensus on whether plasticity is part of the explanation for adaptive evolution or an optional "add-on" to genes and natural selection. Here, we suggest that these differences in opinion are caused by differences in the simplifying assumptions, and particular idealizations, that enable evolutionary explanation. We outline why idealizations designed to explain evolution through natural selection prevent an understanding of the role of development, and vice versa. We show that representing plasticity as a reaction norm conforms with the idealizations of selective explanations, which can give the false impression that plasticity has no explanatory power for adaptive evolution. Finally, we use examples to illustrate why evolutionary explanations that include developmental plasticity may in fact be more satisfactory than explanations that solely refer to genes and natural selection.

TL;DR: This work systematically review research into thermal developmental plasticity across reptiles, structured around the key papers and findings that have shaped the field over the past 50 years, and introduces a large database, the 'Reptile Development Database', consisting of 9,773 trait means across 300 studies examining thermal developmental Plasticity.
Abstract: Early life environments shape phenotypic development in important ways that can lead to long-lasting effects on phenotype and fitness. In reptiles, one aspect of the early environment that impacts development is temperature (termed 'thermal developmental plasticity'). Indeed, the thermal environment during incubation is known to influence morphological, physiological, and behavioral traits, some of which have important consequences for many ecological and evolutionary processes. Despite this, few studies have attempted to synthesize and collate data from this expansive and important body of research. Here, we systematically review research into thermal developmental plasticity across reptiles, structured around the key papers and findings that have shaped the field over the past 50 years. From these papers, we introduce a large database (the 'Reptile Development Database') consisting of 9,773 trait means across 300 studies examining thermal developmental plasticity. This dataset encompasses data on a range of phenotypes, including morphological, physiological, behavioral, and performance traits along with growth rate, incubation duration, sex ratio, and survival (e.g., hatching success) across all major reptile clades. Finally, from our literature synthesis and data exploration, we identify key research themes associated with thermal developmental plasticity, important gaps in empirical research, and demonstrate how future progress can be made through targeted empirical, meta-analytic, and comparative work.

TL;DR: Non-mammalian, non-avian paradigms for studying developmental patterns of vertebrate hearts are described for several amphibians and a few reptiles, identifying, where possible, processes in common with birds and mammals.
Abstract: Although most research on developmental cardiovascular physiology has focused on the bird embryo as a model for emulating developmental processes in mammals, there are increasingly compelling reasons to expand research to a variety of lower vertebrate systems. These reasons include circumventing inherent limitations of the avian embryo and identifying general vertebrate developmental patterns in the cardiovascular system. In this paper, we first review data from hemodynamic studies on amphibians and birds (and what little exists from fish and reptiles), to provide a background against which lower vertebrate development can be examined. We then describe non-mammalian, non-avian paradigms for studying developmental patterns of vertebrate hearts. Developmental spects of cardiovascular performance, especially heart rate, blood pressure and cardiac output and how they change with ontogeny, are described for several amphibians and a few reptiles, identifying, where possible, processes in common with birds and mammals. Finally, we indicate productive areas for future research with lower vertebrate cardiovascular systems, such as establishing "critical windows" for cardiovascular physiology during development, and determining the extent of developmental plasticity at the level of organ system physiology.
