Abstract Historical-narrative evolutionary explanations for the origin and further evolution of avian feathers involve two steps. The first phase reconstructs a series of probable morphological changes from a reptilian scale to the primitive feather. The second deduces possible functions and biological roles of the features and feasible selective demands on these features at all stages in its evolution. The best explanation for the evolutionary origin of feathers would be one consistent with… 
The early evolution of feathers: fossil evidence from Cretaceous amber of France
Fossil evidence of an intermediate and critical stage in the incremental evolution of feathers which has been predicted by developmental theories but hitherto undocumented by evidence from both the recent and the fossil records is reported.
Religion and Its Cultural Evolutionary By-products
A cultural evolutionary perspective on one of the most prevalent kind of lay beliefs: Religion, and more specifically the belief in Big Gods: powerful, watchful, morally concerned deities, and by-products that these beliefs have that are separate from their initial adaptive function of promoting cooperation.

Foam Nests Provide Context-Dependent Thermal Insulation to Embryos of Three Leptodactylid Frogs
The data indicate that foam nests insulate embryos from daily temperature fluctuations among leptodactylid frogs with different degrees of terrestrial nests, which may well have contributed to the evolution of this reproductive strategy.
More Complex Complexity: Exploring the Nature of Computational Irreducibility across Physical, Biological, and Human Social Systems
It is suggested that the computational irreducibility of biological and social systems is distinguished from physical systems by functional contingency, biological evolution, and individual variation.
Explanations in evolutionary theory
All phyletic evolutionary change, no matter how extensive it may be, never crosses species taxa boundaries; hence it is not possible to distinguish ‘trans-specific evolution’ (= evolution beyond or above the level of the species) from evolution within the species level.
Horse hooves and bird feathers: Two model systems for studying the structure and development of highly adapted integumentary accessory organs--the role of the dermo-epidermal interface for the micro-architecture of complex epidermal structures.
The structure and development of feathers in birds are compared to those of the hoof capsule in horses, and the equine hoof is the most complex mammalian integumentary structure, which is determined directly by the dermal surface of the papillary body.


The Evolutionary Origin of Feathers

The development of feathers is complex and a model is proposed that gives attention to the fundamental problems of deriving a branched structure with a cylindrical base from an elongated scale.
The origin and evolution of birds
Ornithologist and evolutionary biologist Alan Feduccia, author of "Age of Birds," here draws on fossil evidence and studies of the structure and biochemistry of living birds to present knowledge and data on avian evolution and propose a model of this evolutionary process.
The Evolution of Feathers *
The hypothesis is put foward that feathers evolved due to selection for a water‐repellent integument because a porous surface repels water drops more strongly than does a solid surface of the same material.
Functional Microanatomy of the Feather-Bearing Integument: Implications for the Evolution of Birds and Avian Flight1
Evidence is presented for the fact that the ancestral birds were probably small, arboreal, hopping, and using flap-bounding, or intermittent bounding, flight and the critical role that a streamlined body plays in avian flight is likely to have played in the evolutionary transformations.
Aerodynamic Model for the Early Evolution of Feathers Provided by Propithecus (Primates, Lemuridae)
The lemurs known as sifakas provide a crucial, yet to date overlooked, analogy that illustrates parsimoniously how feathers could have evolved directly from brachial scales as aerodynamic features, with each successive minor evolutionary stage fully adaptive.
The wing of Archaeopteryx as a primary thrust generator
The calculations provide a solution to the ‘velocity gap’ problem and shed light on how a running Archaeopteryx (or its cursorial maniraptoriform ancestors) could have achieved the velocity necessary to become airborne by flapping feathered wings.
Functional and Evolutionary Explanations in Morphology
What is needed in morphology is the proper blend of functional and historical evolutionary explanations to arrive at persuasive full explanations, and a true evolutionary morphology will emerge with great advances in derived phylogenetic and classificatory analyses.

The model suggested for the sequence of events in the origin of new groups is an evolutionary change that involves a series of many steps, each representing an intermediate stage between the ancestral and descendent groups; occurs in an intermediate adaptive zone; and involves a number of phyletic lines.
Feathers of Archaeopteryx: Asymmetric Vanes Indicate Aerodynamic Function
Vanes in the primary flight feathers of Archaeopteryx conform to the asymmetric pattern in modern flying birds, suggesting that they evolved in the selective context of flight.
