The male-only nest care system of some birds may have its evolutionary origins in theropod dinosaur behavior. 

Topics from this paper

Sexual Dimorphism of Parental Care: From Genes to Behavior.
TLDR
It is suggested that a more comprehensive understanding of the underlying mechanisms can be achieved by expanding the methodological toolbox, applying ethologically relevant approaches such as nontraditional wild-derived animal models and complex seminatural experimental set-ups. Expand
Mixed paternity despite high male parental care in great tinamous and other Palaeognathes
TLDR
Paternity assurance is not required for male parental care to be maintained, because males can increase their reproductive success by mating with multiple females, by siring offspring in other males' nests and by reducing predation risk to their offspring in larger clutches. Expand
THE LANDE–KIRKPATRICK MECHANISM IS THE NULL MODEL OF EVOLUTION BY INTERSEXUAL SELECTION: IMPLICATIONS FOR MEANING, HONESTY, AND DESIGN IN INTERSEXUAL SIGNALS

  • 2010
The Fisher‐inspired, arbitrary intersexual selection models of Lande (1981) and Kirkpatrick (1982) , including both stable and unstable equilibrium conditions, provide the appropriate null model forExpand
Flying ticks: anciently evolved associations that constitute a risk of infectious disease spread
TLDR
The study of host-tick-pathogen associations reveals a prominent role for birds in the dissemination of Borrelia spp. Expand
Evolutionary Specialization of the Tongue in Vertebrates: Structure and Function
TLDR
This review summarizes and discusses many specializations of tongue form and function among tetrapods, finding that the tongue has become almost vestigial in a few species of anurans, turtles, and birds. Expand
Sociology/WS 327A: Sex and Gender in Society
Sociology 327A is an overview of sex and gender from the perspective of social constructionism. This means that we will look at how people create and sustain the categories that they use to makeExpand
Modeling Dad: Animal models of paternal behavior
TLDR
This work highlights the possibility that paternal behavior has components that are strictly masculine with unique neurobiological mechanisms, and provides a current view of a topic that needs further exploration. Expand
The Father on Display: The House of Jean Monnet and the Construction of European Identity
In the 1980s, the EC engaged in trying actively to construct a European identity, primarily through a ‘manufacturing of symbols', such as a common flag, hymn and day of celebration. A lesser-knownExpand
Queering Street: Homosociality, Masculinity, and Disability in Friday Night Lights
Gender and ability are integral to the cultural significance of sport, but contemporary media depictions of high school athletes rarely direct attention to the interaction of these issues. InExpand
Anti-Anxiety Law: Winnicott and the Legal Fiction of Paternity
Winnicott's good-enough mother does not, on the face of it, seem to have anything to do with the process of fact-finding in law. Yet there is an uncanny similarity between Winnicott's theory of theExpand

Avian Paternal Care Had Dinosaur Origin
TLDR
Paternal care in both troodontids and oviraptorids indicates that this care system evolved before the emergence of birds and represents birds' ancestral condition. Expand
A Pair of Shelled Eggs Inside A Female Dinosaur
TLDR
The orientations of the eggs inside the skeleton and in clutches indicate that the mother came to the center of the nest to lay eggs, suggesting that an entire egg clutch was laid through multiple ovipositions. Expand
Four-winged dinosaurs from China
TLDR
New evidence is provided suggesting that basal dromaeosaurid dinosaurs were four-winged animals and probably could glide, representing an intermediate stage towards the active, flapping-flight stage of proavians. Expand
A nesting dinosaur
TLDR
The specimen described here is the first preserved well enough to determine its precise relationship with the nest, and provides the strongest evidence yet for the presence of avian brooding behaviour in non-avian dinosaurs. Expand
On the Origin of Parental Care and the Early Evolution of Male and Female Parental Roles in Birds
TLDR
It is proposed that biparental care originated then, when parental care was already obligatory and environmental conditions demanded the constant presence of a parent, and the system of care prevailing among living birds was changed. Expand
Gender-Specific Reproductive Tissue in Ratites and Tyrannosaurus rex
TLDR
The presence of endosteally derived bone tissues lining the interior marrow cavities of portions of Tyrannosaurus rex hindlimb elements are reported, and it is hypothesized that these tissues are homologous to specialized avian tissues known as medullary bone. Expand
Nest and egg clutches of the dinosaur Troodon formosus and the evolution of avian reproductive traits
TLDR
Non-avian coelurosaurians possess several primitive features found in crocodilians and several derived features shared with birds (relatively larger and potentially asymmetric eggs, one egg produced per oviduct at a time, loss of egg retention, open nests, brooding). Expand
WHY ORNITHOLOGISTS SHOULD CARE ABOUT THE THEROPOD ORIGIN OF BIRDS
TLDR
G. Heilmann (1926) concluded that birds had evolved from ‘‘thecodonts’’—a polyphyletic garbage bag assemblage of early archosaurs, and his hypothesis was the basis of many scenarios. Expand
The Evolution of Avian Breeding Systems
TLDR
This is the first book to combine the themes of sexual selection, parental care, and mating systems, and to focus exclusively on birds, and will be welcomed by researchers in animal behaviour and ornithology with an interest in mating systems. Expand
The origin of parental care in birds: a reassessment
TLDR
A multistage model of the origin of parental care and the evolution of parental roles in birds was proposed, which assumed that powered flight evolved for reasons independent of reproduction, and that parental care evolved as a response to it, within a framework of limitations set by adaptations to aerial locomotion.
