	Throw Another Thrip On The Barbie
		Thrips are a tiny insect which show fascinating levels of social behaviour, says Dr David Morris, who joined CSIRO Entomology this week as a new postdoctoral fellow in the Australian National Insect Collection (ANIC).
		The new appointment at CSIRO Entomology promises to reveal insights into the evolution of social behaviour, through the study of thrips.
		Thrips are also one of the few insect groups to have developed social behaviours.

	Social Insects Point To Non-genetic Origins Of Societies; Social Structures Form Through Group Dynamics, Not Trait Selection
		Though insect social systems are in many ways as complex as human societies, Fewell contends that the relative simplicity of the insects themselves argues against the systems being created solely by the evolutionary development of biocomplexity in the individual organisms.
		Male Susceptibility To Disease May Play Role In Evolution Of Insect Societies (May 24, 2004) -- A pair of scientists has proposed a new model for behavioral development among social insects, suggesting that a higher male susceptibility to disease has helped shape the evolution of the...
		The ability of certain animals to form complex social systems -- particularly humans and social insects like bees, ants and termites-- is considered by many biologists to be one of the pinnacles of biological adaptation and complexity.

	Lecture Outline
		75% of all insect biomass consists of social insects (termites, ants, bees, and social wasps)
		Evolution of sociality in termites is thought to be different from that in social Hymenoptera, possibly through feeding communities for exchanging cellulose digesting symbionts and intense sibling competition (group selection)
		Note that conditions favoring evolution of sociality may not be the same as those important in maintaining sociality

		Ito, Y. A new epoch in joint studies of social evolution: molecular and behavioural ecology of aphid soldiers.
		not every individual reproduces equally in the group, in most cases of insects, this means there is one or a few reproductive(s) ("queen", or "king"), and workers are more or less sterile.
		Further, Hamilton argued that haplodiploidy must have played an important role in the evolution of sociality because it occurred 11 times in Hymenoptera, but much fewer times in other organisms combined.

		Convergent evolution describes the situation when animals that are distantly related - like the robber crab and an insect- can evolve similar adaptations in response to natural selection.
		A land crab re-invented key features of the insect nose over millions of years - a striking example of convergent evolution, Current Biology reports.
		Insects evolved some 438-408 million years ago, from an ancestor that also crawled out of water into an air-filled terrestrial environment.

		Insects range in length from the feathery-winged dwarf beetle, which is barely visible to the naked eye at 0.25 mm (0.01 in), to the walkingstick of Southeast Asia, which measures up to 50 cm (20 in) with its legs stretched out.
		Insect exoskeletons are highly effective as a body framework, but they have two drawbacks: they cannot grow once they have formed, and like a suit of armor, they become too heavy to move when they reach a certain size.

	Gordon's Social Wasps Page
		Polistes represents a relatively simple life cycle which is well adapted to a temperate climate, whereas Polybiine wasps show not only greater numbers and diversity but a greater degree of evolutionary flexibility which has allowed them to colonise a wider range of habitats and to be among the foremost of eusocial insects.
		Perennial species never produce so many sexuals that they can dominate the workers, and this along with a lengthened lifespan of the queens may be important steps in the evolution of the more advanced eusocial species.
		These pages are here free for you to use, I would like to keep them that way, however making and running this site, and the other sites I am currently making or have made, on Birds, Mammals, Insects and Fish and Bacteria as well as all the other invertebrates costs money.

	Convergent Evolution - EvoWiki
		If cetaceans derived from land animals, as evolution claims, then it is no surprise that they would move their tails up and down, and therefore that their tail flukes would be horizontal.
		Their diet, ants and termites, are another example of convergent evolution.
		Bird wings have a characteristic architecture, one that differs from the characteristic architecture of bat wings, and likewise for pterosaur and insect wings.

		Evolution of Communication and Language: Consider an evolving population of neurally controlled artificial animals (animats), each capable of sending out simple signals.
		What neural architectures can support the evolution of more complex signalling systems -- ones involving syntactic/semantic features of human languages, such as constituent structure, negation, reference to events removed in time and space, indexicals, and so on.

	Origins of Viruses
		An interesting "emerging virus" is tomato spotted wilt virus - genus Tospovirus, family Bunyaviridae - which is postulated to have relatively recently acquired the ability to infect plants as well as its thrips vector insect, as well as obtaining a movement function, and is now a major pathogen of a wide range of plant species.
		The new science (or art) of virus molecular systematics is, however, shedding a great deal of light on the distant relationships of, and in some cases on the presumed origins of, many important groups of viruses.
		For example, leafhopper A virus and Rhopalosiphum padi [aphid] virus are both stable enough and are injected into plants at sufficient concentration by their hosts, to make the plants into "circulative non-propagative" vectors of the viruses.

		One of the substantial contributions of Social Evolution in Ants is its clear explanation of kin selection theory and sex ratio theory and their applications to social evolution in insects.
		Biologists since Darwin have been intrigued and confounded by the complex issues involved in the evolution and ecology of the social behavior of insects.
		This comprehensive, up-to-date, and well-referenced work will appeal to all researchers in social insect biology and to scholars and students in the fields of entomology, behavioral ecology, and evolution.

		Despite interesting discussions of reaction norms (Wcislo) and a genetic model of social evolution in haplodiploid taxa (Saito), none of the work reviewed identifies specific genetic changes underlying social transitions (e.g., Ross and Shoemaker, 1997).

	Schmid-Hempel, P.: Parasites in Social Insects.
		Current ideas are evaluated using a broad database, and the role of parasites for the evolution and maintenance of the social organization and biology of insects is carefully scrutinized.
		In addition, the author develops new insights, especially in his examination of the intricate relationships between parasites and their social hosts through the rigorous use of evolutionary and ecological concepts.
		Schmid-Hempel identifies gaps in our knowledge about parasites in social insects and uses models to develop new questions for future research.

	Social insects pull together
		have manipulated the key ecological genetic and social factors predicted to influence the evolution of 'reproductive skew', which is the sharing of reproduction in groups of multiple breeders.
		The data do not support an alternative explanation, that in a 'social contract', dominant individuals are favoured to concede some reproduction to subordinates to retain their help.
		A number of theories have been put forward to explain how such societies might evolve by natural selection, but this is a field where experimental data are hard to come by.

	Insect Societies
		Note that in none of the social insects are the sterile workers and/or soldiers genetically identical, nor do the castes differ systematically in their genetic composition.
		The integrated division of labor within the insect colony (with the various castes of workers and soldiers) has been achieved by selection of single queens.
