Sensory and Cognitive Adaptations to Social Living in Insect Societies Tom Wenseleersa,1 and Jelle S
COMMENTARY COMMENTARY Sensory and cognitive adaptations to social living in insect societies Tom Wenseleersa,1 and Jelle S. van Zwedena A key question in evolutionary biology is to explain the solitarily or form small annual colonies, depending upon causes and consequences of the so-called “major their environment (9). And one species, Lasioglossum transitions in evolution,” which resulted in the pro- marginatum, is even known to form large perennial euso- gressive evolution of cells, organisms, and animal so- cial colonies of over 400 workers (9). By comparing data cieties (1–3). Several studies, for example, have now from over 30 Halictine bees with contrasting levels of aimed to determine which suite of adaptive changes sociality, Wittwer et al.

In this context, a long-standing hypothesis is that ery linked to chemical communication, as measured by the evolution of the spectacular sociality seen in in- the density of their antennal sensillae, compared with sects, such as ants, bees, or wasps, should have gone species that secondarily reverted back to a solitary life- hand in hand with the evolution of more complex style.

This finding suggests that the increased reliance signals mainly in the context of mate attraction and on chemical communication that comes with a social species-recognition, social insects use chemical sig- lifestyle indeed selects for fast, matching adaptations in nals in a wide variety of contexts: to communicate their sensory systems. -

Samantha Kee RS 299-Writing With Public Purpose Dr. Brian Stiltner March 2, 2012 Following the trail of ants An examination of the work of E.O. Wilson Edward Osborne Wilson was a born naturalist, in every sense of the word. As a child growing up in Alabama, he collected and studied species of snakes, flies, and the insect that became the basis of his life’s work, ants. He made a goal to record every species of ant that could be found in Alabama—a childhood project that would eventually lead to his first scientific publication. By age 13, Wilson discovered a red, non-native ant in a local town in Alabama, and by the time he entered the University of Alabama, the fire ant had become a significant threat to the state’s agriculture. -
A Memetic Framework for Cooperative Coevolution of Recurrent Neural Networks

Biol B242 - Coevolution
BIOL B242 - COEVOLUTION http://www.ucl.ac.uk/~ucbhdjm/courses/b242/Coevol/Coevol.html BIOL B242 - COEVOLUTION So far ... In this course we have mainly discussed evolution within species, and evolution leading to speciation. Evolution by natural selection is caused by the interaction of populations/species with their environments. Today ... However, the environment of a species is always partly biotic. This brings up the possiblity that the "environment" itself may be evolving. Two or more species may in fact coevolve. And coevolution gives rise to some of the most interesting phenomena in nature. What is coevolution? At its most basic, coevolution is defined as evolution in two or more evolutionary entities brought about by reciprocal selective effects between the entities. The term was invented by Paul Ehrlich and Peter Raven in 1964 in a famous article: "Butterflies and plants: a study in coevolution", in which they showed how genera and families of butterflies depended for food on particular phylogenetic groupings of plants. We have already discussed some coevolutionary phenomena: For example, sex and recombination may have evolved because of a coevolutionary arms race between organisms and their parasites; the rate of evolution, and the likelihood of producing resistance to infection (in the hosts) and virulence (in the parasites) is enhanced by sex. We have also discussed sexual selection as a coevolutionary phenomenon between female choice and male secondary sexual traits. In this case, the coevolution is within a single species, but it is a kind of coevolution nonetheless. One of our problem sets involved frequency dependent selection between two types of players in an evolutionary "game". -

Part 2 Raghavendra Gadagkar Continuing to explore the fascinating world of the Indian pa- per wasp Ropalidia marginata, in this article, we will ask how wasps choose their queens in another context. In the previ- ous article in this series, we saw how a simple experiment re- vealed that wasps fight, i.e., indulge in dominance-subordinate interactions, and the winner becomes the queen and the loser becomes the worker. This was in the context of new nestfoundation. But contextmatters.

The Coevolution Theory of Autumn Colours Marco Archetti1* and Sam P
Received 3 December 2003 FirstCite Accepted 25 February 2004 e-publishing Published online The coevolution theory of autumn colours Marco Archetti1* and Sam P. Brown2 1De´partement de Biologie, Section E´ cologie et E´ volution, Universite´ de Fribourg, Chemin du Muse´e 10, 1700 Fribourg, Switzerland 2Department of Zoology, University of Cambridge, Downing Street, Cambridge CB2 3EJ, UK According to the coevolution theory of autumn colours, the bright colours of leaves in autumn are a warning signal to insects that lay their eggs on the trees in that season. If the colour is linked to the level of defensive commitment of the tree and the insects learn to avoid bright colours, this may lead to a coevolutionary process in which bright trees reduce their parasite load and choosy insects locate the most profitable hosts for the winter. We try to clarify what the theory actually says and to correct some misun- derstandings that have been put forward. We also review current research on autumn colours and discuss what needs to be done to test the theory. Keywords: autumn colours; coevolution; biological signalling; trees; evolution 1.

The Last Universal Common Ancestor (LUCA) has been normally considered as the ancestor of cellular organisms that originated the three domains of life: Bacteria, Archaea and Eukarya. Recent studies about the nature of LUCA indicate that this first organism should present hundreds of genes and a complex metabolism. Trying to bring another of Darwin ideas into the origins of life discussion, we went back into the prebiotic chemistry trying to understand how LUCA could be originated 1 © 2018 by the author(s).
