Application of Phylogenetic Networks in Evolutionary Studies

by Daniel H. Huson, David Bryant - SUBMITTED TO MBE 2005 , 2005
"... The evolutionary history of a set of taxa is usually represented by a phylogenetic tree, and this model has greatly facilitated the discussion and testing of hypotheses. However, it is well known that more complex evolutionary scenarios are poorly described by such models. Further, even when evoluti ..."

Tandem repeats finder: a program to analyze DNA sequences

by Gary Benson , 1999
"... A tandem repeat in DNA is two or more contiguous, approximate copies of a pattern of nucleotides. Tandem repeats have been shown to cause human disease, may play a variety of regulatory and evolutionary roles and are important laboratory and analytic tools. Extensive knowledge about pattern size, co ..."

The Evolutionary Role of Toughness in Bargaining

by Aviad Heifetz, Ella Segev , 2003
"... The experimental evidence on the “endowment effect” (Kahneman et al. 1990) and the “self serving bias” in negotiations (Babcok and Loewenstein 1997) suggests that individuals enter a tough state of mind when they have to make a stand vis-a-vis somebody else. In this work we show how a toughness bias ..."

bias in bargaining may indeed be evolutionary viable. When the inherent toughness of the bargainer is observed by the opponent, this opponent will adjust his behavior accordingly, in a way which may enhance the actual payoff of the biased bargainer. Suppose, then, that a population consists initially

Evolutionary role of the nucleus

by Valentina Agoni
"... Communication is of great importance in cells: it is matter of survival. Cells communicate each other in many ways. Inside the cell the information proceeds through the form of signal transduction pathways. We consider a possible role of the nucleus in the regulation of the flow of information at th ..."

Simulation of Evolutionary Role of Predation

by Sambit Bikas Pal, Abhishek Dasgupta, Arghya Modak , 2007
"... In this experiment we have simulated the predator- prey relationship using a computer simulation software called NetLogo 3.1.4 and studied some aspects of prey evolution. If looked upon naively, predation seems to only have a detrimental effect on the prey popula-tion. It’s true that predation leads ..."

In this experiment we have simulated the predator- prey relationship using a computer simulation software called NetLogo 3.1.4 and studied some aspects of prey evolution. If looked upon naively, predation seems to only have a detrimental effect on the prey popula-tion. It’s true that predation leads to decline in prey population size, but predation plays an

The Simple Economics of Basic Scientific Research

by Richard R. Nelson - Journal of Political Economy , 1959
"... I begin this essay by reflecting on my early paper (Nelson, 1859), and Ken’s (Arrow, 1962), as period pieces. These papers certainly have been influential in shaping the discussion of science and technology policy over the last forty years, at least among economists, but at the time they were writte ..."
Abstract - Cited by 438 (5 self) - Add to MetaCart
recognition that technological advance must be understood as an evolutionary process, and recognition that the institutions involved in that process include much more than the simple market institutions on which economists usually focus. Then I turn to the contemporary policy arena that is the focus

Unpublished manuscript The Evolutionary Role of Art

by Kathia Castro Laszlo, Ph. D
"... This paper explores the role of art in socio-cultural evolution. The first section presents a brief overview of the development of Western art and its relation to the evolution of Western civilization. The two main perspectives on art are reviewed: functional art vs. art for art’s sake. The second s ..."

1. WHAT IS THE EVOLUTIONARY ROLE OF LANGUAGE?

by Peter Gärdenfors
"... Humans are the only animals who can deliberately plan for future needs. Our ability to have a "theory of mind" is also a factor that facilitates advanced forms of cooperation and communication. The main thesis of this article is that symbolic communication evolved in order to make cooperat ..."

The main thesis of this article is that symbolic communication evolved in order to make cooperation about future goals possible.

Functional and evolutionary roles of long repeats in prokaryotes

by Eduardo P. C. Rocha A, Antoine Danchin B, Alain Viari A
"... Abstract — Most recently published complete bacterial genomes have revealed unexpectedly high numbers of long strict repeats. In this article we discuss the various functional and evolutionary roles of these repeats, focusing in particular on their role in terms of genome stability, gene transfer, a ..."

Evolutionary role of seed oils in plants: The case of

by Jatropha Curcas L
"... Seed oils in higher plants function as an energy source for germination, emergence and establishing as a new plant. Then, the seed oil must be a trait subjected to natural selection. In this work we revise the evolutionary function of seed oils in angiosperms, analyzing the patterns of seed oil accu ..."

We review some relevant hypotheses about the evolutionary role of seed oils and their influence on plant fitness, using as case study the, apparently, inconsistent fatty acid profile of the tropical
