Darwin and Huxley revisited: the origin of allometry
نویسنده
چکیده
The relative sizes of parts of an organism frequently depend on the absolute size of the individual, a relationship that is generally described by power laws. I show here that these power laws are a consequence of the way evolution operates.

Opinion Darwin and Huxley revisited: the origin of allometry
The Huxley whose name appears in the title of this article is not Thomas (Darwin’s ‘Bulldog’), but his grandson Julian, the author of Problems of Relative Growth [1], brother of the novelist Aldous (Brave New World) and half-brother of the biophysicist Andrew (the Hodgkin-Huxley equations). In 1924, Julian began studying the relative size of various organs and found many examples of what he cal...
متن کاملReading Darwin Between the Lines: A Computer- Assisted Analysis of the Concept of Evolution in The Origin of Species
Whereas Darwin is nowadays considered the founder of the modern theory of evolution, he wasn't the first to use this word in a biological context: indeed, the word "evolution" already had two distinct biological uses at the time the Origin of Species was first published (Bowler, 2003; Huxley, 1897): "initially, to refer to the particular embryological theory of preformationism; and later, to ch...

متن کاملON THEORY IN COMPARATIVE PSYCHOLOGY The fundamental theory of comparative psychology is the Darwinian theory of evolution by natural selection. Shortly after Darwin published The Origin of Species
I have endeavoured to show that no absolute structural line of demarcation, wider than that between the animals which immediately succeed us in the scale, can be drawn between the animal world and ourselves; and I may add the expression of my belief that the attempt to draw a psychical distinction is equally futile, and that even the highest faculties of feeling and intellect begin to germinate...
متن کاملAn improved pseudospectral approximation of generalized Burger-Huxley and Fitzhugh-Nagumo equations
In this research paper, an improved Chebyshev-Gauss-Lobatto pseudospectral approximation of nonlinear Burger-Huxley and Fitzhugh- Nagumo equations have been presented. The method employs chebyshev Gauss-Labatto points in time and space to obtain spectral accuracy. The mapping has introduced and transformed the initial-boundary value non-homogeneous problem to homogeneous problem. The main probl...
