Serial Homology

چکیده

Abstract Serial homology, i.e., homology between repetitive structures in the same individual organism, is a debated concept evolutionary developmental biology. The central question interpretation of “sameness” context body. This essay provides synthetic analysis main issues involved debate, connecting conceptual problems with current experimental research. It argued that serial not all-or-nothing kind can smooth several theoretical inconsistencies, while being more line what we know about change and way investigate it.

Serial homology: the crests and cusps of mammalian teeth

I discuss the nature of serial homology. Mammalian teeth have a relatively dense fossil record, which permits an often close reconstruction of the evolution of patterns of serial homology. I identify the main crests of mammalian teeth, summarize their evolution, and provide new names where necessary. Serial homologies can change in evolution, originate, and disappear. They can be partial, unlik...

Serial Correlation Coefficient

In this paper, we investigate the relation between two variables where the one is measured with the ratio or interval scale and the other with the nominal. In this cases, we use from serial correlation coefficient. Computation of some serial coefficient such as biserial and point-biserial coefficient is carried out with some examples and R program.

The origins of adipose fins: an analysis of homoplasy and the serial homology of vertebrate appendages.

Adipose fins are appendages found on the dorsal midline between the dorsal and caudal fins in more than 6000 living species of teleost fishes. It has been consistently argued that adipose fins evolved once and have been lost repeatedly across teleosts owing to limited function. Here, we demonstrate that adipose fins originated repeatedly by using phylogenetic and anatomical evidence. This sugge...

Genetic and developmental bases of serial homology in vertebrate limb evolution

The last decade has witnessed a dramatic revival of interest in understanding the connection between developmental process and morphological change during evolution (Raff, 1996; Gerhart and Kirschner, 1997). Much insight has been gained by comparing the expression patterns and functions of homologous developmental genes among different taxa (Akam, 1995; Carroll, 1995). These surveys emphasize t...
