An analysis of the fallacy of the cattle complex theory and its implications on the development of t

Understanding the niche concept is central to explaining the evolution of complex ecological communities. The niche encompasses several dimensions of a population's existence that affect its contribution to the total flow of resources through a community see Levins ; Vandermeerincluding: A population's niche may be divided into its fundamental niche and its realized niche see Vandermeer

The ecophenotypic factor of size makes no distinctions as each polygon becomes elongated along this second axis, and as the truly larger fossil shells from Aruba occupy a separate position at the high size end of this spectrum.

Kinsella writes of a midwestern farmer so beguiled by the legend of the great baseball hero Shoeless Joe Jackson that he constructs a stadium in his wheatfield because he heard a voice saying to him: The basic diagram Fig.

As discussed in my previous analysis of Darwin's brilliant argument in Chapter 6 of the Origin pp. At the functional vertex, natural selection stands alone as the only known and effective cause in this mode.

But inheritance does not so operate, on this planet at least. But so long as these All vertices may yield aptive traits of great utility to the organism. Finally, at the structural vertex, Darwin allowed that features not arising for functional reasons, but only coopted for current utility, must be admitted as genuine exceptions to the principle that adaptive features can only originate for functional reasons with natural selection as the only known and sufficiently powerful functional mechanism.

Finally, at the structural vertex, one would have to counter Darwin's argument by asserting that he greatly underestimated the relative frequencies of these admitted exceptions to natural selection for the origin of currently functional features — a claim that I will advance in Chapter I shall begin with the simple and more direct question posed from the structural vertex: I shall consider these two structural categories seriatim, and in depth, in Chapter 11, and will therefore only present the basic conceptual framework here.

Pure D'Arcy Thompsonians maintain little interest in history and phylogeny, and may even become overtly hostile to the commanding influence of these concepts in evolutionary biology.

At any time, any lineage located in this domain must behave in the same way. This version of structuralism embraces the classical spatiotemporal invariance of natural law, and cares little if at all about historical pathways that happen to potentiate the law's operation in any particular case.

Spandrelists, in strong contrast, generally share the evolutionary biologist's traditional fascination for contingent details of history in individual lineages under study.

Spandrels do express general and predictable properties, but they originate as necessary consequences of particular triggers that can only be understood in a historical and phylogenetic context. If Julia Pastrana grew two rows of teeth as a correlated consequence of her abnormal hairiness see p.

The structural vertex poses a direct question about the origin of currently adaptive features themselves: The historical vertex, on the other hand, poses a more indirect challenge that might better be designated as a metaquestion: I shall argue that two prominent discoveries have magnified the importance of historical constraints vs.

Second, the importance of parallelism a concept rooted in internal constraint for explaining independently evolved features of distant phyla; traits long touted as textbook examples of convergence a concept rooted in externally conditioned adaptation.

Both themes, however, have forced evolutionary biologists to reassess the importance of constraints at the historical vertex for explaining the actual distribution of adaptive form within potential organic morphospace.

Just as I argued previously that no actual empirical case would fall precisely at a vertex of total determination by one factor alone, I also acknowledge that no subtle thinker's theory will fall right on a vertex either. In this case Fig.

What we label as primary causes and what we consider as constraints follow from the logic of our preferred theory. Under strictly functional views of natural selection, the functional vertex represents the orthodox cause of current action by natural selection, whereas the historical vertex imposes constraints based on past adaptations and the structural vertex imposes architectural constraints based on limitation in the nature of building materials.

For a structuralist thinker like D'Arcy Thompson, optimal forms built directly by physical laws become canonical, and influences from other vertices become constraints — either of ecological particulars from the functional vertex, or of contingency from the historical vertex.

For a cladist interested in historical reconstruction of branching sequences, the historical vertex becomes primary, and influences from the other two vertices represent constraints — ahistorical constraints of universal physics from the structural vertex and autapomorphies of particular and immediate adaptation from the functional vertex.
