Phylogeny

Understanding a phylogeny is a lot like reading a family tree. ❋ Unknown (2009)

Professor Haeckel in his Generelle Morphologie and in other works, has recently brought his great knowledge and abilities to bear on what he calls phylogeny, or the lines of descent of all organic beings. ❋ Unknown (2006)

Professor Haeckel in his “Generelle Morphologie” and in another works, has recently brought his great knowledge and abilities to bear on what he calls phylogeny, or the lines of descent of all organic beings. ❋ Unknown (2005)

Mr. Darwin says, "Professor Haeckel, in his general Morphology and other works, has brought his great knowledge and abilities to bear on what he calls phylogeny or the lines of descent of all organic beings." ❋ Various (N/A)

Professor Häckel in his ‘Generelle Morphologie, ’ and in other works, has recently brought his great knowledge and abilities to bear on what he calls phylogeny, or the lines of descent of all organic beings. ❋ Unknown (1909)

A phylogeny is a nested hierarchy of descendant relationships and is closely allied to taxonomy. ❋ Unknown (2009)

Even though it pains me to disagree, and especially because of fine gentleman like Allen MacNeill, I do not view evolutionary theory (as in phylogeny and natural selection) as science. ❋ Unknown (2008)

If this new phylogeny is valid (I should note by the way that Wake was on the authorship of Mueller et al., so it's not as if this study disagrees with his own research), it means that we have to re-assess the evolution of the different life history strategies seen in plethodontids. ❋ Darren Naish (2006)

Incidentally, exactly how microbiotheriids fit into marsupial phylogeny is a hotly debated topic that would require a post all its own. ❋ Darren Naish (2006)

In any case, similar arguments have been made for over a hundred years (see the eye, the feature, major transitions in phylogeny, the complement system, etc.) ❋ Unknown (2006)

From the outset I therefore believed that the mechanisms of memory storage were likely to be conserved in phylogeny, and that a cellular analysis of learning in a simple animal would reveal universal mechanisms that are also employed in more complex organisms. ❋ Unknown (2001)

Thus, distinguishing the mechanisms involved in community assembly requires knowing the evolutionary history of a group of species, which is represented by a special type of graph called a phylogeny, essentially a family tree of the species (Fig. 1). ❋ Unknown (2009)

What, however, may be said is that the difficulties presented by what is called phylogeny -- that is, the relationships of different classes to one another -- are so great as to have led more than one man of science to proclaim his belief that evolution has been poly -- and not mono -- phyletic. ❋ Bertram Coghill Alan Windle (1893)

Ochrophytes, despite being home for kelps and diatoms and such, do not qualify, apparently -- their phylogeny is a mess, many of their groups completely understudied, and ... yeah, my little amoeba exercise kind of failed miserably as I fell deeper and deeper into confusion. ❋ Psi Wavefunction, Skeptic Wonder (2010)

Frederick Cohan-the Origins of Ecological Diversity in Prokaryotes Paul Sereno - Dinosaurs: Phylogenetic reconstruction from Darwin to the present Peter & Rosemary Grant-Natural Selection, Speciation, and Darwin's Finches A phylogeny is a statement about the evolutionary history of organisms. ❋ Unknown (2009)

Haeckel mean by his new term "phylogeny," which ought to cover the lines of descent in all organic beings? ❋ R. W. Wright (N/A)

I admit I may have overstated my case with regards to environmental importance, but I hope I did emphasize equally both the relevance of the environment and a population’s phylogeny in other words, geneaology with regards to mutations. ❋ Unknown (2009)

The advent of Darwinism too, turned men's minds to "phylogeny", and biologists were busy establishing genetic relationships and tracing back the infinite variety of living types to the lowly root of the genealogical tree. ❋ 1840-1916 (1913)

[The remainder of this essay contains a discussion of questions of taxonomy and phylogeny, which is now antiquated. ❋ Thomas Henry Huxley (1860)

You indicated that two misunderstandings of phylogeny, first that distance is the sole measure, and second that natural selection was the cause of phylogenetic trees. ❋ Unknown (2010)
