But what is even more certain, so that it becomes self - evident when we observe the revolutionary biological superiority of Thought over Instinct, is that if a given Phylum X, shall we say, preceding the anthropoids, had succeeded in passing the barrier separating reflective consciousness from direct consciousness, Man would never have come into existence: instead of him, Phylum X would have woven and constituted the Noosphere.

We see paws turned into pincers, paws equipped with hooves for running, burrowing paws and muzzles, winged paws, beaks, tusks and so on — innumerable adaptations giving birth to as many phyla, and each ending in a blind - alley of specialization.

The convergence of the phyla both ensues from, and of itself leads to, the coming together of individuals within the peculiarly «attaching» atmosphere created by the phenomenon of Reflexion.

The centers of consciousness, acquiring autonomy as they emerge into the sphere of reflection, tend to escape from their own phylum, which granulates into a line of individuals.

The critical point of Reflexion in the biological unit becomes the critical point of Inflexion for the phyla, which in turn becomes the point of «circumflexion» (if I may use the word) for the whole sheaf of inward - folding phyla.

In this new form, and having lost nothing of its physical reality (indeed, as much superior to its first state as the Noosphere is superior to the simple, isolated phylum) it acquires, by becoming exterior to the individual, an incomparable substance and capacity.

along certain prescribed lines (reduction or adaptation of limbs, complication of teeth, increased specialization as carnivores or herbivores, runners, burrowers, swimmers, flyers, etc.); and secondly dispersive, since the different phyla separated at certain points of proliferation, certain «knots» which we may suppose to be periods of particularly active mutation.

Phyletic in the first place: every species (or group of species) formed a sort of shoot (or phylum) which was obliged to evolve «orthogenetically» (The word «orthogenesis» is here used in its widest sense: A prescribed orientation offsetting the effect of chance in the play of heredity.»)

If, as we have shown, the social phenomenon is not merely a blind determinism but the portent, the inception of a second phase of human Reflexion (this time not merely individual but collective), then it must mean that the phylum is reconstituting itself above our heads in a new form, a new ramification, no longer of divergence but of convergence; and consequently it is the Sense of Evolution which, suppressing the spirit of egoism, is of its own right springing to new life in our hearts, and in such a way as to counteract those elements in the forces of collectivization which are poisonous to Life.

This accounts for the tendency, which has been insufficiently noted, of every living phylum (insect and vertebrate) to group itself towards its latter end in socialized communities.

In the meantime, the presence of the spirit of Christ and the «Christian phylum» (Teilhard) in this history make history, as such, always influenced by the partial realization of atonement, and the vision of fully realized divine - human unanimity which history approaches as a limit.

The «missionary» enterprise on this model thus becomes an identifying, a naming, and an explication of the structure of grace so as to facilitate its greater actualization in the lives of persons with all sorts of relations to the «Christian phylum» (Teilhard).

d The Christian phylum is not an accessory or divergent shoot in the human social organism, but constitutes the axis itself of socialization.

Biologists do not agree about the mechanism of the continual disappearance of phyla in the course of geological time, a process almost as mysterious as that of their formation; but the reality of the phenomenon is indisputable.

For if by its structure Mankind does not dissipate itself but concentrates upon itself; in other words, if, alone among all the living forms known to us, our zoological phylum is laboriously moving towards a critical point of speciation, then are not all hopes permitted to us in the matter of survival and irreversibility?

It probably does not apply to many, if not all, phyla, and possibly also not to many classes within the phyla.»

These arrow worms, which make up the phylum Chaetognatha, snatch prey with Wolverine - like claws protruding from around their mouths.

The new study, a collaborative effort by groups led by Professor Gert Wörheide (Chair of Paleontology and Geobiology at LMU) and Dr. Davide Pisani (Bristol University, UK) reaffirms the traditional view that the sponges were the first phylum to diverge from the common ancestor of metazoans.

All four phyla are evolutionarily ancient, and were already in existence more than 600 million years ago.

The answer to the question of whether the sponges or the comb jellies (also known as sea gooseberries) represent the oldest extant animal phylum is of crucial importance to our understanding of organismic evolution.

In subsequent studies the researchers plan to analyze further relevant datasets in order to test different scenarios of the evolution of the earliest animal phyla.

«Animal evolution: Sponges really are oldest animal phylum.»

Some 22 phyla of microbes call the human home, although just four — Actinobacteria, Firmicutes, Proteobacteria and Bacteroidetes — dominate.

As a biologist, she recognized the importance of mycorrhizal fungi and contributed to the description of a fungus in the Acaulosporaceae, a fungus in the same phylum as the species described in this paper.

Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

Many of the animals phyla that are losers in terms of present - day species numbers tend to be in the ocean, and because of human activity, they may go completely extinct.»

Animals have incredible variation in their body shapes and ways of life, including the plant - like, immobile marine sponges that lack heads, eyes, limbs and complex organs, parasitic worms that live inside other organisms (e.g. nematodes, platyhelminths), and phyla with eyes, skeletons, limbs and complex organs that dominate the land in terms of species numbers (arthropods) and body size (chordates).

They then tested how each trait was related to the number of species in each phylum, and to how quickly species in each phylum multiplied over time (diversification).

All animal species are divided among roughly 30 phyla, but these phyla differ dramatically in how many species they contain, from a single species to more than 1.2 million in the case of insects and their kin.

A fundamental but unresolved problem is whether the basic biology of these phyla is related to their species numbers.

«We tested all these unique traits individually,» Wiens explained, «for example, having a head, having eyes, where the species in a phylum tend to live, whether they reproduce sexually or asexually, whether they undergo metamorphosis or not; and from that we picked six traits that each had a strong effect on their own.

Cartwright said the confirmation that myxozoans are cnidarians would necessitate the re-classification of Myxozoa into the phylum Cnidaria.
