(11) In 1868, Thomas Huxley suggested that Archaeopteryx was an evolutionary link between dinosaurs and birds.
(12) Statistical analysis of 251 phylogenetically informative nucleotide positions rejects the "volvocine lineage" hypothesis, which postulates a monophyletic evolutionary progression from unicellular organisms (such as Chlamydomonas), through colonial organisms (e.g., Gonium, Pandorina, Eudorina, and Pleodorina) demonstrating increasing size, cell number, and tendency toward cellular differentiation, to multicellular organisms having fully differentiated somatic and reproductive cells (in the genus Volvox).
(13) This approach is correct for the period of the new evolutionary synthesis, too.
(14) Our findings demonstrate that the amino acid sequence of neuromedin U is markedly conserved in species which have diverged millions of years ago in evolutionary terms.
(15) Conventional dietary categories, particularly frugivory, are inadequate for organizing the behavioral and anatomical evidence pertinent to evolutionary adaptation.
(16) Maximum power output for the fast muscle fibres from the Antarctic species at -1 degree C is around 60% of that of the tropical fish at 20 degrees C. Evolutionary temperature compensation of muscle power output appears largely to involve differences in the ability of cross bridges to generate force.
(17) We propose that human influenza A is unique in that it is the only virus group in which antibody selection dominates evolutionary change.
(18) If other techniques of phylogenetic analysis confirm this evolutionary tree, we propose that the photocytes be given urkingdom status.
(19) Kimura's estimate of evolutionary distance, K, is 0.353, while those of Miyata and Yasunaga are KS = 0.708 and KA = 0.171.
(20) In order to understand the evolutionary history of the B sheep locus, we have sequenced the beta B gene from these sheep, and the beta C gene from A-haplotype sheep, and compared the sequences to those of the sheep beta A, goat beta C, and beta A, and cow adult beta genes.
Phylogeny
Definition:
(n.) The history of genealogical development; the race history of an animal or vegetable type; the historic exolution of the phylon or tribe, in distinction from ontogeny, or the development of the individual organism, and from biogenesis, or life development generally.
Example Sentences:
(1) The sequence data were used to infer phylogeny by using a maximum-parsimony method, an evolutionary-distance method, and the evolutionary-parsimony method.
(2) The only inconsistency in the mariner gene phylogeny is in the placement of the Zaprionus mariner sequence, which clusters with mariner from Drosophila teissieri and Drosophila yakuba in the melanogaster species subgroup.
(3) The unique structure of these cilia has systematic and phylogenetic significance for the Acoela, and it is argued that ultrastructural characters in general, including characters of organelles, can be validly applied to the phylogeny and systematics of the Metazoa.
(4) In general, more than five loci are needed to resolve the species phylogeny.
(5) Genetic control of hormone receptors is analyzed by studying changes in their characteristics during the ontogeny, phylogeny, and malignant transformation of cells.
(6) Ecological changes on the main stem of the phylogeny are abrupt and associated character states consequently well differentiated.
(7) The data about genomic and protein sequences could provide bases to complement or expand the rRNA-based phylogeny.
(8) Therefore a primitive symmetrodont molar pattern was probably present in the phylogeny of pantotherian and tribosphenic molars.
(9) Recently published amino acid sequences are compared to those of other cytochromes c. Molecular phylogenies constructed by using an ancestral sequence method are compared to the classical biological view of invertebrate evolution.
(10) Cladistic analysis of likely phylogenies within the neurotrophins shows BDNF and NT-4 to be most closely related whereas NGF may be the sister group to NT-3, BDNF, and NT-4.
(11) The most interesting results of single gene phylogenies have been the anomalies, such as insulin in hystricomorphs or cytochrome c in the rattlesnake.
(12) Legitimacy of the symbiont transfer theory removes the constraint of interpreting presence of cellulolytic protozoa as a synapomorphy between Cryptocercidae and Isoptera, with potential impact on objective resolution of dictyopteran phylogeny.
(13) Phylogenetic trees based on aa sequences and nt sequences are similar, but not completely congruent with rRNA gene-based phylogenies.
(14) Differentiation of various areas of the proximal part of the nephron proceded in phylogeny with different intensity and the maximum specialization was characteristic of the most proximal portion of this part of the nephron.
(15) Three hypotheses are proposed on the relationship between the evolution of the 5.8S rRNA and the phylogeny of Diptera.
(16) The resulting tree is compared with the eubacterial phylogeny built on 16S rRNA catalog comparison.
(17) It is now clear that phagocytically stimulated hemocytes of several molluscan species can generate reactive forms of oxygen; the relevance of this fact for the phylogeny of killing systems operative in leukocytes is discussed.
(18) Given the discrepancies generated by this classification by analogy, we evaluated a classification using a phylogeny congruence analysis of the compositional relatedness of vertebrate PK's.
(19) In the case of explicit morphological phylogenies, ecological and behavioural data can be integrated with them and it may then be possible to decide whether morphological characters are likely to have been elicited by the environments through which the clade has passed.
(20) We have undertaken the construction of a broad molecular phylogeny of protists through the comparison of 28S rRNA molecules.
