(a.) Relating to evolution; as, evolutionary discussions.
Example Sentences:
(1) Gradual evolutionary change by natural selection operates so slowly within established species that it cannot account for the major features of evolution.

(4) The sequence data were used to infer phylogeny by using a maximum-parsimony method, an evolutionary-distance method, and the evolutionary-parsimony method.
(5) Since the four determining coefficients may change over evolutionary time-scales, the mathematical results together with a natural selection argument proves that virulence gamma 2 attenuates.
(6) For evolutionary biologists population variability per se has proven of interest.
(7) The results found with individual chromosomes in the different species also appear relevant, in the light of the evolutionary relationships between these nonhuman primates and man.
(8) Genetic distances were calculated to determine evolutionary relationships.
(9) Detailed information on the structure and regulation of MHC gene expression will be required to understand fully the biologic role of the MHC and the evolutionary relationships between species.
(10) In conclusion, DNA has been transferred sequentially from the chloroplast to the mitochondrion during crucifer evolution and there cpDNA sequences can persist in the mitochondrial genome over long periods of evolutionary time.
(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.
Evolutionist
Definition:
(n.) One skilled in evolutions.
(n.) one who holds the doctrine of evolution, either in biology or in metaphysics.
Example Sentences:
(1) Moreover, the evolutionists generally distinguish two situations (Dawkins, 1980; Maynard Smith, 1982): one in which fitness is independent of the frequency of the phenotypes present in the population (frequency-independent selection), and one in which it does depend on this frequency (frequency-dependent selection).
(2) The cross-species gene transfer model could help explain many observations which have puzzled evolutionists, such as rapid bursts in evolution and the widespread occurrence of parallelism in the fossil record.
(3) The nature of the last universal ancestor to all extent cellular organisms and the rooting of the universal tree of life are fundamental questions which can now be addressed by molecular evolutionists.
(4) The conquest of natural history by physics, in one and the same movement, leads to a subversion of physical geology by history, and prevents biology from becoming evolutionistic in the sense in which the nineteenth century understands this term.
(5) The main goal of the protein evolutionist is the reconstruction of past events leading to the structures of contemporary proteins.
(6) These new fossils, dates, analyses, and interpretations lead to confirmation and refinement of the mosaic scheme of human evolution as proposed by early evolutionists such as Lamarck, Haeckel, and Darwin.
(7) If he may be labeled an evolutionist, the specificity of his views must be taken into account.
(8) Later he came under the direct influence of the English evolutionists, and this was crucial for the conception of Ancient Society.
(9) Our results strongly support the Evolutionists' point of view.
(10) The main "evolutionist" issue that concerned him was that of the unity or diversity of the human species.
(11) The history of both problems, that were first given consideration by N.W.Timofeeff-Ressovsky, a known Russian radiobiologist and evolutionist, has been followed up.
(12) Indeed, evolutionists don't agree on how divergently our own biosphere could have developed if such contingencies as ice ages and meteorite impacts had happened differently.
(13) And many will blame the evolutionists for bringing the matter up in the first place.
(14) The authors think that the conventional conception, in which ontogenetic development is comparable with phylogenetic development, needs to be reconsidered: the cervical curvature is a prime curvature setting the evolutionist question about the origins of the rachidian curvatures.
(15) Unfortunately, evolutionists frequently regard them as competing theories that invoke different mechanisms, such that if one is "right" the others must be "wrong".
(16) The problem of multiple frameworks is aggravated by the fact that major terms, such as "units of selection", are defined differently within each framework, yet many evolutionists who use one framework to argue against another assume shared meanings.
(17) Darwin's proposal of two sources of instinct--natural selection and inherited habit--fostered among late nineteenth century evolutionists a variety of conflicting notions concerning the mechanisms of evolution.
