(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.

(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.
Vestige
Definition:
(n.) The mark of the foot left on the earth; a track or footstep; a trace; a sign; hence, a faint mark or visible sign left by something which is lost, or has perished, or is no longer present; remains; as, the vestiges of ancient magnificence in Palmyra; vestiges of former population.
Example Sentences:

(2) Cells and cell lines from malignant rat mammary tumours of increasing metastatic potential and from malignant areas of human ductal carcinomas largely fail to yield fully differentiated myoepithelial-like or alveolar-like cells in culture; however, weakly metastasizing rat cells yield variants which may retain a vestige of the myoepithelial phenotype.
(3) Many bacterial vestiges were probably retained in eukaryotes, mostly those related to the dominant and lasting role of small replicons in all their bacterial precursors.

(11) The library did not deem it appropriate to pay citizen Burovaya [Skorodumov widow] for the erotic literature, broadsheets and magazines, as this literature presents neither scientific nor historical value to the library’s readers, and is an especially harmful vestige of bourgeois ideology,” he wrote.
(12) "This is a world-first initiative designed to remove the last vestige of glamour from tobacco products," she told parliament.
(13) The cane mouse apparently is unique among the animals challenged so far in these ways in that it seems to have no vestige of reproductive photoresponsiveness.
(14) In all likelihood, however, few PAAs will be shown to produce a single "pure" activity and because there are some similarities in the different SARs (even though there are some very clear differences) it is not unreasonable to assume that many PAAs will produce more than one type of effect or will display vestiges of one or more different components of action.
