How can you use “ecdysozoa” in a sentence? Here are some example sentences to help you improve your vocabulary:
The first hypothesis corresponds to the traditional grouping Coelomata and the second corresponds to Ecdysozoa [ 3 ] . For convenience, we will use these names in reference to the two hypotheses while recognizing that this study, by necessity, involves only a subset of all animal phyla.
Using the Shimodaira-Hasegawa (SH) test [ 17 ] , this maximum likelihood topology was significantly different from the alternative hypotheses of Ecdysozoa ( P < 0.001) and Hypothesis III ( P < 0.001).
For example, the original support for Ecdysozoa was obtained only with a particular genus of nematode, Trichinella, that had a short branch in the 18S rRNA tree [ 3 ] . To test this, phylogenies were constructed using different species of nematodes.
The traditional view is that arthropods are more closely related to annelids than to nematodes, but some recent molecular phylogenies place nematodes and arthropods together in a high-level taxon named Ecdysozoa, which does not include annelids [ 24 25 ] . Other molecular studies give conflicting results [ 26 27 ] . Regardless of the evolutionary relationship between Nematoda and Arthropoda, C. elegans and Drosophila remain useful and valid models for our analyses, and the relationships shown in Figure 1are consistent with both hypotheses.
The Coelomata hypothesis was significantly supported (≥ 97% bootstrap support, posterior probabilities = 1.0; Ecdysozoa rejected by SH test, P < 0.006; Hypothesis III rejected by SH test, P < 0.027) using either a genus in a different order, Brugia (18 proteins), or Trichinella (six proteins) (Fig.
