It was Harry Govier Seeley, a palaeontologist trained in Cambridge under the renowned geologist Adam Sedgwick, who determined that dinosaurs fell quite neatly
into two distinct groupings, or
clades; Saurischia or Ornithischia.
Thus, the morphological similarities that led to their classification
into the same
clade are not the result of descending from a common ancestor, but reflect adaptations to related environments (convergent evolution).
«And we found that dingoes fall right
into the main domestic dog
clade,» Wilton says.
Although the CC97 strains from animals were quite genetically diverse, the human isolates cluster together in two tight, distinct «
clades,» or relatedness groups, indicating that S. aureus CC97 in cattle crossed over
into humans on two separate occasions.

Our analyses support the grouping of placozoans, cnidarians and bilaterians
into a eumetazoan
clade, with demosponges as an earlier - branching lineage25, and reject the diploblast — triploblast phylogeny17 in favour of a more conventional «sponges first» tree19, 20 (Fig. 1d).
This project produced data demonstrating that 185 CHIKV sequences associated with the 2014 Caribbean outbreak segregate
into 2 well - supported
clades, that multiple phylogenetic subclades are associated with clinical phenotypes, and that multiple international transmission events were observed.
The four putative - outbreak ST82 sequences fell
into two
clades, the two
clades were separated by ca 1,700 single nt polymorphisms (SNP) s when recombination regions were included but only by 12 to 21 SNPs when these were removed.
Even scarier is what Edward Dubovi, Ph.D., director, Virology Laboratory Animal Health Diagnostic Center, College of Veterinary Medicine, Cornell University, said: «We are sequencing all the time to determine if the H3N2 virus diverges
into different
clades (almost like substrains of flu).
Our divergence date estimates for the island fox
clade itself, ~ 9200 years ago, as Santarosae separated
into four distinct islands and for the southern island fox lineage, ~ 7100 years ago, correspond well with the earliest AMS dated island fox bones (~ 7100 cal BP for northern and ~ 5640 cal BP for the southern islands).
