Dictionary » P » Phylogenetics




(1) The study of phylogeny.

(2) The study of evolutionary relatedness among various groups of organisms through molecular sequencing data and morphological data matrices.


Word origin: Greek from the terms phyle/phylon (meaning "tribe, race,") and genetikos (meaning "relative to birth" from genesis ("birth").

Mutuation saturation at a particular locus

... that it occurs most in hyper-variable regions like in mitDNA, but what effect does this have on comparing two species in the context of molecular phylogenetics? Thanks in advance!

I have a problem seeing the bigger picture of research

It looks like the problem is with figuring out what is the use of your work. DNA sequencing of a species can yield quite a bit of new knowledge. Phylogenetics is one thing, comparison to a more well-studied species to understand how they are different. But the other possible aspect is to study ...

Re: Why is knowledge on phylogeny important

... likely to occur when the reservoir host and potential novel host are phylogenetically close (e.g., Perlman & Jaenike 2003). So in this case phylogenetics might aid to assess where certain bumble bee species can be introduced (in regions where the wild bumble species is a rather distant relative) ...

Clade v. Phylum

... What I'm confused about is how a clade relates to what mono- para- and poly phyletic groups are about and the difference between cladistics and phylogenetics... sorry for the confusion... all the words that sound so similar have me confused... :/ Thanks! M.

Re: Theories - Origin of Life

... to establish these lineages they get different results depending on which gene or protein they use. This happens without HGT sequences. See above. Phylogenetics is a complicated endeavour that requires a very careful selection of sequences. Hence the concept of HGT was formulated to explain away ...
