"Phylogenetic relationships" refers to the evolutionary connections or family ties between different organisms or species, showing how they are related to each other in terms of their common ancestry and how they have evolved over time.

Further, if the group being studied is only known from fossil evidence (e.g., mosasaurs), then morphology is the only informative data set
on phylogenetic relationships and paleobiology.
Today, many ecological and evolutionary studies depend on a wide range of molecular tools to
infer phylogenetic relationships, uncover population structure within species, and track quantitative traits.
To
examine phylogenetic relationships between island, California and eastern gray foxes, additional publically available mammal mitogenomes were obtained from GenBank and aligned to the fox dataset.
«If we are to understand the evolution of certain key features of animals, such as their nervous systems, tissue organization and organs, we first have to clarify the
early phylogenetic relationships» Wörheide explains.
Our project seeks to uncover the as - of - yet
unresolved phylogenetic relationship of bark and ambrosia beetle - associated fungi, and use this framework to address questions that link patterns of fungal genome evolution with large - scale beetle ecology.
These include: 1) finding and describing new fossils in Precambrian strata, 2) using analytical tools to examine those fossils in order to determine taxonomic affinity, taphonomy, functional morphology, and paleoecology, 3) using modern analogs to
determine phylogenetic relationships and physiology of early eukaryotes and animals, and 4) combining multiple sources of data to create a timeline of biotic and abiotic events in the Precambrian.
In case you didn't follow the link, it's to a series of articles abstracted in PubMed on
the phylogenetic relationships between red deer, sitka deer, and wapiti (the American elk).
Macroevolution is further supported in
the phylogenetic relationships of extant organisms (including the concordant phylogenetic relationships of ERVs and other parasitic genetic elements).
«Despite an inability to demonstrate the monophyly of all Strombus subgenera,
phylogenetic relationships inferred here using molecular data generally support the taxonomic classifications proposed by Abbott.»
The paper, titled: «A new basal sauropodiform from South Africa and
the phylogenetic relationships of basal sauropodomorphs,» was published online on Tuesday, 23 June 2015.
Steve: Now, this particular group was being led by this very animated woman who was talking about birds and turtles and
their phylogenetic relationships.
Using this data, studies analyzed
the phylogenetic relationship of birds and explored aspects of avian biology.
«Based on
the phylogenetic relationships and the presence of tetrachromacy in recent tetrapods it is most likely that the stem species - of all terrestrial vertebrates had photo receptors to detect blue, green, red and uv,» says Dr. Christian Fischer of the University of Göttingen.
The study, published as the cover article in BioMed Central's Avian Research, led by the Earlham Institute and the Museum of Vertebrate Zoology at the University of California, explores
the phylogenetic relationship between two forms of Harriers (Circus cyaneus); the Eurasian Hen Harrier (C. c. cyan ecus) and the American Northern Harrier (C. c. hudsonius) to distinguish their ancestry and evolution.
Sequencing technology did not affect the percentage of sequence sets aligning to the genome as much as
the phylogenetic relationships among the species.
«This acknowledges differences but does not discuss
their phylogenetic relationship.
Besides this, we resequenced 11.74 kb of the SLC24A5 gene in a global sample set, to assess the world - wide diversity, selection patterns and study
the phylogenetic relationships between the populations.
Although many aspects of core Caryophyllales have been thoroughly investigated during the past several decades (e.g., chemistry by Mabry and colleagues, pollen by Nowicke and colleagues, wood anatomy by Carlquist and colleagues), revised views on
the phylogenetic relationships of Caryophyllales require renewed efforts to identify synapomorphies and to reconstruct patterns of morphological, chemical, and anatomical evolution.
Phylogenetic relationships and generic affinity of Uncinula septate inferred from nuclear rDNA sequences.
