006 - Phylogenetics
Paul Andersen discusses the specifics of phylogenetics. The evolutionary relationships of organisms are discovered through both morphological and molecular data. A specific type of phylogenetic tree, the cladogram, is also covered.

Phylogenetics of HIV
Roadrunner is helping scientists study the HIV "family tree."
Glossary of Terms:
HIV stands for Human Immunodeficiency Virus, the virus that causes AIDS.
Acute HIV is the period immediately following exposure when the virus grows in the body and establishes the infection. When the immune response flares up sufficiently those infected will experience flu-like symptoms.
Chronic HIV is the second stage of the infection, marked by a strong immune defense and a reduced number of HIV particles in the bloodstream. This stage can last from two weeks to a few decades.
Phylogenetics is the study of genealogical or evolutionary connections among various groups of organisms (for example, individuals, species, or populations), revealed by molecular sequencing as well as physical characteristics.
A phylogenetic tree is a branching structure that depicts the genealogical or evolutionary connections.
DNA stands for deoxyribonucleic acid, the molecule that contains an organism's genetic information.
Sequences refer to the order of the nucleotide bases—adenine, guanine, cytosine, and thymine—in a molecule of DNA.
Amino acids are the organic compounds that form the basic building blocks of proteins.

In biology, phylogenetics (
/faɪlɵdʒɪˈnɛtɪks/) is the study of evolutionary relation among groups of organisms (e.g. species, populations), which is discovered through molecular sequencing data and morphological data matrices. The term phylogenetics derives from the Greek terms phyle (φυλή) and phylon (φῦλον), denoting "tribe" and "race"; and the term genetikos (γενετικός), denoting "relative to birth", from genesis (γένεσις) "origin" and "birth".
Taxonomy, the classification, identification, and naming of organisms, is richly informed by phylogenetics, but remains methodologically and logically distinct. The fields of phylogenetics and taxonomy overlap in the science of phylogenetic systematics — one methodology, cladism (also cladistics) shared derived characters (synapomorphies) used to create ancestor-descendant trees (cladograms) and delimit taxa (clades). In biological systematics as a whole, phylogenetic analyses have become essential in researching the evolutionary tree of life.
Evolution is regarded as a branching process, whereby populations are altered over time and may speciate into separate branches, hybridize together, or terminate by extinction. This may be visualized in a phylogenetic tree.

Biology 09-5 Cladistics and Phylogenetics
This video describes how evolutionary theory has influenced our approach to classifying living organisms, and how common ancestry explains the shared traits present in many lineages of living organisms. This video also compares the practices of cladistics and phylogenetics as tools for classifying living organisms, with examples on how to build an evolutionary tree using genetic and morphological similarities.

006 - Phylogenetics
Paul Andersen discusses the specifics of phylogenetics. The evolutionary relationships of organisms are discovered through both morphological and molecular data. A specific type of phylogenetic tree, the cladogram, is also covered.

Phylogenetics of HIV
Roadrunner is helping scientists study the HIV "family tree."
Glossary of Terms:
HIV stands for Human Immunodeficiency Virus, the virus that causes AIDS.
Acute HIV is the period immediately following exposure when the virus grows in the body and establishes the infection. When the immune response flares up sufficiently those infected will experience flu-like symptoms.
Chronic HIV is the second stage of the infection, marked by a strong immune defense and a reduced number of HIV particles in the bloodstream. This stage can last from two weeks to a few decades.
Phylogenetics is the study of genealogical or evolutionary connections among various groups of organisms (for example, individuals, species, or populations), revealed by molecular sequencing as well as physical characteristics.
A phylogenetic tree is a branching structure that depicts the genealogical or evolutionary connections.
DNA stands for deoxyribonucleic acid, the molecule that contains an organism's genetic information.
Sequences refer to the order of the nucleotide bases—adenine, guanine, cytosine, and thymine—in a molecule of DNA.
Amino acids are the organic compounds that form the basic building blocks of proteins.

Practical 4 - part 2: Making and Displaying Trees
- Make trees using tree annotator
- - burnin=1000 (10%)
- - note for SPREAD need to set probability at 0 so all nodes are annotated
- Display trees in fig tree
- -set dates and get time scale right (last date is 2014.342 = 6 May 2015), need to “reverse” time scale (due to coalescent theory)
- -show colours of host trait and region trait
- output to pdf and png

This video describes how evolutionary theory has influenced our approach to classifying living organisms, and how common ancestry explains the shared traits present in many lineages of living organisms. This video also compares the practices of cladistics and phylogenetics as tools for classifying living organisms, with examples on how to build an evolutionary tree using genetic and morphological similarities.
