Phylogenetics
Phylogenetics is the study of evolutionary relationships among biological entities
-
often species ,
individuals (which to taxa)
or
genes may be referred as .
Why it's important ?
Be
Phylogenetics enriches our understanding of how genes , genomes , species evolve .
Be Helps understand how sequences came to be the
way they are today .
B. Enables us to predict how species will change in the future .
Applications of phylogenetics
me Classification : More accurate descriptions of patterns of
relatedness than was available before .
Be Forensics :
Helpful to evaluate DNA evidence presented in court
cases to inform situations e. paternity test food crime contamination
g. ,
.
B.
Identifying the origin of pathogens : Molecular sequencing and phylogenetics are used
to investigate pathogen outbreak .
e. g.
which species the pathogen is related to and the
likely source of transmission .
Be Conservation : Help inform conservation policy when conservation biologists have to make
tough decisions about which species they try to prevent from becoming extinct .
B.
Bioinformatics and computing Many :
of the algorithms developed for phylogenetics
have been used to develop software in other fields .
Phylogenetics and family tree
Historically trees were produced based on physical traits therefore inaccurate .
,
Family tree can be used to help understanding the phylogenetic tree and most recent
common ancestor .
An when comparing sequences there will only be

example of recombination of genetic material between organisms which
a breed with each other .
