Phylogeny is the evolutionary history of a particular group of organisms or their genes. Phylogeny can be represented in a phylogenetic tree which graphically represents the lines of descent among organisms or their genes. Learn more at 23andme.com.

What is phylogenetics?
based on natural evolutionary relationships Answer Phylogenetics is the study of the closeness/relatedness of genetic codes.
What two types of dating techniques are used in dating fossils?
Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave fossils. Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating, which provides absolute dates that are accurate to within 0.5%, but more often paleontologists have to rely on relative dating by solving the "jigsaw puzzles" of biostratigraphy.Classifying ancient organisms is also difficult, as many do not fit well into the Linnean taxonomy that is commonly used for classifying living organisms, and paleontologists more often use cladistics to draw up evolutionary "family trees". The final quarter of the 20th century saw the development of molecular phylogenetics, which investigates how closely organisms are related by measuring how similar the DNA is in their genomes. Molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend.
What are the types of animal scientists?
- Cell biologists: Study animal cells and their functions - Ecologists: Study animals and their interactions with their environments and humans. - Conservation biologists: Control and manage animal populations and their habitats. - Physiologists: Study how animals function and how they are adapted to live in their environments. - Systematists: Study evolutionary relationships between living and fossil animals and categorise animals. - Palaeontologists: Study evolutionary relationships between fossil animals - Taxonomists: Discover and describe new species or animal groups. - Entomologists: Study insects. Some study the roles and control of insect pests. - Herpetologists: Study amphibians and reptiles - Ornithologists: Study birds - Mammalogists: Study mammals - Parasitologists: Study parasites - Epidemiologists: Study the spread of diseases. - Ethologists: Study animal behaviour - Ichthyologists, Fisheries biologists: Study fish, fish populations and ways of growing fish and other aquatic animals - Aquaculturists: Study fish populations and ways of growing fish for commercial use. - Geneticists: Study the genetics of animals - Developmental biologists: Study the genetics of animals and how animals develop and grow. - Animal nutritionists: Study the diets and digestive capabilities of animals. - Animal photographers and illustrators: Produce photos and drawings of animals for books, films etc. - Consultants: Advise others on animals and the environment. - Writers and producers: Inform others about animals and the environment through journalism, books and films.

Where can one research more information base on phylogenetics?
There are several online sites where one can research more information on phylogenetics. Some of these online sites are "Wikipedia", "Researchgate", and "Bioinformatics".
What are the importance of phylogenetics?
means with the genetic codes we can classifiy the organisims
What is the word for an organism's evolutionary history?
The word is phylogenetics or phylogeny.
What do you call the study of putting plants and animals into groups?
There are a few terms used; taxonomy, systematics, cladistics, (biological) classification and phylogenetics. Taxonomy is the broadest term.
What genetic algorithms are known so far by researchers?
Some genetic algorithms that are known so far by researchers are bioinformatics, phylogenetics, economics and chemistry. There are many genetic algorithms known.
What does evolution biologist do?
Works on studies of genetics, phylogenetics, cladistics, evolutionary theory and experimentation, population genetics, systematics and molecular evolution, to name a few fields a evolutionary biologists works in.
What is one new line of evidence supporting evolution that scienists learned after Darwin's book was published?
One particularly powerful one is from molecular phylogenetics and virology - the evidence from endogenous retroviruses. See the links.
What is the difference between modern methods of classification and traditional methods of classification?
Modern classification is based on evolutionary relationships between organisms while traditional classification is not.
What area of taxonomy classifies organisms based on common ancestry?
Phylogenetics classifies organisms based on common ancestry by analyzing their evolutionary relationships using genetic data. This field of study helps to understand the evolutionary history and relatedness among different species.
What does modern classification identify?
Modern classification identifies organisms based on their evolutionary relationships, genetic similarities, and shared characteristics. This approach, known as phylogenetics, groups organisms into hierarchical categories that reflect their common ancestry and helps us understand the relationships between different species.
Who is the parsimony character and secondary character?
In phylogenetics, the parsimony character is the one that requires the fewest evolutionary changes to explain a given set of data. A secondary character is one that is less informative for resolving evolutionary relationships among organisms but can provide additional information when combined with other characters.
