According to the phylogenetic tree of life, the archaea are more closely related to the eukarya than they are to the bacteria, even though both archaea and bacteria are considered prokaryotes, and eukarya are eukaryotes. Explain how the ...
Explain how an outgroup is used to build a phylogenetic tree. In other words, explain what problems you have if you tried to build a phylogenetic tree. What do nodes in phylogenetic trees indicate? What's the difference between a phylogenetic tree and a cladogram? What are the distinguishing...
A botanist is studying the phylogenetic relationships of plants using only their their morphological traits. Would specialized plants (like desert or rainforest plants) complicate this process, why or why not? Explain. What is the purpose of a phylogenetic tree? Why is it important t...
From extraordinarily simple assumptions about the birth-death dynamics of individuals a wide range of implications are derived for different properties of ecological communities from, for instance, the shape of phylogenetic trees to the geographic distribution of species in space and time.(53) We have...
Bootstrap analyses of maximum parsimony trees revealed a tree with bootstrap probabilities of at least 99% for each branch. If we excluded third codon positions, the branching order of whale, cow and seal changed to a biologically not accepted topology. This observation questions the widespread ...
In the ‘NOVA LABS; The Evolution Lab,’ we found that creating a phylogenetic tree can show how different species are related to each other. A simple body part, like a vertebrate, can put species into a certain group. This means that history can prove that species do change over time ...
This route is particularly attractive for the systematics of organisms for which there is already a widely accepted phylogenetic placement in the TOL (primarily multicellular eukaryotes), but it has also had appeal for prokaryote phylogenetics. An obvious pro- blem is that the species tree has to ...
First, the African population is basal in the phylogenetic tree, whereas the Arabian clades are derived and nested within the African population. This is in congruence with previous molecular studies on the origin of hamadryas baboons (Wildman et al., 2004, Winney et al., 2004) and also ...
What are the taxonomic categories used to describe organisms? What is considered during phylogenetic classification? (a) What are subspecies? (b) How do they differ from species? What does "phylogenetic relatedness" mean? What is the significance of placing related groups ...
Briefly explain how forensic anthropology was important to the identification of victims of the Daegu subway disaster. Anthropology: Anthropology is the study of humans and human behavior. It is a broad field of academic disciplines that includes culture, socie...
