Summary Introduction

To explain: The reasons that would make a researcher choose one technique of developing phylogenies from DNA sequence data over another amongst parsimony, maximum likelihood, and Bayesian inference.

Introduction: Evolution is a continuous process and different methods have been developed to establish significant evolutionary relationships between different species. Based on the requirement and the method adopted, molecular and morphological data is analyzed and inferred for the development of the phylogenetics. Some of the methods that are used for development of the phylogenetic tree are parsimony method, maximum likelihood method, and Bayesian method.

Summary Introduction

To explain: Advantages and disadvantages of parsimony, maximum likelihood, and Bayesian inference method for developing phylogenies.

What is needed for an idea to be scientifically reliable?
A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans. After doing DNA analysis, they determine that the organisms share the following percentages of DNA: Organism A and humans share 85% of their DNA. Organism B and humans share 80% of their DNA. Organism C and humans share 90% of their DNA. Based on this information, which order should they go on the cladogram (from least related to most related)?
Construct a cladogram that provides one hypothesis about the evolutionary history for these 6 taxa. Be sure to map each of the character states for every taxon represented in the character matrix. See tips below to help get you started.  You can insert a photo of a hand drawn cladogram or create one on your device. Keep in mind that cladograms are hypotheses, there are many different cladograms that can be constructed. a) Which characteristics were identified as homoplasies on your cladogram?  b)
