    Owing to a great deal of experimental research worldwide, the sub-cellular databases at a molecular and genetic level have expounded resulting in greater availability of multidimensional information. This has posed a prodigious challenge for evolutionary biologists to decode the information in a meaningful and logical manner for various applications. Concomitantly, the advancements in computational techniques and the development of improvised algorithms enabled biologists to decipher the intricacies of the cellular and molecular evolutionary patterns, species adaptation, and their diversification from the data at their disposal. Consequently, statistical data analysis has gained wide popularity among evolutionary biologists for deriving reliable interpretations based on the phylogenetic analyses and the exchange of ideas on the methodological development has gained greater importance.

    Importance of Phylogenetic in microbiology

    Luciano Brocchieri

    Phylogenies are significant for tending to different organic inquiries like connections among species or qualities, the root and spread of viral disease and the segment changes and relocation examples of species. The progression of sequencing advancements has taken phylogenetic investigation to another stature. Phylogenies have penetrated practically every part of science, and the plenty of phylogenetic techniques and programming bundles that are presently accessible may appear to be overwhelming to an exploratory scientist. Here, we audit the significant strategies for phylogenetic examination, including miserliness, distance, probability and Bayesian techniques. We talk about their qualities and shortcomings and give direction to their utilization.

    Craniometry Patterns of Nigerians and its Correlation with Chronological age

    Vidona WB, Oviosun A and David LK

    Cranial dimensions and cranial indices are considered as the simplest and most efficient way to indicate facial differences and age variations. Cranial morphology and dimensions are used to evaluate various aspects of growth and development thus helping in population differentiation.

    Aim: the study is to investigate the craniometrical patterns in the Nigerian population-based on three-dimensional computed tomographic data, with the objectives of determining the age of individuals in the eastern part of Nigeria as well as determining if the skull of individuals varies with age using computed tomography. 

    Methodology: involves a descriptive study design with age determined using standard aging techniques. 150 dry adult human skulls cases (male and female both) constituted the material for the present study between the age group of 25-60 years. Data were scanned in the radiology department and the CT data were processed in a computer workstation at the department. The CT scan acquisition was performed with 1.5mm slice thickness and reconstruction was done with 1.0 m 2 m slice thickness. All the CT data were recorded using DICOM 3.0 as a medical image file format into CD-ROM. The segmentation techniques were used to identify the region of interest of the computed tomography image based on the Hounsfield unit. The selected region was calculated into a 3-D modem based on the traditional definition with the modification into 3D model. The anatomical landmarks in the craniometrics study were: Glabella (GL), Bregma (BR), Opisthocranium (OPC), Nasion (NA), Basion (BA). The measurements were interpreted using statistical analysis and reported in form of a comparison of the mean values and mean difference, standard deviation, and confidence interval in respect to the various landmarks. Analysis of variance was utilized with a p-value 0.005 alpha level of significance.

    Result: the total number of samples for each landmark group is 1050 which covers the range value of 6 with a minimum number 1 and maximum number 7. The total sum of all Landmarks d is 4,200. The mean statistics of the seven groups is 4.00 with a standard error of 0.62. The total length is 1050 with a range of 119. The length attracts the minimum and maximum values of 80 and 199 with a total sum of 132282. The mean statistics is 125.98 with a standard error of 0.740.
