1. Did the construction of the phylogenetic tree based on the 14 living Caminalcules change the way you would group Caminalcules species in your taxonomic classification (chart)? What does this suggest about classification based on strictly of similarity versus evolutionary relationship? The phylogenetic tree was more of an evolutionary tree. It showed the evolution of the organisms and their ancestors or traits that they branched off of. The chart however just simply organizes and separates the
the medical aspects and applications of mammalian genetics, such as specific types of cancer genetics or stem cell differentiation, my topic will discuss perhaps the not as applicable, but by no means less interesting radiation, biodiversity, and phylogenetic relationships among cetaceans. This topic is of major interest to me because of my fascination with the origin and evolution of life on earth. When I was younger I had an ambition to become a paleontologist and study prehistoric life, particularly
Citation MLA Zachos, Frank E. "Tree Thinking and Species Delimitation: Guidelines for Taxonomy and Phylogenetic Terminology." Mammalian Biology 81.2 (2015): 185-88. Web. In your own words, what was the main focus of the article? There are multiple interpretations concerning how phylogenetic trees are built and the understanding of the phylogenetic species concept. A common mistake when it comes to interpreting phylogenetic trees, which portray evolutionary relationships among taxa. Generally it
boundaries. What gene flow does is that it introduces new alleles to a population, thereby reducing the differences among the population. Finally there are 2 schools of philosophies that are used to classify species, evolutionary systematics and phylogenetic systematics. Evolutionary systematics is a more holistic way to study evolutionary relationships while observing the
Caledonia (with 16 spp.) are considered to be centres of diversity for the genus. The New Zealand group includes six root climbing vines (M. albiflora, M. carminea, M. colensoi, M. diffusa, M. fulgens, and M. perforata), one shrub (M. parkinsonii) and five tree species (M. bartlettii, M. excelsa, M. kermadecensis, M. robusta, and M. umbellata) (Dawson, 1988). New Zealand is
Results Results of the first PCR reaction and gel electrophoresis with all primer sets can be seen in image 2. The first well contained the molecular weight marker, well 2; primer set 1, well 3; primer set 2, well 4; primer set 3, well 5; primer set 4 and well 6; primer set 5. The primer bands can be seen to have run to the end of the gel in wells 2 through 6, however no cDNA band were visible, only the weight maker bands were seen in the first well. The process was redone with a lower annealing
Hexapoda tree was in fact monophyletic (Reiger et al., 2004). Recent mitochondrial genomic sequencing data has shown that wingless collembolans and diplurians may not be as related to hexapods as originally thought (Sasaki et al., 2013).Based on the same mitochondrial genomic data, it has been inferred that collembolans and diplurians are more related to crustaceans (Sasaki et al., 2013). However, when nuclear molecular data such as rDNA and protein coding genes were analyzed for phylogenetic analysis
the Amaranthaceae family is placed in the order Caryophyllales. It includes the plants formerly treated as the family Chenopodiaceae [19]. The monophyly of this new, broadly defined Amaranthaceae is supported strongly by both morphological and phylogenetic analyses [11]. Despite the interest in the taxonomy and classification of the family Amaranthaceae, there is still need to study its phylogeny. The present study shows that a considerably level of similarity exists amongst the taxa (Figure 1 and
Homology is a central concept within the field of phylogenetics. It represents the idea of similarity in structure or anatomical position between organisms, indicating a common origin. Homology is traditionally contrasted with analogy; the similarity of function in two structures that have contrasting origins. However, it is now more common for the concept to be contrasted against homoplasy; a character shared by a set of species that their common ancestor does not possess. The concept of homology

Proceedings of the Sixth International Conference on Serpentine Ecology: 329-40 This paper was very useful in that it tested the limits of which plants could grow in serpentine soils. It also included the ecological advances that this type of soil causes such as adaptations and speciation of plants
