    species. The first name is the genus and the second name which follows the generic name and distinguished the species from others which are in the same genus (Swafford, 2016). Name have always been given to items such as plants, animals and fungi however Carolus Linnaeus was the scientist who came up with a hierarchal structure which shows its name as well as its phylogenetic name. Even though this classification system is set in place the name of a species can change and be re- evaluated due to phylogenetics and not phenetics (Science,2009) This means names of species names may change due to genetic information showing how close or how far apart certain species are. ( Science,2009). Kingdom Animalia Phylum Chordata Class Mammalia Order Monotremes Family Tachyglossidae Genus Zaglossus Kingdom - Animalia Every animal comes under the kingdom of Animalia which is also known as Metoza.

  • Essay On Marsupials

    Evidence from the differences in teeth structure has provided evidence for the differentiation of marsupial and placental mammals. Fossil records have a general consensus that with maturation, marsupial’s third premolars and post canine check teeth are the only teeth to be replaced. This feature is observed in fossils dating back 95-100 million years ago. The analysis of morphological evidence has established a stronger relationship between marsupials and placental mammals than monotremes…
