Rizal Technological University Investigatory Study (Kingdom Animalia) Written by: Rodette Joyce Laurio Submitted to : 1 Introduction In biology‚ kingdom is a taxonomic rank‚ which is either the highest rank or in the more recent three-domain system‚ the rank below domain. Kingdoms are divided into smaller groups called phyla (in zoology) or divisions in botany. When Carl Linnaeus introduced the rank-based system of nomenclature into biology‚ the highest rank was given the name

that showed signs of early evolutionary development that is connected to Homo sapiens in the evolutionary tree. Lucy and Ardi are important to our evolutionary development because they were the first fossils to show upright walking as their primary locomotion. American paleoanthropologist‚ Dr. Donald Johanson‚ led the team that discovered Australopithecus Afarensis in 1974 at Hadar in the Awash Valley in Ethiopia. The discovery of Lucy was very significant‚ which was because the skeleton showed evidence

What defines us as humans? Calling ourselves human is our way of categorizing ourselves as a superior species. Although we are distinctly different‚ we should accept that we are in the same family as chimpanzees. Acknowledging that fact doesn ’t mean you are calling yourself a chimp. For example‚ a dog isn ’t a wolf even though they are from the same family. We are humans. What is it about our physical and behavioral traits that enable us to develop uniquely human capabilities? Traits like language

Professor Arnie Schoenberg 11/2/2014 SDCCD Test #2 1. What are the major trends in hominin evolution? Major Trends in Hominin Evolution are diet‚ cultural evolution‚ encephalization‚ language and speech Diet; In addition to forcing changes in locomotion that led to walking upright‚ the increasingly dry climate of east Africa over the last six million years forced changes in the diet of early hominins from the soft fruits of the tropical rain forest to the increasingly fibrous and tough foods available

current evidence‚ Lucy was not an upright walking species‚ she most likely was a tree climber because her joints were made for it. Further‚ she did not have human-like hands and feet‚ she had long curved fingers and toes representative to arboreal primates than any other species. Yet‚ there are some sign that there were some differences. The important question to ask is‚ was Lucy just another cousin of the current apes which went extinct before her cousins or was she their ancestor. Simply stated

which stands for “southern ape of the Afar region”. This genus was one of the earliest species of hominids; the family of bipedal primates also includes homo hablis and homo erectus. While Australopithecus and Homo species vary in many ways‚ both hominids share common characteristics that define them as a group. The most distinct of these traits is bipedal locomotion‚ which means

function of the sacrum is to provide attachment for the iliac (hip) bones and protect the pelvic organs. Coccyx region –the four fused bones of the coccyx or tailbone don’t really have a function. It is an embryology remnant of a tail from our primate ancestors. Types of Bones Long Bones – These have a greater length than width‚ with growth plates (epiphysis) at either end‚ having a hard outer surface of compact bone and a spongy inner known as cancellous bone containing bone marrow.

The base of the tail is slender‚ and the caudal fin strongly divided. Primarily swift predators of open seas; some of the smaller species strain zooplankton through their gill rakers. Example of a Scombridae. This one’s a mackerel. Mode of locomotion is Thunniform: Most fishes move by generating an undulating wave along their bodies along their bodies that pushes water backwards but thunniform swimmers isolate this movement to
