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

Transitions of Reptiles to Mammals A long long time ago‚ in a galaxy not too far away‚ was a little blue planet called Earth‚ and on this world not a single mammal lived. However a lot of time has past since then and we now have lots of furry creatures that are collectively called mammals. How did they get their? Where did they come from? These are the kinds of questions that led me to my subject of choice. I will endeavor to provide examples‚ using specific transitional fossils‚ to show that

“On land‚ tropical forests underwent reduction or‚ more commonly‚ broke up into mosaics where patches of forest were interspersed with savanna or other types of open country. With the breaking up of forests‚ our early ancestors found themselves spending more and more time on the ground and had to adapt to this new open environment.” There are many different theories trying to explain why and how our ancestors came to be bipeds. This quote is stating the theory that our ancestors faced many obvious

sapiens). Current understanding of human origins is obtained largely from the findings of paleontology‚ anthropology‚ and genetics. Of all primates‚ humans share particularly close affinity to other members of a group known as hominoids‚ or apes. Humans and their immediate ancestors‚ known as hominids‚ are notable among hominoids for their bipedal locomotion (Using two legs for walking)‚ slow rate of maturation‚ large brain size‚ and‚ at least among the more recent hominids‚ the development of
