Comparison between cat and human skeleton

Cat skeleton Cats have seven cervical vertebrae like almost all mammalsthirteen thoracic vertebrae humans have twelveseven lumbar vertebrae humans have fivethree sacral vertebrae humans have five because of their bipedal postureand, except for Manx cats and other shorter tailed cats, twenty-two or twenty-three caudal vertebrae humans have three to five, fused into an internal coccyx. The extra lumbar and thoracic vertebrae account for the cat's enhanced spinal mobility and flexibility, compared to humans. The caudal vertebrae form the tailused by the cat as a counterbalance to the body during quick movements.

Australopithecus africanus -- The word "Australopithecus" means "southern ape. Raymond Dart, professor of anatomy at Witwatersrand University in Johannesburg, was the first to study these fossils. In at Taung in South Africa, Dart discovered a fossil skull consisting of a full face, teeth and jaws, and an endocranial cast of the brain.

The brain size was cc. Its age is currently felt to be around two to three million years old. Dart was convinced that some teeth were man-like and thus concluded a transition between apes and man.

His opinions on the matter of this particular skull were largely scorned by the scientists of this time who considered it nothing more than a young chimpanzee now considered to be about three years of age. The skull was soon known derisively as "Dart's baby. With Piltdown Man's human cranium and apelike jaw, it was hard to reconcile it to the Taung Child.

Although Dart gave up fossil hunting for some time, all was not lost. Years after the discovery of the "Taungs child", as it is known today, Dart and Broom found other Australopithecines at Kromdraii, Swartkrans and Makapansgat.

These finds of similar creatures seemed to vindicate Dart and Broom, and the scientific community again accepted their finds as they do today. These new fossil Australopithecines seemed to show two parallel lines of development, one being a small "gracile" slender type and the other a larger "robust" type.

Much controversy has existed regarding these types and some investigators, including Richard Leakey, have concluded that they represent merely the male and female of the same species while others say the gracile form, which is believed to be older, evolved into the robust form.

Today these animals are known as Australopithecus africanus and Australopithecus robustus respectively. The latter is clearly heavier, has more massive jaws, and a pronounced sagital crest.

All these traits are typical of sexual dimorphism in male apes. What is also felt to be a more human trait is that foramen magnum the opening in the skull above the attachment of the spinal column in Australopithecines seems to be placed in an intermediate forward position between that of modern apes and man.

Although not as far forward as in man, this more forward position is felt to indicate a more upright posture for the Australopithecines. The australopithecines have often been found in association with other animals, such as baboons, and often show evidence of bashed-in skulls. Tools in the form of clubs, knives, and choppers have been found in association, as well as evidence of fire.

It might be attractive to assume that the Australopithecines had been the hunters and butchers except that some of their skulls were broken in as well. Were they then the hunters or the hunted?

An American journalist met up with Dart who convinced him that the Australopithecines were actually hunting one another. The journalist, Robert Ardrey wrote a book, African Genesis, which popularized the view of the "killer ape.

Not bad for a primitive man who is still not yet walking completely upright and has a head the size of a chimp less than cc max. Although modern scientists do generally accept that Australopithecines had a generally upright gait and human-like posture, this notion has not gone uncontested.

Although evolutionists predictably discount Zuckerman's work, arguing that it is no longer accepted further discussion of such arguments a few paragraphs belowone must still at least consider the fact that in the s the famous British anatomist, Lord Solly Zuckerman, aggressively rejected the notion that Australopithecines are closely related to humans and completely discounted the notion that they walked upright like humans.From what I learned searching Amazon, the Pose Skeleton collection includes four human figures (each about three inches tall), some non-human (dinosaur and mammal) figures, and an assortment of accessories ranging from small items like baseball equipment to large room dioramas.

A cat's kidneys, like a human's, functions by filtering harmful and unneeded substances from the urine before it continues its path through the urinary tract.
