He also found out that giraffes live in the interior of Africa where the soil is dry, so they can feed on trees (Holdrege para. 3). Charles Darwin made an adjustment on the evolution of giraffes sixty years later (Holdrege para. 5). Charles Darwin thought that the giraffe have long legs, neck, and tongue to eat off of higher branches in trees (Holdrege para.
As plant eaters, sauropods were adapted with very long necks. Mamenchisaurus had the longest neck which was about 50 feet long, more than half of its body length (Thomas, 2011). The neck length also varied from one sauropod to another. Sauropods such as Sauroposeidon and Brachiosaurus (the Brachiosaurids) had necks that were vertically positioned like that of the giraffe. In addition, other sauropods had necks that were horizontal-like and parallel to the ground.
Giraffes feed highly in the first and last hours of daytime, between these hours, giraffes stand and ruminate. At night giraffes lie ... ... middle of paper ... ... the males are and after the fight ends the victor will mount the losing male to claim its victory and attract females for reproduction. Conclusion In conclusion the giraffe is one of the most majestic creatures on earth, they are known to be unique and many people are fascinated by the height and beauty of this creature. It lives among the giraffe family and communicate with other giraffes to detect danger, tend to its young and reproduce. It is strong and not usually targeted by predators because it can detect danger easily and can gallop fast enough to get away from danger.
A typical giraffe has about 2 or 5 horns on its head. A female usually has hairy ossicones while the male has bald ossicones (Nazir, 2013; Mccarthy, 2013). In weight distinctions, a male usually weighs about 3,500 pounds while the female weighs about 1,800 pounds. Similarly, most giraffes have a fur coat. The common fur color is yellow and black, but it could change as the season changes.
That's when two scientists, Robert Simmons and Lou Scheepers made the claim that necks evolved for a very different reason: sexual selection. Within this paper, information will be presented that argues both for and against the theories made by Darwin and Simmons and Scheepers. Giraffes are placed in the family, Giraffidae, separate from other animals such as the camel, deer, and cow. Typically, giraffes are about 19 feet tall and can weigh as much as 4000 pounds. The evolution of modern giraffes began about 1 million years ago from a similar species known as Giraffa jumae.
This four-winged dinosaur has fueled debate over evolution of airborne birds. This subject has re ignited debate over and over again about the origins of birds including feathers and their flights. The researchers believe that this bird has been around for about 124 to about 145 million years. Researchers also believe that these birdlike animals belong to a new species called Microraptor gui, a stem from the previous species Microraptor. The discovery of the fossil was found in the beds of Liaoning Province of the northeast China.
Peafowls along with turkeys, pheasants, and quail are all commonly known to be Galiformes that are in the Phasianidae family. The Genus name of all peafowls is Pavo which translates into peafowl. The species name for these birds are the Pavo Cristatus which again, means peafowl and crested. The common name for this bird is the Indian Blue Peafowl (Indian Peafowl, 2011.) These Indian Blue peafowls are one of the most amazing birds around the world, there are many interesting physical traits, habitats, and facts about these peafowls.
Several kinds of baboons live in Africa and southwestern Arabia. These include the hamadryas baboon, which lives on plains and rocky hills of Saudi Arabia, Yemen, and eastern Africa near the Red Sea, and the chacma baboon, which inhabits rocky regions and open woodlands in southern Africa. Olive baboons inhabit the Kekopey cattle ranch located near the town of Gilgil, Kenya. “The central part of the ranch consists of open grassland studded with occasional patches of bushy shrub, scattered thornbush, and small groves of giant fever trees” (Smuts 17). They eat a wide variety of foods including insects, flowers, leaves, fruits of bushes and herbs, and most significant of all, the grass itself.
This is important because it allows grasses to grow, which provide food for many other animals on the grassy plains. Black rhinos travel alone except while breeding or raising offspring. Juveniles remain with the mother until they are completely weaned, just before a new a baby is born. Young rhinos are occasionally prey for many items for large carnivores such as lions and hyenas. People of some cultures believe that rhino horns contain medicinal properties.
Due to their close evolutionary relationship to humans, chimpanzees and bonobos have been widely studied and used as models for the behavior of early hominids. In recent years, new information regarding the social behaviors and ecology of bonobos has come to light, and this has warranted many interspecific comparisons between bonobos and chimpanzees: “Chimpanzees have been characterized in terms of their intercommunity warfare, meat eating, infanticide, cannibalism, male status-striving, and dominance over females. Bonobos, meanwhile, have been portrayed as the ‘Make love, not war’ ape, characterized by female power-sharing, a lack of aggression between either individuals or groups, richly elaborated sexual behavior that occurs without the constraint of a narrow window of fertility, and the use of sex for communicative purposes” (Stanford 399). Over the course of this paper, I will provide evidence for the dichotomy between these two species, with particular attention to the histories of their research, the nature of their social interactions, as well as their sexual behaviors. Molecular studies indicate that humans, chimpanzees, and bonobos are very closely related in terms of their lineage, which split into hominid and Pan lines about 6-7 million years ago.
