Tulips are a popular flower grown in gardens all over the world. There are about 100 species of the genus Tulipa, native to many countries from Europe to Asia particularly in Austria and Italy eastward to Japan. Two thirds of the tulip species are also native to the eastern Mediterranean and the southeastern parts of the Soviet Union. In the 1500s tulips were introduced to the Western world by the Viennese ambassador to Turkey, Augier Ghislain de Busbecq, and from then on, they were cultivated as an industry in Europe.
Evolution, the theory proposed by Charles Darwin, refers to changes to the genetics of a species through mutations in genetic composition passed from generation to generation. These changes can be beneficial to the species and help them to adapt to changes in their habitat or to environmental stressors. Those species that adapt are more likely to survive and reproduce as they are more fit for the environment than other species.
In 2001 the human genome was completely coded. In 2005 the chimpanzee genome was coded. These two discoveries opened new areas of study in to how human and primate brains develop. MRI imaging has also brought about new studies in to the similarities and differences in brain structure between humans and our evolutionary ancestors. Ninety-eight percent of human and chimpanzee DNA is the same.
The brain is the most complex and sophisticated part of the human body. It is the body's "command center," processing nearly every type of task and action a person performs. Although the brain is made up of about 78 percent water, it also contains special cells known as neurons. Neurons can conduct small electrical impulses to send and receive information to and from each other. The brain is also divided into four major sections, with each section having a specific function.
You find a glass of lemonade on a picnic table and drink it. Two hours later, you're sick, with a fever and a headache. You then ask yourself if the glass of pink lemonade you drank was the cause of your sickness. Though you might not realize it, your question is an investigation into correlation and causation. Before you can continue this investigation, you must be able to distinguish between correlation and causation.
Apes, humanity's closest relatives in the animal kingdom, can walk, use tools and communicate signals in the same way that humans can. According to Dr. Daniel Geschwind, a distinguished professor of human genetics at the David Geffen School of Medicine, more than 95 percent of humanity's genetic make up is also represented in chimps' genetic code. The key factors that set you apart from one of these hairy friends is the size, and more importantly, the functions of your brain.
Long the butt of jokes in popular culture, the "Neanderthal" was an ancient species of hominid in the genus "homo" --- the same as our own. From around half a million years ago up to around 30,000 years ago, Homo sapiens shared the planet with Neanderthals. Although they looked relatively similar, and probably interbred to some degree or another, Neanderthals and modern human beings were different in a number of key ways, including variations in diet, geographic range and behavior.
The gangly, heavy-bodied spider monkeys of the tropical Americas are among the most distinctive of primates, fully adapted to an entirely arboreal life of supreme canopy mobility and maneuverability. Their taxonomy suggests the diversity of that tantalizing order of mammals, the primates, which range from tiny, insect-eating bush babies to massive 500-lb. gorillas.
While dogs do have individual personalities, they also have a number of behaviors that are determined by their genes. It is important to be aware of these behaviors, as they define a number of things about how your dog interacts with you, other dogs and the world around him.
Humans and chimps have genomes that are 96 percent the same. This makes sense, because they are our closest living relative. However, within the 4 percent of our genome that is not shared lies the DNA for our starkly different appearances. An example of this can be found in the differences between human and chimp skulls. Though they have definite similarities, as do all skulls, there are some clear differences.
In most taxonomies, modern humans are placed in the family "Hominidae" along with the great apes: gorillas, orangutans, chimpanzees and bonobos. Given that humans and chimpanzees share around 98 percent of their genomes, it is not unexpected that, at first glance, their skulls might look fairly similar to the untrained eye. However, there are number of traits to look for that will help you tell the difference.
Primates are the group of mammals comprising of humans, apes, monkeys and prosimians such as lemurs and bush babies. Some communicative behaviors are common between all or some of these species. Of most relevance to human behavior are those observed amongst the great apes, which, of all the members of the animal kingdom, are our evolutionarily closest relatives.
According to current scientific theory, life arose from inanimate matter about 3.7 billion years ago, about a billion years after the earth formed. It is thought human evolution separated from that of the apes -- our closest relatives -- in the last 10 million years. This means apes and humans share a lot of ancestors -- over 3 billion years of them. Most of these ancestors resembled neither humans nor apes.
Chimpanzees share 98 percent of the genetic material human beings have. These mid-sized apes (Pan troglodytes) usually walk on their knuckles, though on occasion they stand and walk upright as humans do. Though habitat destruction has greatly decreased chimpanzee numbers and landed the animals on the endangered species list, the primates live in 20 or 21 countries through central, western and northwestern coastal Africa in a handful of habitat types.
Chimpanzees are our closest relatives in the animal kingdom. Both the common chimpanzee and the more slender bonobo, both native to equatorial Africa, share most of our genetic makeup and demonstrate similar behavioral tendencies for excitability, ingenuity and, particularly in the case of common chimps, warmongering and violence. While they are the smallest of the great apes, chimps carry themselves confidently in the forests and savannas they call home thanks to a suite of innate survival tools at their disposal.
"Juvenile" is a general term used to describe a young animal. A juvenile is in transition from infancy to adulthood, and may display characteristics of both stages. In chimpanzees, the juvenile is sometimes defined as one who is sexually immature but can get its own food and otherwise survive the loss of a parent or caretaker through death or abandonment.
A cell wall surrounds the cell membrane and gives support to cells. The cell wall helps control moisture loss from the cell and protects the cell from outside forces. Scientists can classify whether a cell wall is from a plant, alga, fungus or bacterium because the composition of the walls varies among these organisms.
The term "silverback ape" refers not to a distinct species, but rather to a type of great ape of particular age and sex -- specifically, an adult male gorilla. Often it even more acutely describes a dominant male, leader and defender of an extended family group. These magnificent animals, threatened with the rest of their kind by habitat loss, poaching and human strife, are the largest and burliest of primates.
As we learn more about the human genome, we can connect more human traits to particular genes. Researchers interested in investigating genes associated with criminal behavior face several challenges related to the complex nature of the cause of any type of behavior. There are also social and political implications associated with identifying certain people as being prone to criminal behavior based solely on their DNA.
All mammals' brains share the same basic structure. This structure essentially consists of a cortex that lies above the cerebellum. The brain stem in both humans and chimps lies just above the spinal cord.
Children are naturally curious, and chimpanzees--whose expressive faces and social behavior make them seem so much like humans--naturally arouse children's curiosity. Native to the African continent, this endangered species has disappeared in areas where it once thrived, such as Gambia, Benin and Burkina Faso. According to the World Wide Fund for Nature (WWF), deforestation and commercial bushmeat hunting practices are devastating the chimpanzee population. Children who learn to love these fascinating animals may grow to be adults who take an active role in saving them from extinction.
Two species of chimpanzees inhabit the forests of Africa. Common chimps live mainly in parts of western and central Africa. Pygmy or dwarf chimps, also known as bonobos, inhabit the Congo Basin in central Africa. Common chimp and bonobo populations have declined significantly since the 1970s, according to the International Union for Conservation of Nature. Rapid human population growth has increased the severity and number of threats affecting both species.
Chimpanzees (Pan troglodytes) have a taxonomic classification that contains many subdivisions and has increasingly come under debate. Like all animals they belong to the kingdom Animalia, and as vertebrates (they have a backbone) to the phylum Chordata. They are warm-bloodied animals with fur, so they are part of the class Mammalia and as simians they belong to the order Primates. They have a distinct taxonomic system within this order. Taxonomic groups are based on similarities in DNA.
Chimpanzees are known scientifically as Pan troglodytes and they are a type of great ape. They are native to Africa and are members of the Hominidae family, which includes orangutans, gorillas and humans. Learning more about chimpanzees' reproduction sheds some light on their habits and way of life.
Chimpanzees, or Pan troglodytes, are the apes most closely related to humans. That means we study them to learn about ourselves, behavior and to test foods and medications. However, while they continue to help our scientific progress, their natural habitat quickly disappears. Called "sokwe mtu" in Swahili, chimps move to new habitats to continue to survive.
Chimpanzees are a close cousin to humans and share many of the same general characteristics. Because they still survive in the wild, though, without benefit of civilization, chimps have retained many of the adaptations that humans have lost.
Chimpanzees have a number of adaptations that help them to survive and succeed in their natural environment. Chimpanzees are native to many east and central African countries, including Cameroon, Democratic Republic of Congo and Uganda. Within these countries, chimpanzees live in forests and their many adaptations reflect their arboreal lifestyle.
Chimpanzees have a gentle reputation but can be aggressive and dangerous wild animals. They will defend themselves and their young from potential predators, people, or other chimpanzees. A chimpanzee will use different methods of defense depending on the threat it faces. The level of aggression will increase as the chimpanzee feels more and more threatened.
Chimpanzees are the closest living primates to human beings, with a remarkable 98 percent similarity in DNA. They are listed as an endangered species. There are fewer than an estimated 100,000 chimpanzees residing in the wild, and constant destruction of their habitat, hunting and being traded on the black market continues to reduce their population.
Science tells us that chimpanzees are the closest cousin to humanity, sharing much of our DNA and many physical and personality traits. Chimps are smaller than humans at 4 feet and 90 to 120 lbs., but have many of the same needs. Their habitats across the world reflect those needs.
Most people are only able to view chimpanzees in a zoo or other man-made environment. But you may have wondered about the chimpanzees' natural habitat. Where they live, what conditions they prefer and how they survive may be some of the questions you'd like answered.
Chimpanzees and bonobos, considered man's closest living animal relatives, are powerful primates--a physical trait apparent to anyone who's ever seen a chimp swing through a forest canopy or hurl rocks in dominance displays.
Primates such as great apes and monkeys bear many physical, behavioral and genetic similarities to humans. However, distinct differences in the brain have contributed to humans' evolutionary leap forward.
Chimpanzees have long been discussed as being the mammal most closely resembling the biological characteristics of humanity, spawning theories that chimpanzees may have a common ancestor with humans. These colorful primates have long been fascinating to mankind, as they are stunningly similar to us in how they interact with other chimpanzees, as well as their physical traits and behaviors.
Chimpanzees hold a fascination for most people, since they seem so close to being human that we can easily relate to them. One area of particular interest to researchers is the rearing and nurturing of babies within the chimpanzee society. In-depth studies are ongoing to learn how maternal care of offspring affects the future of that offspring. Researchers envision that this may give us insight into how our own parenting affects children. What is known about chimpanzee nurturing methods is that the mothers take their nurturing role seriously, balancing tender care with teaching necessary life skills.
Humans and chimpanzees are closely related in the animal kingdom, with scientists estimating we share 99% of our DNA with chimps. This similarity can be seen in some human/chimpanzee brain functions. But in other functions, evolution and genetics account for vast differences.
Chimpanzees are primates from the family of great apes, which includes gorillas and orangutans. The closest living relative of humans, chimps are highly intelligent and very easily trained.
