Introduction to Human Evolution
Human evolution
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
One of the earliest defining human traits, bipedalism -- the ability to walk on two legs -- evolved over 4 million years ago. Other important human characteristics -- such as a large and complex brain, the ability to make and use tools, and the capacity for language -- developed more recently. Many advanced traits -- including complex symbolic expression, art, and elaborate cultural diversity -- emerged mainly during the past 100,000 years.
Humans are primates. Physical and genetic similarities show that the modern human species, Homo sapiens, has a very close relationship to another group of primate species, the apes. Humans and the great apes (large apes) of Africa - - chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas -- share a common ancestor that lived between 8 and 6 million years ago. Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa.
Most scientists currently recognize some 15 to 20 different species of early humans. Scientists do not all agree, however, about how these species are related or which ones simply died out. Many early human species -- certainly the majority of them – left no living descendants. Scientists also debate over how to identify and classify particular species of early humans, and about what factors influenced the evolution and extinction of each species.
Early humans first migrated out of Africa into Asia probably between 2 million and 1.8 million years ago. They entered Europe somewhat later, between 1.5 million and 1 million years. Species of modern humans populated many parts of the world much later. For instance, people first came to Australia probably within the past 60,000 years and to the Americas within the past 30,000 years or so. The beginnings of agriculture and the rise of the first civilizations occurred within the past 12,000 years.

The process of evolution
The process of evolution involves a series of natural changes that cause species (populations of different organisms) to arise, adapt to the environment, and become extinct. All species or organisms have originated through the process of biological evolution. In animals that reproduce sexually, including humans, the term species refers to a group whose adult members regularly interbreed, resulting in fertile offspring -- that is, offspring themselves capable of reproducing. Scientists classify each species with a unique, two-part scientific name. In this system, modern humans are classified as Homo sapiens.
Evolution occurs when there is change in the genetic material -- the chemical molecule, DNA -- which is inherited from the parents, and especially in the proportions of different genes in a population. Genes represent the segments of DNA that provide the chemical code for producing proteins. Information contained in the DNA can change by a process known as mutation. The way particular genes are expressed – that is, how they influence the body or behavior of an organism -- can also change. Genes affect how the body and behavior of an organism develop during its life, and this is why genetically inherited characteristics can influence the likelihood of an organism’s survival and reproduction.
Evolution does not change any single individual. Instead, it changes the inherited means of growth and development that typify a population (a group of individuals of the same species living in a particular habitat). Parents pass adaptive genetic changes to their offspring, and ultimately these changes become common throughout a population. As a result, the offspring inherit those genetic characteristics that enhance their chances of survival and ability to give birth, which may work well until the environment changes. Over time, genetic change can alter a species' overall way of life, such as what it eats, how it grows, and where it can live. Human evolution took place as new genetic variations in early ancestor populations favored new abilities to adapt to environmental change and so altered the human way of life.

How ‘Human’ Is This Newly Discovered Species?
Justin Worland @justinworland (Sept. 10, 2015)
The discovery of a new human-related species, named Homo naledi, has thrown the evolutionary biology world for a loop. The newfound species, uncovered in a South African cave system, appears to be an odd combination of primitive and modern features not previously seen together.
From the remains of at least 15 individuals, scientists assembled the skeletal system of Homo naledi and published the findings in the journal eLife. The new species has some remarkably human-like similarities, namely its hands and feet—though its brain is much smaller, as is its frame. Human hands have played a key role in the evolution of Homo sapiens, and that’s one of the similarities between humans and Homo naledi. Individuals of the Homo naledi species had opposable thumbs much like our own that would have allowed them dexterity somewhat like that of humans. The curved nature of the hands also suggests that the species may have had climbing abilities. Many of our close ancestors, including chimpanzees and apes, have opposable thumbs.
Perhaps the most significant similarity is not anatomical. Scientists say the cave location the Homo naledi remains were found appears to be a burial chamber. Burying the dead was a practice previously thought to be a unique human trait.
These similarities carry significance from an evolutionary perspective, but a number of traits make humans stand out from our predecessors. Human brains are typically between 1,100 and 1,200 cubic centimeters. Scientists estimated that the brain in Homo naledi would have been about half that size. Brain size isn’t everything when it comes to intelligent life and evolution, of course, but the structure of the brain in Homo naledi, revealed by the shape of the skull, also suggests a more primitive brain. Together, when comparing humans to a direct ancestor, the brain does suggest some distance between humans and Homo naledi.
The frame, including the shoulders and pelvis, also bears closer resemblance to early hominin species. Overall, scientists believe Homo naledi individuals weigh less than their human counterparts.
The differences between humans and Homo naledi are significant, but that doesn’t diminish the significance of the finding. The discovery of a human-related species just underscores how little we know about the life forms that preceded ours’ millions of years ago.
