"The human species is about evolution and is about moving forward, " said Eric Anderson, president of Space Adventures Ltd.
That was because his hypothesis was that if linguistic evolution is jerky, the jerks will happen at the points where languages split the equivalent of species splits in biological evolution.

Using informed but clear language, she guides the reader through Darwin's own encounters with giant tortoises, iguanas and finches on these islands in the 1830s that led him, years later, to formulate his theories about the origin and evolution of species.
For him, the process of evolution involved new species gaining ground and others losing out.
However, another less observed species can also shape the evolution of innovation in unexpected and sometimes important ways.

He did indeed develop a theory that species evolve and that the two crucial conditions of evolution were time and favourable conditions, in other words that species adapt to their environment.
Darwin's theory of evolution predicts how different species evolve.
Prof Ian Tattersall said there were few examples to rival the accelerated evolution that led to our species.

He landed, camped there, left and returned, studied, researched and conceived his earth-shaking theory of evolution, On the Origin of Species, in 1859.
These findings would not have surprised Charles Darwin, who in addition to theorizing on evolution in The Origin of the Species, also developed the Facial Feedback Response Theory, which suggests that the act of smiling actually makes us feel better (rather than smiling being merely a result of feeling good).
Extinction is the norm in evolution: the vast majority of all species have gone extinct.
Its evolution is producing an extraordinary variety of species.
True, we have a lot more choices (often aided by technology) about precisely how we do these things in the modern world but we are still built by a hundred thousand years or so of our own species, tens of millions of years of mammalian evolution, into ending up with slightly different brains and slightly different interests to go along with our very different gonads.
These mutations didn't affect health until long after the individual had fulfilled his or her role in propagating the species, so they were more or less ignored by evolution.

These curious hominids lived about two million years ago in an era that scientists consider the crucible of human evolution, when four or more apelike hominid species struggled for survival in Africa.
Other texts appearing online for the first time include the first editions of the Journal Of Researches (1839), The Descent Of Man (1871), The Zoology Of The Voyage Of HMS Beagle (1838-43) and the 2nd, 3rd, 4th and 5th editions of the Origin Of Species, the pivotal tome that elucidated his thoughts on evolution.

Evolution as fact refers to the historical reality that species are related through common ancestry.
By analysing where these differences occur in the animals' genomes, it is possible to get an insight into the two species' histories - the timing of key events in their evolution.

That many human genes originated in much older species was something many biologists had long suspected, based on Darwinian evolution.
Or that the mixing of genes between unrelated species is no more unnatural than the gene flows that have driven evolution since life began.
FORBES: 'I Was Wrong:' How One Activist's Apology Changes the GMO Debate
Robin Dunbar, an anthropologist at the University of Liverpool, has studied primates and discovered a surprisingly stable ratio between the relative size of the neocortex (thought to be responsible for the evolution of intelligence) and the size of groups formed by particular species.
ECONOMIST: Blogging is just another word for having conversations
This dynamic can be seen not just in economic life but in the evolution of all things, from cuisine, urbanization and legal systems to our own existence as a species on this planet.
FORBES: Will Big Data Make Your IT Organization Antifragile?
Dr Hazen and his team speculate from meteorite and early rock studies that several hundred mineral species, including zircon, quartz, clay and halite salt crystals, formed during this early period of mineral evolution.
