Evolution: Extinction. The Story of Mankind. How did life originate? How did life originate?
Living things (even ancient organisms like bacteria) are enormously complex. However, all this complexity did not leap fully-formed from the primordial soup. Instead life almost certainly originated in a series of small steps, each building upon the complexity that evolved previously: Simple organic molecules were formed. Simple organic molecules, similar to the nucleotide shown below, are the building blocks of life and must have been involved in its origin. Multicellularity evolved.

Humans, apes, and monkeys are only distant evolutionary “cousins.” 2 There Are Too Many Gaps in the Fossil Record for Evolution to Be True In fact, there are lots of intermediate fossils. 3 If Evolution Happened Gradually Over Millions of Years Why Doesn’t the Fossil Record Show Gradual Change? Sudden changes in the fossil record are not missing evidence of gradualism; they are extant evidence of punctuation. 4 No One Has Ever Seen Evolution Happen Evolution is a historical science confirmed by the fact that so many independent lines of evidence converge to this single conclusion. 5 Science Claims That Evolution Happens by Random Chance Natural selection is not “random” nor does it operate by “chance.”

Photo by Greg Luna. 20 July 2010 — It's no secret to any dog-lover or cat-lover that humans have a special connection with animals. But in a new journal article and forthcoming book, paleoanthropologist Pat Shipman of Penn State University argues that this human-animal connection goes well beyond simple affection. Shipman proposes that the interdependency of ancestral humans with other animal species — "the animal connection" — played a crucial and beneficial role in human evolution over the last 2.6 million years.
"Establishing an intimate connection to other animals is unique and universal to our species," said Shipman, a professor of biological anthropology. Shipman suggests that the animal connection was prompted by the invention of stone tools 2.6-million years ago. . [ Kevin Stacey ] On Pangaea, latitude and rain dictated where species lived. PROVIDENCE, R.I.
[Brown University] — Aggregating nearly the entire landmass of Earth, Pangaea was a continent the likes our planet has not seen for the last 200 million years. Its size meant there was a lot of space for animals to roam, for there were few geographical barriers, such as mountains or ice caps, to contain them. Yet, strangely, animals confined themselves. Studying a transect of Pangaea stretching from about three degrees south to 26 degrees north (a long swath in the center of the continent covering tropical and semiarid temperate zones), a team of scientists led by Jessica Whiteside at Brown University has determined that reptiles, represented by a species called procolophonids, lived in one area, while mammals, represented by a precursor species called traversodont cynodonts, lived in another. Though similar in many ways, their paths evidently did not cross.
The scientists focused on an important physiological difference between the two: how they excrete. Chinese fossils shed light on evolutionary origin of animals from single-cell ancestors. Evidence of the single-celled ancestors of animals, dating from the interval in Earth's history just before multicellular animals appeared, has been discovered in 570 million-year-old rocks from South China by researchers from the University of Bristol, the Swedish Museum of Natural History, the Paul Scherrer Institut and the Chinese Academy of Geological Sciences.
All life evolved from a single-celled universal common ancestor, and at various times in Earth history, single-celled organisms threw their lot in with each other to become larger and multicellular, resulting, for instance, in the riotous diversity of animals. However, fossil evidence of these major evolutionary transitions is extremely rare. The researchers studied the microscopic fossils using high energy X-rays at the Swiss Light Source in Switzerland, revealing the organisation of the cells within their protective cyst walls. Do Humans Matter? New research may show that Neandertals did not go extinct. By Philip Guelpa 27 December 2011 The recently reported results of genetic research comparing samples of fossil Neanderthal DNA with that of modern populations around the world appear to indicate that modern humans outside of Africa derive some portion of their genetic material from Neanderthals. This finding, if supported by further research, has important implications, not only in answering the longstanding question of what happened to the Neanderthals, but more importantly for our understanding of the relative weight of cultural versus biological adaptation in human evolution.
Since the discovery of human-like fossils in the Neander Valley of German in the mid-19th century, anthropologists and others have debated the question of how closely Neanderthals, as this fossil group was named, were related to modern humans. The question soon became entangled in the larger issue of biological evolution in general after the publication of Darwin’s On the Origin of Species.
