Boesch & Boesche-Achermann found that this organization was key to a hunt's success -- when three or four chimps hunted, there was a success ratio of more than half. The chimps knew it, too; 92% of all the hunts the researchers observed were carried out in groups. Of those that were done in groups, 63% had some level of coordination. This statistic differs greatly from Jane Goodall's chimps at Gombe, who coordinated only 7% of their hunts. Boesch & Boesche-Achermann suggest that this contrast is of value to our understanding of human evolution; when a dramatic climate change struck Africa, east of the Rift Valley, it caused our ancestors to -- in adaptation to these new conditions -- develop cooperation in hunting. However, in Boesch & Boesche-Achermann's rainforest-dwelling chimps, we also see a high level of cooperation. Thus, we may need to rethink the timeline and setting of human evolution. Similarly, Boesch & Boesche-Achermann's...
Their evolutionary point-of-view dictates that they continually relate their findings to evolution and, specifically, that of humans. The article, as a whole, angled itself as surprising and revealing -- most of their key points' significance hinged upon the fact that they were in opposition to or considerably different from current evolutionary thought.
Evolution "Creational critics often charge that evolution cannot be tested, and therefore cannot be viewed as properly scientific subject at all. This claim is rhetorical nonsense" (Stephen Jay Gould). Human life is both sacred and mysterious. From time before recorded history, human beings, both scientific and religious have tried to determine what it is exactly that gives life and by extension, can take life away. In ancient times, most people believed that
EVOLUTION What is evolutionary theory and what are causes of evolution and the evidence of evolution? The term 'evolution' evokes varied connotations. In simple and direct terms it is a process of change or development over a long period of time. Defined so, evolution can refer to any phenomena-- evolution of universe, evolution of human culture etc. -- that change over a period of time. However, in common parlance, evolution refers to
Evolution vs. Creationism Biological evolution or evolutionary biology is genetic change in a population occurring from generation to another (O'Neill 2002). All life forms evolve and continue evolving from earlier species, and these life forms include human beings. Most biological scientists concur that the earliest life forms on earth evolved from chance natural occurrences 3 1/5 to 4 billion years ago. They agree that evidence for evolution comes from fossil records
Countless fossils and remnants of ancient limbs (such as the legs found on a dolphin recently) continue to back up the theory of how animals evolved from other forms of life and other kinds of bodies. For instance, whales and dolphins (proven by DNA to be related) have the vestiges of legs within their sleek bodies and their front "fins" have bones that correspond to human hands, rather than
In conclusion, perhaps we should heed the words of Charles Darwin himself who before his historic voyage aboard the H.M.S. Beagle between 1831 and 1836 was a devout Christian and creationist -- "There is a grandeur in this view of life. Whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and
For one, the researcher discovered that there was a structure called Meckel's cartilage that was present between the incus, or anvil bone, of the middle ear and the lower jawbone of Yanoconodon. Why is this so important? Well, coincidentally, in the developing human embryo the lower mandible transforms and produces the bones of the middle ear. As the embryo further evolves, the identical Meckel's cartilage is produced as the bones
