Dimi Chakalov said: "... 1. 2. 3. 4. 5. 6. My thoughts are: It looks to me as though "re-annealing" (in 2) = "collapse" (in 5 and 6). In the Many-Worlds picture of the Multiverse Macrospace, you don't have collapse, but what happens is that you cease to experience ALL AT ONCE many superposed possibilities and you begin to experience EACH possibility IN ITS OWN "world" with no (or very limited) connections among the different "worlds". Robert Neil Boyd has suggested that Consciousness could be modeled by Clifford algebras.
Epigenetics: A Turning Point in Our Understanding of Heredity | Guest Blog. In a study published in late 2011 in Nature, Stanford University geneticist Anne Brunet and colleagues described a series of experiments that caused nematodes raised under the same environmental conditions to experience dramatically different lifespans. Some individuals were exceptionally long-lived, and their descendants, through three generations, also enjoyed long lives. Clearly, the longevity advantage was inherited.
And yet, the worms, both short- and long-lived, were genetically identical. This type of finding—an inherited difference that cannot be explained by variations in genes themselves—has become increasingly common, in part because scientists now know that genes are not the only authors of inheritance. There are ghostwriters, too. Epigenetics and the state of chromatin In Brunet's lab, epigenetic inheritance is a big deal. Chromatin is a compact fiber of proteins and DNA that exists in either a condensed or a relaxed state. Epigenetic inheritance of longevity in nematodes.
Current Biology. Human Evolution Timeline. 7 Eye-popping interactive timelines (and 3 ways to create one) Eye Evolution - Cumulative Evolution of Complex Structures - Science 8 - Childs. Directions: The diagram at right shows the evolution of the eye. One of the criticisms about evolution is that complex structures (such as eyes) could not evolve randomly, as is the case with natural selection. However, CUMULATIVE EVOLUTION explains how natural selection of random variations within a species could produce complex structures.
An eye does not just appear one generation in a species, it is a slow process of slightly better adaptations that over long periods leads to the development of the eye. Cumulative evolution happens step by step - not all at once. Well adapted organisms take generations for the random forces of natural selection to select for more advantageous traits.

Natural Selection The characteristics of birds result from evolutionary processes, the most important process being natural selection. It was Charles Darwin who first pointed out that just as stockmen shaped their herds by selecting which animals would be allowed to breed, so too nature shaped all organisms by "selecting" the progenitors of the next generation. Darwin's thinking had been influenced by the great economist Thomas Malthus, who emphasized the capacity of people and other organisms to multiply their numbers much more rapidly than their means of subsistence. Darwin realized, therefore, that most individuals born of any species could not have survived long enough to reproduce.
Darwin knew nothing about genetics; the work of Gregor Mendel remained undiscovered until early in this century -- almost 50 years after the publication of Origin of Species. Natural selection provides a context in which to view the physical and behavioral characteristics of birds. Research reveals genetic link to human intelligence. University of Manchester scientists, working with colleagues in Edinburgh and Australia, have provided the first direct biological evidence for a genetic contribution to people's intelligence. Previous studies on twins and adopted people suggested that there is a substantial genetic contribution to thinking skills, but this new study -- published in the journal Molecular Psychiatry -- is the first to find a genetic contribution by testing people's DNA for genetic variations.
The team studied two types of intelligence in more than 3,500 people from Edinburgh, Aberdeen, Newcastle and Manchester. The paper, by Dr Neil Pendleton and colleagues, found that 40% to 50% of people's differences in these abilities could be traced to genetic differences. The study examined more than half a million genetic markers on every person in the study. The new findings were made possible using a new type of analysis invented by Professor Peter Visscher and colleagues in Brisbane. Epigenomics Fact Sheet. Cancers are caused by changes in the genome, the epigenome, or both. Changes in the epigenome can switch on or off genes involved in cell growth or the immune response. These changes can lead to uncontrolled growth, a hallmark of cancer, or to a failure of the immune system to destroy tumors.
In a type of brain tumor called glioblastoma, doctors have had some success in treating patients with the drug temozolomide, which kills cancer cells by adding methyl groups to DNA. In some cases, methylation has a welcome secondary effect: it blocks a gene that counteracts temozolomide. Changes in the epigenome also can activate growth-promoting genes in stomach cancer, colon cancer and the most common type of kidney cancer.
