New discoveries in astronomy and biology continue to point to Panspermia as the most likely mode of the origin of life on Earth. This paper builds upon the work done by W.M. Napier, 2004 (), and re-estimates the time for the seeding of the galaxy given the latest 2013 estimates from the Kepler Mission data.

Haldane wrote a key paper on sex ratio and unisexual sterility in hybrid animals, where he showed that fertile xy progeny are unlikely (28). Collision of comets and asteroids onto the surfaces of inhabited planets like the earth could also result in the ejection and transference of genes belonging to evolved life-forms (e. Along with the water, comets also brought life.

Manning ce, mojzsis sj, harrison tm. As old world and new world camelids are some 10 12 million years apart, we can be fairly certain, through inference, that neanderthals were able to hybridize with humans from whom they had diverged by only a few hundred thousand years. Napier, 2004 ( ), and re-estimates the time for the seeding of the galaxy given the latest 2013 estimates from the kepler mission data.

Los angeles, california university of california press 2011. How is it possible that neanderthals and humans do not possess the same mtdna, yet share a small percentage of nuclear dna? This intriguing mix of findings leads us to contemplate the types of interbreeding that occurred between neanderthals and humans. Considering that neanderthals were robust and humans were in comparison gracile, male nean-derthals may have had according to haldanes law, the heterogametic offspring of interspecific hybrids are likely to be absent, rare or sterile (27).

We consider particles expulsed when the comet above reached the perihelion of its encounter with a star ( ). Calculations of this ratio for bacterial grains in the form of spherical clumps possessing thin outer skins of reduced carbon (graphite) for particles in the vicinity of the sun show that we have , the particles with pg 1 would be expelled from the entire solar system with an asymptotic velocity of 1 and m is the solar mass.

The financial instability hypothesis has both empirical and theoretical aspects. The readily observed empirical aspect is that, from time to time, capitalist economies exhibit inflations

Hypothesis Paper

Efficient-market hypothesis - Wikipedia
The efficient-market hypothesis (EMH) is a theory in financial economics that states that asset prices fully reflect all available information. A direct implication is that it is impossible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information.

This has been discussed recently by several authors in relation to impacts onto a life-laden planet such as the earth. It appears that many centuries of hybridization led to mosaic fossils with human cranial and dental features mixed with neanderthal body proportions. The early upper paleolithic human skeleton from the abrigo do lagar velho (portugal) and modern human emergence in iberia. If haldanes law applies to the progeny of neanderthals and humans then female hybrids would have been much commoner than male hybrids.

    Pestera cu oase 2 and the cranial morphology of early modern europeans. If haldanes law applies, few neanderthal y chromosomes would have survived. On such a picture, darwinian evolution will not be confined to a single planetary biosphere but would extend across a biosphere embracing the entire galaxy. In trounson ao, gosden rg, editors.

    If, for example, a species is subdivided into two subpopulations that become geographically separated, then the two groups may accumulate biological differences that reduce hybrid fertility. In a scenario previously not considered by other researchers (29), if male neanderthals mated with female humans, haldanes law would account for the apparent absence of neanderthal y-linked genes in the human population. Microorganisms expelled from comets in one planetary system can, under suitable conditions, reach other neighbouring planetary systems through the action of radiation pressure exerted by the light of the central star. Transfer of viable microbial life across such short distances under interstellar conditions would appear to be entirely feasible. Humans and neanderthals share a small percentage of nuclear dna, but they do not share the same type of mtdna. They stated historically, viruses have been mostly ignored in the field of astrobiology due to the view that they are not alive in the classical sense and if encountered would not present risk due to their host-specific nature. . This paper builds upon the work done by w. Chaotic exchange of solid material between planetary systems implications for lithopanspermia. A recent revision of the size of the habitable zones of stars, taking account of atmospheric greenhouse effects, has led to new estimates of the number of potentially habitable earth-sized planets around low mass stars in the galaxy as about n 10 (assumed to be a cylinder of radius 50,000 light year ly and thickness 1000 ly), this gives a mean spacing in the galaxy of (nv) the spacing could be even closer within the birth clusters of stars.

    The simulation hypothesis proposes that all of reality, including the earth and the universe, is in fact an artificial simulation, most likely a computer simulation.Some versions rely on the development of a simulated reality, a proposed technology that would seem realistic enough to convince its inhabitants the simulation was real.

    During the so-called hadean epoch of the earth, which involved heavy cometary bombardment, there is clear evidence of an excess of the lighter carbon isotope c indicating the action of microorganisms that preferentially take up the lighter isotope from the environment ( the hadean epoch in the earths geological history was undoubtedly marked by an exceptionally high frequency of comet and asteroid impacts Hypothesis Paper Buy now

    Extensive studies of the human genome (and other genomes) have shown the presence of viruses (mainly retroviruses) making up a large fraction of inert dna. Early modern humans from the pestera muierii, baia de fier, romania. Interbreeding between male neanderthals and female humans accounts for the presence of neanderthal nuclear dna, the scarcity of neanderthal y-linked genes, and the lack of neanderthal mtdna in modern human populations. Short-period comets, which live in the kuiper belt and have elliptical orbits in the plane of the solar system ecliptic longer-period comets, which can have elliptical orbits reaching out to the oort cloud (but it is the parabolic comets, which the writers believe have been involved in sling shot transfers from an adjacent star system) Buy Hypothesis Paper at a discount

    On such a picture, darwinian evolution will not be confined to a single planetary biosphere but would extend across a biosphere embracing the entire galaxy. The mtdna recovered from neanderthal fossils contains sequences not found in present-day humans. They recommended, that in our quest for extraterrestrial life, we should be looking for viruses and while any encountered may pose no risk, the possibility of an encounter with a virus capable of accessing multiple cell types exists. If haldanes law applies to neanderthals and humans, female offspring were more common.

    The high mutation rate of male sex-determining genes on the y chromosome may account for why nature rarely permits heterogametic offspring from interspecific hybrids (27). Although panspermia, and the hoyle-wickramasinghe model, as an overall hypothesis, could apply to not just our milky way galaxy but to the whole universe, the scope of the calculation, and thought experiment in this paper, is limited to the milky way galaxy. Comets and the origin of life. Our calculation is independent of the location of the point-source. The idea that neanderthals and humans were able to interbreed is not new (31), but the most recent data, coupled with an understanding of interspecific hybridity, allows us to conjecture that only male neanderthals were able to mate with female humans For Sale Hypothesis Paper
