LifeÃ¢â‚¬â„¢s capabilities continue to astound. Another assumption of mainstream science is overturned: Now we find that some kinds of fungi can grow very nicely, thank you, in very high radiation environments, and even appear to thrive, using radiation as an energy source.
I wonder; in what sort of environment did these organisms evolve to account for this remarkable ability?
Ã¢â‚¬Å“Scientists have long assumed that fungi exist mainly to decompose matter into chemicals that other organisms can then use. But researchers at the Albert Einstein College of Medicine of Yeshiva University have found evidence that fungi possess a previously undiscovered talent with profound implications: the ability to use radioactivity as an energy source for making food and spurring their growth.
“The fungal kingdom comprises more species than any other plant or animal kingdom, so finding that they’re making food in addition to breaking it down means that Earth’s energeticsÃ¢â‚¬â€in particular, the amount of radiation energy being converted to biological energyÃ¢â‚¬â€may need to be recalculated,” says Dr. Arturo Casadevall, chair of microbiology & immunology at Einstein and senior author of the study, published May 23 in PLoS ONE.Ã¢â‚¬Â
It seems that certain fungi, specifically those containing melanin, the same stuff that give us those nice cancerous tans, thrive in high radiation environments. In their discussion the researchers note:
Ã¢â‚¬Å“The literature already contains some indirect evidence for the notion that radiation can enhance the growth of melanized microorganisms. For example, the melanotic fungus C. cladosporioides manifests radiotropism by growing in the direction of radioactive particles and this organism has become widely distributed in the areas surrounding Chernobyl since the nuclear accident in 1986 . Both in the laboratory and in the field several other species of melanized fungi grew towards soil particles contaminated with different radionuclides, gradually engulfing and destroying those particles , Ã¢â‚¬Â¦.
On the basis of these precedents and the results of this study we cautiously suggest that the ability of melanin to capture electromagnetic radiation combined with its remarkable oxidation-reduction properties may confer upon melanotic organisms the ability to harness radiation for metabolic energy.Ã¢â‚¬Â
It was observations in the aftermath of Chernobyl that led to this research:
Ã¢â‚¬Å“The research began five years ago when Dr. Casadevall read on the Web that a robot sent into the still-highly-radioactive damaged reactor at Chernobyl had returned with samples of black, melanin-rich fungi that were growing on the reactor’s walls.Ã¢â‚¬Â
The question naturally arises; whence came this unusual ability? Where in the evolutionary past of fungi are the Chernobyls or other high radiation environments? How will Darwinism explain the development of this surprising trait? Why ON EARTH would fungi need this ability?
Certainly for panspermia to work, there must exist organisms that can survive the rigors of space travel, including radiation. We already know about bacteria that can do this. Now we have another possibility.
And another difficulty for Darwinism.
