¶ … Alien Life on Earth
Scientists believe that all known life forms descended from a single common ancestor, a microbe that lived approximately 3.5 -- 3.8 billion years ago. Their belief is based on an understanding that all life forms have liquid water as their foundation, and they contain the same "building blocks" (Toomey 26). Researchers in the new field of synthetic biology have raised questions about another kind of living organism, independent of the building blocks already understood and unrelated to the last universal common ancestor (LUCA) from which all known life forms came. It is an intriguing idea that is attracting more interest as scientists continue to find evidence of this alien, or "weird" life on earth. The weird life is said to inhabit what is called the shadow biosphere.
Because little is known about weird life, scientists are considering myriad possibilities. The basic molecule might be other than DNA, for example, or its foundation might be ammonia, liquid methane or another substance besides water (Toomey). It is possible weird life exists in extremely inhospitable places, which would be one way of explaining why scientists know so little...

Search for Extraterrestrial Life: The Existence of Non-Human Intelligent Beings in Our Galaxy The possibility of extraterrestrial life has always intrigued philosophers, scientists, theologians and even lay people for centuries. The fascinating question of whether there are other intelligent creatures in space, however, remains unsolved despite technological advancements in science particularly because thus far, there still lacks conclusive evidence. Motivations for the search for non-human life range from scientific and philosophical
Since the Victorian era, science and scientists have been portrayed in dichotomous ways. Scientists are above all powerful, able to manipulate the natural world. Through their manipulations and machinations, scientists ironically disrupt the natural order of things, leading to ungodly inventions, abominations, or actual threats to human survival itself. The most notable examples of nefarious scientists in nineteenth century literature include Dr. Frankenstein and Dr. Jekyll. As the genre of
Is Ahimsa workable? The author on the one hand says that the Jains are ideal in respecting the sacredness of life but one the other hand they are too impractical. Even Gandhi himself claimed to follow ahimas yet he had to allow use of DDT to kill mosquitoes. Thus, the idea of ahimas is impractical for protecting lower species because they often kill too many people. Thus the workability of an
SPECIES Or, Men are from Earth, Women are from Venus Science fiction and speculative fiction have always enjoyed playing with popular conceptions of feminine roles. Speculative authors were among the first to bring us societies without sexual prejudices, and aliens who suffer role-reversals. Unfortunately, Sci-fi has also been a prime venue for enhanced machismo, and stereotypical treatments of women. Big-breasted space babes have always had their place in B-films. The film Species,
