All ecosystems are dependent on both living and non-living parts. They also require energy, recycle matter, have ecological niche for each organism, has balance in populations of different species, and can be disrupted because of changes. […]
It is still not clear how the first organism came into existence. What is, is the fact that it started four billion years ago? Not having to compete for food or survival, it spread around the globe instantly. This also underlines the belief that we all have common ancestors. […]
The hydrothermal hypothesis posits that rocks and submarine hot springs could birth life and be its origin. This hypothesis also fathers the idea that, if true, life forms could be found on other planets and moons. […]
Miller and Urey tried to duplicate the ‘primordial soup’, thereby attempting to prove that that alone could possibly be how life originated on Earth. […]
Louis Pasteur discovered sterilization or pasteurization. Though not intentionally related to it, it had a bearing on the spontaneous generation of life theory. […]
In order to understand and discover how life actually originated on Earth, one has to account for what possible early life forms could exist in a primordial state. […]
Genetic modification in animals is easily accepted. However, when it comes to humans, it raises ethical questions such as should we alter our genetic makeup not only to rectify a defect but also to enhance our capabilities or make ourselves super human? […]
Cancer is an acquired genetic disease that occurs when cells lose the ability to die. Most of the time, regulatory processes orchestrate the death of cells that are defective. In cancer, the cells lose the ability to die. […]
Viral vectors are an effective way to reprogram cells to duplicate correct DNA and make a specific protein, the one that it should have been producing all along. […]
Because animals undergo an extremely complex process of cell differentiation, genetic approaches that work with bacteria don’t work with humans and animals. Thus, modifying human genes remains a challenge. […]
