misconception that evolution occurs randomly. This misunderstanding incorrectly assumes that natural selections itself is random. However‚ even though randomness plays a part in the process of evolution through genetic mutations‚ it does not necessarily stipulate that species evolve without cause. Genetic variation occurs randomly and is determined by the fitness and success of a species. It is directly related to its inherited traits with the context of its local environment. The mechanism of evolution controls

According to the World Health Organization‚ genetically modified food (GM food) are food derived from organisms whose genetic material has been modified in a way that does not occur naturally‚ such as through the introduction of a gene from a different organism. GM food‚ which stem mostly from plants‚ are genetically modified to develop a better yield by turning it resistant to plant diseases or tolerant to herbicides. The discovery of GM food has influenced the society in different ways and GM foods

It is becoming really difficult to feed the world. Because of population growth humans are going to have to use space and resources efficiently to be able to feed everybody on the planet. People are trying to genetically modify foods so that the food uses less space‚ water and resources. While being able to feed the world the food has to be also healthy and nutritious. Soybeans are advanced in the field of genetic modifications. In 2007 58.6 % over one half of the world’s soybean crop was genetically

’Genetically modified Products: Harmful or Helpful? Genetic‚ modification in products is not a new concept‚ for many years‚ scientist have been doing research in this field‚ consequently there have been a lot of discussion on whether genetic modification of a product is bad or good. Genetic modification was limited to mixing traits of organisms only within the same family of species‚ but due to advanced biotechnology‚ scientist can now genetically modify different species. Genetically engineered

Genetic engineering is the human’s control into an organism’s genetic make-up by alteration of the genetic content such as the DNA of humans‚ which does not occur in natural conditions. Various techniques are used to prepare recombined parts of DNA from other organisms back to the origin. Genetic engineering is a type of selective breeding. Genetic Modification is very controversial. Individuals have their own personal beliefs regarding this field of research. There are great benefits to genetic

most of the time we forget that money will not prevent us from catching a disease‚ it maybe help you pay for the best treatment‚ but if there is no cure‚ then it is too late. So to me focusing on the development of sectors related to medicine and human biology is way more important than producing the next iPhone‚ not that these gadgets aren’t unique and important‚ but this is the only way at these point to alter the effects of globalization‚ I do not think it can be contained unless we go back to

Throughout the course of human history‚ hunters-gatherers remained their existences in every stage of evolution as they are the fundamental response units when it comes to food. By the region or area different hunters-gatherers occupied‚ different food source or species of food were limited by the set boundary of each tribe. Oftentimes hunters-gatherers equipped with advanced technology at their time to lower the amount of energy needed to lay their hand on their prey. Bow for example is a piece

GENETIC ENGINEERING IS BENEFICIAL TO MANKIND We‚ Homo sapiens (and every other organism on the planet)‚ become what we are on the basis of the genes we inherit from our parents at the time of our birth. Whether you are tall‚ short‚ dark‚ dusky or fair‚ have great hair‚ good health - everything depends on these genes. Earlier these genes were believed to be ’tamper proof’ and they could not be manipulated. But the human brain and contemporary science does not deem anything as impossible. Thus

Are genetically modified foods beneficial? Frederick J Cole Genetically modified foods are produced from plants which have had their genetic make-up ‘tweaked’ in the lab. Scientists “cut and paste” a gene from another organism into a plant’s DNA to give it a new characteristic. I have always been interested in Biology and I have heard a lot of bad things about GM food‚ but I have always wondered if there are any benefits‚ so this is what I would like to research. Firstly‚ I would like to look at

genetically engineered food and distributing to the public without the publics knowledge is unethical. Another ethical issue is not knowing what side affects of the engineered food will do to humans in the long term. It is still not determined whether or not some of these GM foods will cause health problems in humans in the long run and should be tested like new drug have to be tested. It seems to me that the government is not as strict on GM foods like they are on new drugs being tested. 2) Do you
