... gene-manipulation- is scientifically called genetic engineering, which is the method of altering and manipulating organism's genetic or hereditary material to eliminate undesirable characteristics producing new desirable ones. It has been used in increasing the production plant and animal food, developing disease-resistant plants, diagnosing disease, improving medical treatments, and producing vaccines and other useful drugs. Although there is ... popular since after the Second World War, and is still used today. This method is most commonly for increased food production; only the plants...

... as single cells that reproduce themselves by similar division processes, whether they are a simple single-celled prokaryote or a complex organism with millions of millions cells. Specific characteristics from their parents by inheriting particular combinations of genes are received by all plants and animals. In fact, scientists have discovered that genes are segments of DNA molecules in ... occurs. However, not all organisms pass away. Fortunately, genetic diversity occurs throughout the natural populations. The plant or animal whose attributes allow them to endure an environmental disa...

... proposed, the most prominent theory on evolution was that of Jean Baptiste de Lamarck. Lamarck's theory has two parts: 1) the principle of use and disuse and, 2) the inheritance of acquired characteristics. The principle of use and disuse states that if an animal frequently uses an organ then that organ will grow in strength, and if an animal does not use an ... organ it deteriorates until it eventually disappears. The inheritance of acquired characteristics states that the changes that occur in animals through the principle of use and disuse are passed on to the animal's offspring. Lam...

Absolutely no transitional forms either in the fossil record or in modern animal and plant life have been found. All appear fully formed and complete.

... would be covered by the same progeny of a single pair. According to Darwin " in a state on nature almost every full-grown plant annually produces seeds and amongst the animals there are a very few which do not annually pair. In every plant and animal survive " it would rapidly stock every station in which they could anyhow exist. The Nature does its share, not ... organic being, these individuals will have the best chance of being preserved in the struggle for life. Possibly, those species will tend to produce offspring with the same or similar characteristics. This principal of preserv...
