Fransesco Redi compared two competing ideas to explain why maggots appear on rotting meat. He observes that meat covered to exclude flies does not develop maggots, while uncovered meat did. This is the first use of a controlled experim
A controlled experiment will lead to better planned and tested experiments in the future. An experiment isn't too helpful when there is no standard to compare it with. -
Scientists successfully create a recombinant organism for the first time.
The recombinant organisms will be required in order to genetically modify things and create vaccines. -
The firm, Genetic Science, injects genetically-modified microbes into trees.
This experiment is going to give scientists a way to effectively modify plants in whatever way they want with genetically modified microbes . -
The US Enviromental Protection authority approves the release of the first GM virus resistant tobacco plant.
This is going to encourage others to genetically modify their tobacco plants to be virus resistant too. -
The first genetically engineered food product, the FlavrSavr tomato, recieves the US food and Drug Administration approval.
Genetically engineered foods are now approved in the US, though there is usually no indication that it is modified. -
Researchers at Scotland's Roslin Institute clone a sheep named Dolly.
Cloning is now a process that is possible. If they can clone a sheep, then it would be no problem cloning specific genes, namely in food. -
Researchers sequence the DNA of rice, the main food source for two-thirds of the world's population. It is the first crop plant to have its genome decoded.
Even though rice is eaten by two-thirds of the world's population, it is being modified without the consent/knowledge of the people. -
Australian researchers use gene mapping techniques to identify genes for tenderness and toughness in beef.
It is now expected by consumers that the beef is more tender than tough. With this, the standard rises and the people will soon want other foods to be "better" than the average. -
US researchers identify a gene that increases the protein, iron, and zinc content of wheat kernels.
Wheat kernels can now have their amount of protein, zinc, or iron increased, leading to some people craving even more healthier foods. -
Producers are required to label foods if they are modified in any way.
A law will be passed for this because people generally would not want to eat something they do not know. -
Scientists are able to modify crops to be able to grow without farmland or soil.
With this, what was previously farmland can be cities and houses for our growing population.
