Synthetic antibiotic chemotherapy as a science and development of antibacterials began in Germany with Paul Ehrlich in the late 1880s. It was not until 1928 that Alexander Fleming observed antibiosis (The antagonistic association between an organism and the metabolic substances produced by another) against bacteria by a fungus of the genus Penicillium. Fleming postulated that the effect was mediated by an antibacterial compound named penicillin, and that its antibacterial properties could be exploited for chemotherapy. In 1939, coinciding with the start of World War II, Rene Dubos reported the discovery of the first naturally derived antibiotic, gramicidin from B. brevis. It was one of the first commercially manufactured antibiotics universally and very effectively used to treat wounds and ulcers during World War II. Antibiotics was a termed coined by Selman Waksman, an American microbiologist, in 1942. For their discovery and development of penicillin as a therapeutic drug, Ernst Chain, Howard Florey, and Alexander Fleming shared the 1945 Nobel Prize in Medicine.
The tank was well in use by the start of WWII. They were first developed by the French and British during the First World War.
The first gunpowder-powered rockets were developed in Song China, by the 13th century.
Sticks and stones have always been available for use as weapons. Either one could have been the first, but the stick may make more sense.
would involve the use of newly developed nuclear weapons
Thompson submachine gun was developed for use in World War I.
Never use any medication meant for humans on an animal without first consulting a veterinarian.
Unless it is medicine given to you by a vet, then no. Human medicine is made for humans. Cats are much smaller than humans, so giving a cat human medicine can easily lead to an overdose which can ultimately kill the cat. If your cat needs treatment, take it to a vet where they can prescribe medicine that is safe to use on your cat.

The first form of travel is believed to be by foot, where early humans walked to explore and find resources. This was followed by the use of animals for transportation such as horses, camels, and donkeys. Eventually, humans developed boats and rafts for travel over water.
Duramycin is an antibiotic used in veterinary medicine and is not approved for human use. It is important to consult a healthcare professional for appropriate treatment options if needed.
The first humans are believed to be part of the species Homo sapiens, which emerged in Africa around 300,000 years ago. These early humans were hunter-gatherers who had developed the ability to use tools and communicate with complex language.

This person's name has been lost to history, since humans and animals that produce fleece -- which is the base for wool -- have lived on Earth in a symbiotic relationship for ages. This event probably occurred before humans developed writing.

No, vetropolycin is specifically formulated for animals and should not be used on humans. It contains ingredients that are safe and effective for animals but may not be suitable for human use. It's important to use medications specifically designed for human use when treating medical conditions in humans.
The first humans used materials such as animal skins, furs, and leaves to make clothes. They would sew or tie these materials together to create garments for protection and warmth. Over time, humans developed more advanced techniques and started using different types of fabrics and fibers to make clothing.
