All the continents have been mapped, cell phones are found in the most regions, and jet travel has made the world small indeed. There’s really nothing left to discover, right?
Wrong. It is estimated that fewer than half the Earth's species have been described.
In recent years, there have been amazing animals discovered around the world. Scientists have been celebrating the classifying of new species of animals discovered in deep oceans, tropical islands and other habitats in the world. The night blooming orchid, walking cactus, devil worm and yoda are some examples of newly found species by scientists.
The discovery of new species is an important part of conservation, since these newly discovered animals can't exist outside the natural world in which they developed. The identification of new species helps us better to understand and protect the habitats they occupy.
Field biologists are using interesting tools to analyze and classify new species. Based on a source on the internet, advanced microscopes can now be operated via remote control by scientists from thousands of miles away. DNA analysis allows specimens to be precisely identified. And online digital images of plants and animals allow wildlife experts in developing countries to access the same information that was once available only at prestigious and reputable universities.
Historically, animals have been used in a large range of scientific research activities that have provided many benefits to society, particularly to the advancement of scientific knowledge, medicines, and the safety of chemical substance.
Animal research falls under three broad categories: pure, applied and toxicology.
Pure research develops our knowledge and understanding of how human bodies work. Experimentation like this is called 'pure' research because it is exploratory. It is the nature of scientific discovery that not all experiments can be
