Classification of living things
Aristotle, an ancient Greek philosopher, is considered the most incredible biological Discoverer. Classified the living things, which were revolutionaries. He referred to it as a ladder of life, and it was used up to the 19th century. He was the first person to recognise the relationship between the different species and organise them accordingly.
Early medical experimentation
Galen revolutionised Medical Research and its way of being conducted. He was a Greek physician who had significant influence in developing medicine, including Pathology, e anatomy, neurology, and Physiology. he discovered the identification of differences between arteries and veins and recognising that the voice is generated by the larynx
The contributions to the microscope are well known by Antonie van Leeuwenhoek and how he applied them to the field of Biology. The technique of creating powerful lenses was revolutionised by him, which can speculate the magnification up to 500 times. He discovered the living world through microscopes and discovered bacteria, a graphical of a cell and the Banded pattern of muscle fibres.
Physician, Zoologist, and botanist, Carl Linnaeus, came up with a system of ranking, naming and classifying organisms which we use today. His vast collection of animals, plants, and shells made him think to group and name this species. He separated the living things into three kingdoms, plants, animals, and Minerals and later subdivided them into classes.
Theory of evolution
Charles Darwin is one of the most famous naturalists of all time, and his contribution to society and Biology is immense. He discovered All the species are evolved from the same or a common ancestor. He was disputing the belief that God has created all the species at the beginning of the world. Still, the modern revolutionaries now accept the evolution by natural selection combined with the Genetics of Mendel.
George Mendel contributor extraordinary but didn’t get the recognition that he deserves until the death of the Friar. He used peas to demonstrate the laws of genetic inheritance and naming the term dominant and recessive genes in the process.
Barbara Mcclintock is an American geneticist who spent her career analysing maize, where identifying and examining chromosomes individually was the technique she developed. It is not immediately recognised but how work made it possible to locate the human genomes.
the DNA structure was discovered by James Watson and Francis Crick, for which they won the medical Nobel Prize. The model of DNA explains how it replicates, and genetic information is coded and passed.
Jane Goodall is the person because of whom our knowledge of wildlife and conservation has been transformed. She studied chimpanzees and discovered that the animals are all users and omnivorous.
Cloning a mammal
Ian Willmott and Kate Campbell cloned a mammal which is named Dolly, the Sheep. The cloned Dolly by using the process of nuclear transfer and a single adult shape cell. Dolly died after six years, but the cloning continued, although it was not perfect and not certainly ready for human application.
