Ancient Greek philosopher Aristotle isn't often considered when it comes to great biological discoveries, but his work on the classification of living things was revolutionary. Referred to as the 'Ladder of Life', Aristotle's classification system was used up until the 19th century.

He was the first person to recognise the relationships between species, and organise accordingly. The work of Greek physician Galen revolutionised the way medical research is conducted. Galen had a major influence on the development of many fields of medicine including anatomy, pathology, physiology and neurology. Notable discoveries include the identification of the differences between veins and arteries, and recognising that the larynx generates voice.

Much of his hypotheses had scientific errors but his work in pioneering the field of medical research is undeniable. Antonie van Leeuwenhoek is well known for his contributions to microscopy and how he applied this to the field of biology. He revolutionised a technique for creating powerful lenses, which some speculate were able to magnify up to times. Leeuwenhoek used the microscopes to find out more about the living world — his discoveries include bacteria, the vacuole of the cell and the banded pattern of muscle fibres.

A botanist, physician and zoologist, Carl Linnaeus came up with the system of naming, ranking and classifying organisms we still use today.

It was his vast collection of specimens of plants, animals and shells that led him to think up a way of grouping and naming species. He separated all living things into three kingdoms — animals, plants and minerals — subdivided them into classes, then into orders and finally into genera and species.

Gregor Mendel's extraordinary contribution didn't get the recognition it deserved until long after the friar's death. The laws were rediscovered at the turn of the 20th century and provided the mechanism for Darwin's theory of natural selection to occur. The two theories combine to form our current understanding of the evolutionary process.

American geneticist Barbara McClintock spent her career analysing maize, where she developed a technique for identifying and examining chromosomes individually.

Despite it not being immediately recognised, her work made it possible for us to map human genomes. She was awarded the Nobel Peace Prize in for her discovery of transposition and how genes could turn their physical characteristics on and off. The discovery of structure has led to a much more developed understanding of function — used in disease diagnosis and treatment, forensics and more.

Our knowledge of wildlife and conservation has been transformed by Jane Goodall, the UK ethologist. Best known for her career-long studies of chimpanzees, she discovered the animals are omnivores and tool users. The pair cloned Dolly using a single adult sheep cell and a process of nuclear transfer.

Dolly died after six years but cloning continues, although still not perfected and certainly not ready for human application yet. Missed the January deadline for undergraduate applications?

Aristotle — BC : classification of living things Ancient Greek philosopher Aristotle isn't often considered when it comes to great biological discoveries, but his work on the classification of living things was revolutionary.

Galen — AD : early medical experimentation The work of Greek physician Galen revolutionised the way medical research is conducted. Antonie van Leeuwenhoek — : microbiology Antonie van Leeuwenhoek is well known for his contributions to microscopy and how he applied this to the field of biology.

Carl Linnaeus — : modern taxonomy A botanist, physician and zoologist, Carl Linnaeus came up with the system of naming, ranking and classifying organisms we still use today. Charles Darwin — : theory of evolution Probably the most famous naturalist of all time, Charles Darwin's contribution to biology and society is immense. He established that all species of life descended over time from common ancestors, with species continuing to exist through the process of natural selection.

His theory of evolution was published in On the Origin of Species in and it caused quite the stir — he was disputing the long-held belief that all species had been created by God at the beginning of the world. Evolution by natural selection combined with Mendelian genetics is now accepted as the modern evolutionary synthesis and forms the foundations of much biological scientific endeavour.

Bell's father , grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf, profoundly influencing Bell's life's work. Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications , hydrofoils , and aeronautics. Although Bell was not one of the 33 founders [10] of the National Geographic Society , he had a strong influence on the magazine while serving as the second president from January 7, , until Beyond his scientific work, Bell was an advocate of compulsory sterilization and served as chairman or president of several eugenics organizations.

A scientist is a person who conducts scientific research to advance knowledge in an area of interest. In classical antiquity , there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy , a precursor of natural science. In modern times, many scientists have advanced degrees [6] in an area of science and pursue careers in various sectors of the economy such as academia , industry , government , and nonprofit environments. The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras and before them, natural philosophers, mathematicians, natural historians, natural theologians, engineers, and others who contributed to the development of science have had widely different places in society, and the social norms , ethical values , and epistemic virtues associated with scientists—and expected of them—have changed over time as well. Accordingly, many different historical figures can be identified as early scientists, depending on which characteristics of modern science are taken to be essential.

How often do we take out the time to think about those extra ordinary minds who made life easier for us? Raman also worked on the acoustics of musical instruments. He was the first to investigate the harmonic nature of the sound of the Indian drums such as the tabla and the mridangam. He discovered that, when light traverses a transparent material, some of the deflected light changes in wavelength.

Thomas Edison unveiled the phonograph —which reproduced sounds by means of the vibration of a stylus following a groove on a rotating disc—in December Edison was projected into worldwide prominence and was dubbed the Wizard of Menlo Park. Thomas Edison played a significant part in introducing the modern age of electricity.
