Modern World Flashcards
What was scientific understanding?
By the start of the 1900, the work of Robert Koch had made the belief in germs universal and people began to search for even deeper causes of the disease such as causes connected to the “pathways of the body”.
What was advanced understanding of causes of disease?
As the 20the century progressed, better understanding of how diseases are connected to our body’s “pathways” developed. Understanding of hereditary diseases developed. Hereditary diseases are diseases that are built into our DNA and genes and can be inherited from our parents, grandparents and even ancestors.
What were key developments in understanding causes of disease in the modern world?
1953 - Structure of DNA understood.
1990 - Launch of the Human Genome Project.
2000 - WIth the completion of the mapping of the human genome it became possible for scientists to use the blueprint of a human’s DNA to look for mismatches or mistakes in the people suffering from hereditary diseases.
Greater emphasis on lifestyle factors
Throughout the 20th and 21st centuries, researchers have gone further into looking at how things like diet and exercise have direct causal links to illnesses such as a cancer and diabetes.
Is anything the same in the modern world compared to Medieval times when it comes to understanding the causes of disease?
Things like the importance of diet and exercise have been hunches or rational thoughts linked as far back as to Ancient times, however we now approach them with scientific confidence.
What was Archibald Garrod’s importance?
In 1902, Garrod theorised that hereditary diseases are caused by missing information in the body’s chemical pathways.
What was Rosalind Franklin, James Watson and Francis Crick’s importance?
In 1951, Franklin photographed DNA. In 1953, with the help of these images, Watson and Crick published a paper proving an understanding of its structure, meaning that the parts of DNA that were causing hereditary diseases could now be explored.
