New genetic research has identified the world's oldest known dog, dating back 15,800 years.

The discovery was made at the Pinarbasi rock shelter in Turkey, a site once used by ancient human hunter-gatherers. This dog is about 5,000 years older than the previously earliest genetically confirmed canine.

The findings suggest that dogs were already widespread and an integral part of human culture thousands of years before agriculture began. These results were published in two scientific papers in the journal Nature.

Hemoglobin

                                                                       F.L. Hünefeld 

F.L. Hünefeld discovered hemoglobin in 1840 when he observed bright-red crystalline structures in earthworm blood under a microscope.

Felix Hoppe-Seyler's 

Investigated the chemistry of the red blood pigment. He coined the term hemoglobin and demonstrated how it binds oxygen to form oxyhemoglobin.

Hans Fischer

German chemist Hans Fischer won the 1930 Nobel Prize in Chemistry for mapping the structure of heme (the iron-containing pigment in blood) and showing that it features an iron atom at the center of a large porphyrin ring system 

Max Perutz

Max Perutz used X-ray crystallography to determine the molecular structure of hemoglobin, the blood protein that carries oxygen. It took him over 20 years of research to solve the complex structure, earning him the 1962 Nobel Prize in Chemistry.
