Evolution is a slow natural process occurring in living organisms which explains the formation of the diversity of organisms on Earth. In simple terms, evolution explains how life survived on Earth after the origin of life but it cannot explain the origin of life. However, modern evolutionary biologists are now trying to decode the origin of life through evolutionary evidence and support that earlier form of life originated in the large oceans around 3.5 billion years ago. These organisms are simple living unicellular organisms which later evolved into the eukaryotic organisms.
Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.
A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.
Under a microscope, chromatids look like little dots and chromosomes are lines.
