Oct 30, 2017 · Understanding when and how genes first came together to form genomes is a fundamental puzzle in the study of the origin of life. Genes are naturally selfish, and yet, life started with cooperation between genes.

Experts think that the first step towards life was simply a molecule that was capable of self-replicating. As a geneticist, your mind might jump straight away to the most famous self-replicating molecule of them all, DNA. Click here to explore the ideas behind the origins of RNA and DNA.
As far as we can tell, all of life on earth evolved from one common ancestor, LUCA, which must have had one set of genes, whatever they looked like. But that leaves the question of how this simple set of genes diversified to encompass the incredible diversity of genes that now exist in trillions of extant and extinct species on earth.

The emerging field of xenobiology is a subfield of synthetic biology that involves using chemical substances not usually found in nature, for example, alternative DNA known as XNA, short for Xeno Nucleic Acid. Click here to learn about how some experts in the field are adding new letters to the genetic alphabet by creating XNA with completely new n...
Modern genetics began with the work of the Augustinian friar Gregor Johann Mendel. His works on pea plants, published in 1866, provided the initial evidence that, on its rediscovery in 1900's, helped to establish the theory of Mendelian inheritance.
1866 - Gregor Mendel discovers the basic principles of genetics. In 1866, an unknown Augustinian monk was the first person to shed light on the way in which characteristics are passed down the generations. Today, he is widely considered to be the father of genetics.
Nov 9, 1991 · How did life begin? Revolutionary discoveries about the genetic material RNA are helping molecular biologists to piece together replicas of the first genes
The history of genetics can be represented on a timeline of events from the earliest work in the 1850s, to the DNA era starting in the 1940s, and the genomics era beginning in the 1970s.
Aug 12, 2009 · But where did the first genomes come from—and how? What rules govern how they function and what they look like? And why do they vary so much in size from organism to organism?
