Genome Evolution
Genomic evolution is the process that changes the structure (sequence) or size of a genome over time.
The study of genome evolution involves multiple fields such as structural analysis of the genome, the study of genomic parasites, gene and ancient genome duplications, polyploidy, and comparative genomics. Evolutionary biologists are interested in five specific questions in regards to evolution of the genome, these are:
- How did the genome evolve into its current size?
- What is the content within the genome, is it mostly junk or not?
- What is the distribution of genes within a genome?
- What is the composition of the nucleotides within the genome?
- How does translation of the genetic code evolve?

“As a natural process, of the same character as the development of a tree from its seed, or of a fowl from its egg, evolution excludes creation and all other kinds of supernatural intervention.”
