Mouse and man share 99% genetic similarity - including the genes to make a tail.
Humans and mice shared a common ancestor about 100 million years ago.
A mouse has about the same number of genes as a man.
Due to preserved genetic similarities, even after 530 million years of separation, introduced human genes can operate within the Fruit Fly genome.
The nematode worm shares many genes with human beings, including the genes to make muscle.
Puffer fish and Zebra fish are so genetically similar to human beings that their genomes are being deciphered as model organisms for research.
The California purple sea urchin (Strongylocentrotus purpuratus) genome has 23,300 genes, of which 7077 are shared with human beings.
The dog genome also reveals many shared genes and diseases with humans; about 94% of the dog genome shows conserved synteny with mice, rats and humans.
Birds and human beings have three very similar genes affecting blunt limb buds.
Genetic similarity between humans and chimpanzees is between 96% and 99.4%
LUCA, the Last Universal Common Ancestor existed around four billion years ago. We are probably descended from a mud-burrowing worm.
The common ancestor of all placental mammals was probably a small nocturnal shrew-like creature, snuffling about more than 80 million years ago.
Dogs, goldfish, and ferns have more chromosomes than human beings.
75% of our genetic make-up is the same as a pumpkin - 57% the same as a cabbage.
The split between plants and animals occurred about 1.6 billion years ago.
Around 100 genes in flowering plant Arabidopsis thaliana (Thale Cress) are closely related to human disease genes; and Arabidopsis has most of its genes in common with all other plants on Earth.
