The last wild horses on Earth – Przewalski

Yesterday we got our story about the Przewalski horses published in Cell Current Biology. The article describes the world’s last remaining truly wild horses, which only comprises around 2,100 individuals worldwide. Eleven Przewalski horses were sequenced and compared to the genomes of 28 domesticated horses to provide a more detailed look at the endangered species which is shown to have diverged from Domesticated horses ~45.000 years ago. Finally the genomic impact of ∼110 years of captivity is also monitored, revealing reduced heterozygosity, increased inbreeding, and variable introgression of domestic alleles, ranging from non-detectable to as much as 31.1%.

For a great Photo story check out the Discovery news website.
