Researchers on the Indian Institute of Science Education and Research (IISER) Bhopal have constructed a high-quality genome meeting to decode the genetic secrets and techniques of the peacock, India’s nationwide chicken.
The ornate options of the peacock’s tail have at all times fascinated scientists and nature lovers. Even Charles Darwin, often called the daddy of evolution, had expressed bewilderment over the paradoxical grand show of the male peafowl, which made it extra susceptible to predators.
Darwin resolved this puzzle with the speculation of sexual choice, suggesting that such decorative traits play a vital position in attracting mates and enhancing reproductive success.
Despite this understanding, the underlying genetic foundation for these spectacular birds has at all times remained a thriller.
In the brand new examine, printed within the journal Heliyon, the crew targeted on the Blue Peafowl, also referred to as the Indian Peacock, native to the Indian subcontinent, and the Green Peafowl, present in Southeast Asia.
These two species of birds had been chosen as a result of regardless of being the one two species from the Pavo genus, the Blue Peafowl is classed as a species of “Least Concern,” whereas the Green Peafowl faces endangerment attributable to a decline in inhabitants measurement.
They sought to know the evolutionary and genetic causes for his or her differential adaptability that makes the Blue Peafowl much less endangered than the Green.
Researchers discovered that genes associated to nervous system growth, immunity, and skeletal muscle growth have undergone adaptive evolution in each chicken species.
However, the Blue Peafowl has extra pronounced adaptive evolution, possessing a better variety of expanded gene households, segmentally duplicated genes, species-specific gene clusters, and genes with evolutionary signatures.
“Our findings highlight the distinct genomic divergence between the two Asian peafowl species and provide valuable genomic clues to explain their contrasting population sizes,” stated Vineet Ok. Sharma, Associate Professor, Department of Biological Sciences, IISER Bhopal, in a press release.
“The green peafowl population appears to be more vulnerable to the consequences of habitat loss and human exploitation for food and commercial use. These activities have had a greater impact on their numbers, as they are less tolerant to human disturbances.
“The reduction in their population has resulted in decreased gene flow, increased inbreeding, and lower genetic diversity, ultimately raising the risk of extinction for this species,” Sharma added.
