A study has revealed that wild chimpanzees have evolved distinct genetic adaptations to their environments, particularly to combat diseases like malaria.Researchers analyzed genetic material from 388 chimpanzees across 18 African countries, uncovering how local conditions have shaped the species' genetic diversity.Chimpanzees living in dense tropical forests, where malaria is more prevalent, were found to have genetic changes associated with resistance to the disease. These adaptations were observed in genes also linked to malaria resistance in humans, suggesting parallel evolutionary responses to the same pathogen. In contrast, woodland-savannah chimpanzees showed no evidence of similar adaptations, likely due to the reduced malaria pressure in their habitats.Chimpanzees, along with bonobos, are the closest genetic relatives to humans, sharing approximately 98.8% of human DNA. Their evolutionary history and adaptations provide valuable insights into human biology, particularly in understanding how genetic mechanisms respond to environmental pressures like infectious diseases.The findings have significant implications for conservation. The study emphasized the need to preserve the genetic diversity of chimpanzees, including the variations that enable them to adapt to changing environments. Researchers warned that habitat destruction and climate change may have varying impacts on different chimpanzee populations. For instance, forest degradation poses a greater threat to forest-dwelling chimpanzees, while changes increasing malaria risk could disproportionately affect woodland-savannah populations.With wild chimpanzee numbers estimated at just 170,000 to 300,000, conservation efforts must address both habitat preservation and the maintenance of genetic diversity to ensure the species' long-term survival in the face of environmental changes.

Wild Chimpanzees Show Unique Genetic Adaptations to Diverse Habitats and Diseases

The research, conducted by scientists from University College London and published in the journal Science, is based on genetic material extracted from fecal samples collected across equatorial Africa. These samples were gathered from 52 sites spanning countries such as Cameroon, the Democratic Republic of Congo, Uganda, and Ghana.
A study has
revealed that wild chimpanzees have evolved distinct genetic adaptations to their environments, particularly to combat diseases like malaria.
Researchers analyzed genetic material from 388 chimpanzees across 18 African countries, uncovering how local conditions have shaped the species' genetic diversity.
Chimpanzees living in dense tropical forests, where malaria is more prevalent, were found to have genetic changes associated with resistance to the disease. These adaptations were observed in genes also linked to malaria resistance in humans, suggesting parallel evolutionary responses to the same pathogen. In contrast, woodland-savannah
chimpanzees showed no evidence of similar adaptations, likely due to the reduced malaria pressure in their habitats.
Chimpanzees, along with bonobos, are the closest genetic relatives to humans, sharing approximately 98.8% of human
DNA. Their evolutionary history and adaptations provide valuable insights into human biology, particularly in understanding how genetic mechanisms respond to environmental pressures like infectious diseases.
The findings have significant implications for conservation. The study emphasized the need to preserve the genetic diversity of chimpanzees, including the variations that enable them to adapt to changing environments. Researchers warned that habitat destruction and
climate change may have varying impacts on different chimpanzee populations. For instance, forest degradation poses a greater threat to forest-dwelling chimpanzees, while changes increasing malaria risk could disproportionately affect woodland-savannah populations.
With wild chimpanzee numbers estimated at just 170,000 to 300,000, conservation efforts must address both habitat preservation and the maintenance of genetic diversity to ensure the species' long-term survival in the face of environmental changes.
