A comprehensive review of 280 scientific studies reveals that natural selection can occur on multiple levels of biological organization, including individual and group benefits. This finding challenges the traditional view of natural selection and highlights its complexity in various ecosystems.
A recent study by the University at Buffalo has discovered that genetic variations affecting immunity and metabolism have been preserved in humans for millions of years. This finding supports the theory of balancing selection, which suggests that certain genetic traits can be beneficial or harmful depending on environmental conditions.
Researchers discovered that rattlesnakes' venom evolves through balancing selection, favoring genetic diversity and a diverse set of tools to subdue prey. This finding has implications for developing anti-venom therapeutics to better treat snakebites globally.
A new study found that spotted salamanders' egg mass coloration is influenced by two opposing evolutionary forces: genetic drift and balancing selection. In small populations, genetic drift drives changes in morph frequencies, while balancing selection helps preserve multiple traits.
The study found that balancing selection increases immune system gene diversity, which leads to a higher frequency of harmful gene variants. This suggests that our genetic adaptation to new pathogens comes at a cost, allowing some high-risk gene variants to persist in the population.
A recent study found that balancing selection can increase the frequency of harmful mutations in non-HLA genes within the MHC region. This mechanism may contribute to the prevalence of heritable diseases. The research team used DNA sequencing data from 6,500 individuals to test this hypothesis.
