Biology can’t run on genes alone
-
UC DAVIS (US) — Don’t lose the organism in the excitement over its genes, say biologists, who caution against straying too far from the actual plants, animals, and microorganisms.
The team suggests that decades of focus on genes have led the scientific community away from a balanced exploration of the organisms that those genes define.
In an article appearing this week in the journal BioScience, the researchers assert that genetic variation alone does not adequately explain the intricate variations in the physiology and behavior of complex organisms.
They propose a renewed emphasis on studying individual organisms in the context of specific environments, considering in greater depth the unique environmental exposures and experiences over the course of these organisms’ lives.
“Biology’s strong focus on genes during the past 50 years has generated a solid foundation for studying the mechanisms that determine the phenotype—the structure and function—of living organisms,” says Dietmar Kueltz, a professor of physiological genomics in the University of California, Davis department of animal science.
He notes that despite the wide-ranging practical implications, little is known about how such mechanisms are influenced by the unique lifelong sequence of environmental exposures experienced by individuals.
