Can Environment Influence Genes?
Long Description: Two-part photo, with close-up views of a forager bee (left) and an undertaker bee (right).
Robinson discovers that environment changes honeybee job tasks and how fast bees grow up.
When forager bees are taken from the hive, younger "nurse bees" suddenly become active foragers.
Given a shortage of nurse bees, some bees never grow up, becoming "Peter Pans" that care for young bees.
Conclusion: Social regulation and environment affect brain genes and growth.
