Evolution Quote by Adam Alter
““DNA evidence suggests that Neanderthals carried a gene known as DRD4-7R as long as forty thousand years ago. DRD4-7R is responsible for a constellation of behaviors that set Neanderthals apart from earlier hominids, including risk-taking, novelty-seeking, and sensation-seeking.””
About This Quote
The quote links a specific dopamine receptor gene to traits like risk‑taking and novelty‑seeking, suggesting Neanderthals possessed a genetic basis for adventurous behavior.
In simple terms: Neanderthals had a gene linked to bold, exploratory behavior.

When to use this quote
- archaeological interpretation of ancient DNA
- comparative studies of modern and extinct hominins
- explaining cultural differences in risk behavior
- designing behavioral interventions
Key Concepts
DRD4-7R gene
neurotransmitter receptors
evolutionary psychology
behavioral genetics
Practical Applications
- informing evolutionary models of cognition
- guiding research on genetic influences on personality
Questions to Reflect On
- How might modern humans' DRD4 variants affect their risk preferences?
- What does this imply about the role of genetics vs. environment in shaping behavior?
A Different Perspective
Other factors such as environment and culture also heavily influence risk‑related behaviors, so gene presence alone may not fully explain Neanderthal conduct.
