Episode notes
Planaria Barium Adaptation
- Planaria exposed to barium developed resistance, regenerated barium-adapted heads, and showed genetic changes despite lacking prior exposure.
- This demonstrates cells' problem-solving abilities beyond genetic inheritance.
Picasso Tadpoles
- Picasso tadpoles with scrambled facial features developed into normal frogs.
- This highlights cells' goal-directed actions and collective intelligence, rather than hardwired development.
Frog Limb Regeneration
- Levin induced limb regeneration in adult frogs by manipulating bioelectric signals, demonstrating the role of bioelectricity as a cellular language.
- This shows that cells can be directed towards goals beyond their genetic code.
