[Soliton]

One more question, repeated - did that article from Australia mention in any way how they know the shrub was around 40,000 years ago?


This shrub grows like a creosote bush (look it up). It has rings that show how old each section is.

Number of rings X number of sections = years.

Creosote bushes in America have been found to be up to 10,000 years old.

[agrace]

Number of rings X number of sections = years.

How do they know? Have they observed how fast the rings grow? And is growth always constant?
