Teenage elephant mums die younger but are fitter
http://www.bbc.co.uk/nature/26436315
Elephants that give birth as teenagers die younger, but are fitter than mothers that delay, say scientists.
Researchers studied Asian elephants working in the timber industry in Myanmar, also known as Burma.
Mothers that gave birth younger were found to have larger families overall, and this greater genetic legacy is considered "high fitness".
Experts suggest a full understanding of the animals' reproductive health could reduce the strain on wild populations.
