Hi Sally,

Over here it is winter, so I am here at my desk a great deal!

Dating genetic changes is likely 'largely' accurate, but it is important to attempt direct dating of sample fossils. There are some problems with molecular clocks which are highlighted, here, here and here.

Carbon dating is no use for most hominin fossils, it is only accurate for samples younger than 50,000 years. To directly date the older fossil finds requires geological dating methods, such as thermoluminescence dating, molecular spin resonance dating, dating by associated micro fossils and relative dating (comparative to other well dated aspects of the archaeological sites). It is usually best to employ several dating methods and calculate a realistic mid point and a margin of error - a margin of error can be even ten thousand years either side of the suggested date, so we are lucky when a precise date emerges.

Please do question away, I am happy to attempt to provide answers.
