A study has found that urban air pollution - ozone and nitrogen dioxide - causes changes in general expression in sperm, with potential impacts on foetal development.

More evidence of the environment producing subtle heritable modifications to DNA.

The world we live in is still far more Mendel's than Lamarck's, but it's perhaps more like 95:5 rather than 100:0.

Not to speak well of air pollution, but the article seems far too eager to implicate it in reducing male fertility.

Alternate theory: The pollution-induced epigenetic changes are mostly to adapt any offspring to living in an environment with more-polluted air. Given how often our ancestors used indoor air pollution (from cooking fires and such) to discourage disease-spreading insects, that would be a very reasonable adaption.
