, 01:35, September 24, 2011→Declining human fertility
While it is true that human fertility is declining, in this context "fertility" is a measure of birthrate, and the decline is due to social factors and increased life expectancy. There is an issue of a decline in male sperm count, but this appears to be linked to water pollution and is recent; there was no evidence of a decline before 1960. The most likely culprit is residual DDT breakdown products, which have also been linked to feminisation in freshwater fish. This is not evidence for a young Earth. --[[User:SamCoulter|SamCoulter]] 20:24, 23 September 2011 (EDT)

:The key point here is that to be valid the counterexample presumes that the rate of the process has been consistent throughout history. However, as with this case, for all counterexamples resting upon this assumption there is no reason to believe that this is true; indeed for some it is perfectly obvious that it is not so. As such, I propose that all counterexamples that are dependent on this assumption be removed. [[User:DavidZa|DavidZa]] 21:32, 23 September 2011 (EDT)

::Although probably for very different reasons, I agree. Uniformitarianism is a deeply flawed assumption normally associated with evolutionism and "old Earth" geology, and CP shouldn't (and doesn't need to) use it. If you're interested I have a couple of articles (peer-reviewed, not from AiG or any Hovindite loons) questioning this assumption; email me if you want them. My address is on my user page. --[[User:SamCoulter|SamCoulter]] 21:35, 23 September 2011 (EDT)
