	Evolutionary biology portal This article is part of WikiProject Evolutionary biology, an attempt at building a useful set of articles on evolutionary biology and its associated subfields such as population genetics, quantitative genetics, molecular evolution, phylogenetics, and evolutionary developmental biology. It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy.

Millidarwins

RE this sentence: "Inexplicably, Haldane defined the millidarwin as 10−9 darwins, despite the fact that the prefix milli- usually denotes a factor of one thousandth (10−3)".

I can't access the cited source, but this seems to be based on a misunderstanding. Haldane is quite unclear in the paper, but the millidarwin is defined in terms of a yearly rate of 10^-9, which is one thousand times smaller than the darwin (at a yearly rate of 10^-6, or change over 1 million years). 137.82.81.147 (talk) 22:10, 26 February 2024 (UTC)[reply]

Conceptual Nonesense

How exactly are the initial and final "values" of a trait measured or quantified?

If this has yet to be determined and is only a mathematical model, then the equation itself is, arguably, arbitrary. — Preceding unsigned comment added by 75.172.123.126 (talk) 21:25, 4 December 2013 (UTC)[reply]

In the Beak of the Finch, the author says that one Darwin represents a change in attribute size of 1% over a million years. Maybe somebody could look to confirm that, and incorporate into article? 24.185.0.8 (talk) 22:10, 4 March 2017 (UTC)[reply]
