192 PART 2 / <strong>Evolution</strong>ary Genetics<br />

Further reading<br />

The texts by Graur & Li (2000), Page & Holmes (1998), and Li (1997) introduce the<br />

topic. The classic works, in order of decreasing age, are: Lewontin (1974), Kimura<br />

(1983), and Gillespie (1991). Kimura (1991) up-dated his views.<br />

The Festschrift for Lewontin (Singh & Krimbas 2000) contains a number of chapters<br />

on the topic. See Hardison (1999) on hemoglobin. Golding & Dean (1998) review<br />

studies of adaptation at the molecular level. Eanes (1999) reviews studies of enzyme<br />

polymorphism. The texts include material on levels of variation and rates of evolution.<br />

Przeworski et al. (2000) describe variation in human DNA. Mitton (1998) reviews<br />

classic, pregenomic studies of selection.<br />

On molecular clocks, see Cutler (2000) on irregularity or overdispersion. The mutation<br />

process matters for the generation time effects in the molecular clock. For number<br />

of germ line divisions see Ridley (2001, p. 234). Mutations are mainly internal copying<br />

accidents: see Ridley (2001), and Sommer (1995), for example. However, Kumar &<br />

Subramanian (2002) provide evidence that some synonymous evolution rates, and<br />

therefore perhaps mutation rates, in mammals do not depend on generation time.<br />

For nearly neutral theory, see the general texts. Ohta (1992) is a review, Ohta &<br />

Gillespie (1996) a historic perspective, and Ohta (2002) a recent update. The exchange<br />

between Ohta and Kreitman included in Ridley (1997) shows how various facts can be<br />

explained by the nearly neutral theory or selective evolution. Gillespie (2001) questions<br />

whether population size affects the rate of evolution, because the effect via hitch-hiking<br />

(Chapter 8) is the opposite of the effect on drift at one site.<br />

On testing for selection in genomic data, Nielsen (2001) reviews the statistical tests.<br />

Brookfield (2001) introduces one case study. Hughes (1999) looks at ratios of nonsynonymous<br />

to synonymous evolutionary rates.<br />

Another test, similar to the test of McDonald and Kreitman (1991), was devised by<br />

Hudson, Kreitman, & Aguade (1987). The “HKA” test is also enjoying a revival with<br />

genomic data. It can be seen in action recently in Rand (2000) on mitochondrial<br />

genomics, and Wang et al. (1999) on genetic change during maize domestication.<br />

Bustamente et al. (2002) is another paper using the MK test with genomic data, like the<br />

two discussed in the text. They agree that fruitflies have substituted many advantageous<br />

non-synonymous changes, and add an inference that Arabidopsis has substituted more<br />

disadvantageous changes. The Ohta–Kreitman exchange cited above considers the MD<br />

and HKA tests further.<br />

On codon biases, see Kreitman & Antezana (2000), Mooers & Holmes (2000), and<br />

Duret & Mouchiroud (1999).<br />

Research on this topic can be followed in Trends in Ecology and <strong>Evolution</strong>, Trends in<br />

Genetics, Bioessays, and the December special issue each year of Current Opinion in<br />

Genetics and Development.<br />
