(2004) Plomin & Spinath discuss intelligence in the wider context of genetics, genes, and genomics.
Their discussion is multi-faceted; their analysis illustrates proof of the genetic heritability of intelligence, the immense weakness of environmental explanations for intelligence, changes in heritability during development, a multivariate analysis of IQ and various testing metrics, gene expression profiling, and genomics.
This is an excellent compilatory piece.

(2009) Rushton & Jensen refute erroneous claims made about the nature of the Flynn Effect and its relationship with the Black-White IQ gap.
In their conclusions they state, "We conclude that predictions about the Black–White IQ gap narrowing as a result of the secular rise are unsupported. The (mostly heritable) cause of the one is not the (mostly environmental) cause of the other. The Flynn Effect (the secular rise in IQ) is not a Jensen Effect (because it does not occur on g)."

(2001) Rushton & Rushton show evidence for racial-group differences in the form of brain size and structure, IQ, and musculoskeletal trait variation.
Their analysis shows significant variation in both the structure and sizes of the brains of Negroids, Caucasoids, and East-Asians. In addition to this, they have found differences in the skull shapes and structures of the races, alongside differences in average height and weight and all parts of the bone and muscle structures from the neck to the feet.
