In 1874, he published the book English Men of Science: Their Nature and Nurture, arguing that inherited factors were responsible for intelligence and other characteristics.

Nature and nurture are traditionally set in opposition to each other. ", "Decreased retinal ganglion cell number and misdirected axon growth associated with fissure defects in, "Emergence of orientation selective simple cells simulated in deterministic and stochastic neural networks", "Common SNPs explain a large proportion of the heritability for human height", "Why nature & nurture won't go away. A culmination of more than half a century of research collected on 14.5 million pairs of twins has finally concluded that the nature versus nurture debate is a draw. What the Research Says.

Men outperform women in sports requiring muscular strength and/or endurance, but the relative influence of "nurture" versus "nature" remains difficult to quantify. Part 1: Nature Versus Nurture.

To some parents, their donor sperm/egg might seem like just a donated cell or a piece of genetic material.

Even using experiments like those described above, it can be very difficult to determine convincingly the relative contribution of genes and environment. A person is born with specific skills and characteristics. People with extreme views are called nativists and empiricists. 1.
