The evidence for hereditary influences onintelligence comes mainly from studies ontwins and adopted children. Theintelligence of identical twins rearedtogether correlate almost 0.90. Twinsseparated early in childhood alsoshow considerable similarity in theirintellectual, personality and behaviouralcharacteristics. The intelligence of identicaltwins reared in different environmentscorrelate 0.72, those of fraternal twinsreared together correlate almost 0.60, andthose of brothers and sisters rearedtogether correlate about 0.50, whilesiblings reared apart correlate about 0.25.Another line of evidence comes from thestudies of adopted children, whichshow that children’s intelligence is more

Similar intelligence test scores for identical twins reared apart are taken as evidence for the:
