New research indicates that kids whose fathers spend more time with them have a higher IQ and are more socially mobile than those children who receive little attention.
The research shows that strong fatherly involvement in children's early life can improve their child's future career prospects.
The study was carried out by academics at the University of Newcastle.
The boffins also found that men tended to pay more attention to their sons than their daughters.
The researchers warned that it was not enough for parents to live together, but that a father should be actively involved in a child's life to benefit their development.
The study looked at more than 11,000 British men and women, born in 1958.
The scientists asked their mothers how often the father of their child took part in activities with them, including reading, organising outings and general "quality time".
The study has been published in the journal Evolution and Human Behaviour.
The analysis revealed that those children whose fathers spent more time with them had a higher IQ and were more socially mobile than those who had received little attention.
The differences were still detectable by the age of 42.
"What was surprising about this research was the real sizeable difference in the progress of children who benefited from paternal interest and how thirty years later, people whose dads were involved are more upwardly mobile," Telegraph quoted Dr Daniel Nettle, who led the research, as saying.
"The data suggest that having a second adult involved during childhood produces benefits in terms of skills and abilities that endure throughout adult life," he added.
