Francis Galton based his theory of inheritable traits on the analysis of biographical data of prominent individuals and their families. This led to his development of the concept of "nature vs. nurture" and eventual contributions to the field of eugenics.

The individual differences theory was propounded by Francis Galton, a British psychologist and statistician. He believed that differences observed among individuals in various traits and abilities were due to both hereditary and environmental factors.
The theory states that there is inheritable variation among offspring, and that as environments change some variations will enjoy an advantage over others. In other words, there will be preferential survival of beneficial inheritable traits, which will ultimately be reflected in the general population. This constitutes evolution.

the DNA of an organism, determining its specific traits. It consists of the genetic makeup of an individual, including all the genes present in their genome.
Fossils depict gradual changes in species over geologic time. This was one primary bit of evidence for Darwin's theory. Another was the similarity in species separated by geography. Race circles are one example of this. Variations introduced by pigeon breeders demonstrated that variations resulted in inheritable traits. Today we also have DNA, which clearly demonstrates common ancestry between species.
Evolution by natural selection, proposed by Charles Darwin, suggests that individuals with advantageous traits are more likely to survive and pass on those traits to their offspring, leading to changes in populations over time. Lamarck's view of evolution, on the other hand, proposed the inheritance of acquired traits, where organisms could pass on traits that they acquired during their lifetime. The key difference is that in natural selection, the advantageous traits are already present in the population and selected for, while Lamarck's theory suggests that organisms can actively acquire and pass on new traits.
Mendel's theory of the transfer of traits, also known as Mendelian inheritance, states that genetic traits are determined by the inheritance of alleles from parents. These alleles segregate independently during gamete formation and randomly combine during fertilization, resulting in offspring with specific traits based on the combinations of alleles inherited.
