What significance to inheritance systems have in evolution?
- Epigenetic results
- Jablonka and Lamb believe that induced and acquired changes have a role in evolution. Since each inheritance systems needs more study and observation by other researchers, these theories are somewhat controversial in the scientific community. DNA genetic system believes there are non random and semi directed mutations that occur in specific locations in the DNA. These mutations can be caused by the environment and have a greater degree of adaptability than genetic mutations.
- Epigenetic inheritance believes characteristics are developed by successful generational differences rather than passed through specific genes. Behavior is transmitted by example rather than genetics: food preferences, animals learning how to forage for food, birds learning to sing, mother ducks imprinting their ducklings, tribal traditions observed in chimpanzees and macaques communities. Cultural symbols, especially human language, have evolved and expanded through necessity for survival and various other factors not easily attributed to genetic transmission.
