Somatic Growth Rates-Implications for EvolutionEdit

Somatic growth rates can have important fitness consequences, be heritable, and evolve (Caley & Schwarzkopf, 2004). Biologists study somatic growth rates closely because of the relationship between growth and other fitness-determing traits. Additionally, it results from both genetic and environmentally induced variation (Gale, 2013).
