Outrageously Funny Word Dictionary :: Lamarckianism

👉 Lamarckianism refers to a biological theory that suggests that traits, such as height and intelligence, are determined by genetic inheritance rather than environmental factors. Lamarckists believe that individuals acquire their traits through natural selection, which is driven by their fitness in their environment. This means that the more advantageous traits (height, intelligence) are passed on to offspring, while the less advantageous ones (poor health, low IQ) are not passed on at all.
