"However from the moment of conception organisms have some limited ability to reorganize their development if circumstances warrent , and that ability to change decreases with age ."
"But if there are too many dogs wandering around they do not change to be cats , or rabbits , or humans do they . They do not change so as to have eight legs and spider eyes do they . But yes development of the phenotype is a result of the genetic heritage interacting with the environment , but its not an intelligent process . If you starve a young organism to near the point of death and then rescue it with food it will not develop as if it had food when it needed it . It will not express its full genetic potential . The environment OFTEN changes the outcome of development by imposing limits on reaching the biotic potential provided in the genome ."
