 " Evolution is not a process of ruthless competition directed to some goal of ever @-@ increasing power or complexity . Such an attitude , by failing to be adaptive , is , in fact , not conducive to evolutionary success . A species co @-@ evolves with its environment . Equally , there is no stable , harmonious nature to whose wisdom humanity should simply submit . Intelligent purpose plays a role in adaptive behaviour , and as environments change its role is increased . "
