What evolutionary processes would lead a population away from an adaptive peak, towards lower average fitness, before ascending a different adaptive peak? 100 words or more please

Solution

\"Selection\" is the evolutionary processes would lead a population away from an adaptive peak, towards lower average fitness, before ascending a different adaptive peak becuase variation ibn two genetic loci have meticulous influence on a character & the intermediate phenotype has the more fiteness in aparticular environment. Therefore, it can concluded that \"selection\" is metioculous evolutionary fector is going to occur in apopulation as per \"rule of increased fitness\", wherea population from low-fitness valley to high -fitness \"adaptive peak\" & these aspects are mainly relies upon initial genetic composition of the population
