Me ! darwin hypothesized that there are definite steps to natural selection. consider the model of bacterial resistance to antibiotics. how would darwin explain step i? question 1 options: bacteria adapt to environmental changes. some bacteria alter their dna in response to environmental changes. in any population, some individuals are weaker than others. in any population, genetic variation exists.

Two main types of bacteria on the basis of colur have shown in figure. Red type bacteria are more resisrtant than orange type bacteria. According to Darwin theory of natural selection, resistant bacteria are more favoured by nature because they can survive and not affected by drugs. As a result they will survive while orange will finish with the passage of time. Now reb bacteria as they survive will produce offspring and increase their population because the are survival of the fittest.

Yes i do hahahahahhaha
