acquired traits of an individual organism during its lifetime cannot direct the evolution explain the statement with an illustration
Answers
Acquired traits are due to changes in the lifestyle, injury, loss of body parts, disuse of some body parts. These are the traits which occur in the somatic cells. These changes occur in the non-reproductive tissues, these cannot be passed into the DNA of the germ cells. hence acquired characters are not inherited.
ANSWER
starvation will not change the DNA of the germ cells . Therefore , low weight is not a trait that can be inherited by the progeny of a starving beetle . therefore , even if some generations of beetles are low in weight because of starvatio , that is not an example of evolution , since the change is not inherited over generation . change in non-reproductive tissue cannot be passed on to the DNA of the germ cells . therefore the experience of an individual during its lifetime cannot be passed on to its progeny . and cannot direct evolution.
