Most ducks had more wobbing on their foet than their parents. The descendants would look the same as the original individuals because species do not change. O No, species do not change even after many generations, so individuals of the same species would not look different. They were made famous by Charles Darwin, who developed his theory of evolution in part by studying the birds.

Exposure to DDT caused specific, nonrandom mutations for DDT resistance within the population. There must be a sudden environmental change. (EQ: 9, 13) Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring. Popcornflix is a free over-the-top streaming service out there within the US and Canada. 2 years ago, Posted Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination).
