It's a double mutation that occurs on a colony of cells (bacteria for example) that claims to have resistance to two different antibiotics or viruses. This double mutation, however, strictly happens by first developing a mutation for the first antibiotic/virus and then has an independent mutation (nothing to do with the first mutation) for the other or second antibiotic/virus.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.

Zircnium was discovered first by Klaproth in 1789.
The mutation from GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU is a point mutation, specifically a substitution mutation. In this case, the first codon changes from GAA (which codes for glutamic acid) to GAU (which codes for aspartic acid). This type of mutation can lead to changes in the protein sequence, potentially affecting its function.

A clearly identified problem statement.
It first identified by Robert Koch
Bones first develop as cartilage models which gradually ossify into bone through a process called endochondral ossification. This process involves the replacement of cartilage with bone tissue, resulting in the formation of the mature bone structure.
The FIRST step!
what is the first living cell to get all its genes identified?
It was a team of scientist that first reported CFTR gene mutation in children with Cystic Fibrosis. The team worked in North-East of Iran.
There is no such thing as "the first duck." all things on earth evolved slowly, mutation by mutation, so that they fit their environment. Things that have good mutations live and have kids, and their kids have that mutation. That's how evolution works.

Oxygen was first identified as an element in 1774 by English chemist, Joseph Priestley
