A recent evolutionarily adaptation to dairy consumption, and has occurred independently in both northern Europe and east Africa.
Anatomically modern humans first appear in the fossil record in Africa about 195,000 years ago.
Homo sapiens first appeared in Africa around 300,000 years ago during the Middle Pleistocene.
The first key hominid trait to appear in the fossil record is bipedalism, which refers to the ability to walk upright on two feet. This adaptation is characteristic of early hominids and distinguishes them from their primate ancestors.
The first group of hominids is believed to have first appeared in Africa, around 6-7 million years ago. This is supported by fossil and genetic evidence.
Early man first appeared in the Cenozoic Era, specifically during the Quaternary Period. This era began around 2.6 million years ago and continues to the present day.

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.
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.
NO
It is believed to have been a mutation of a dinosaur.
Actually, not all cheese has lactose. Typically hard aged cheeses, such as cheddar, contain little to no lactose. All Cabot cheeses contain zero (0) grams of lactose. Eating any aged cheese should not affect those with lactose intolerance, regardless of how much is eaten, because lactose - the major carbohydrate of cheese - totally disappears within 3 to 4 weeks after the cheese is made. (first answer: yes yes yes)
