However, on occasion one of the bacterial offspring will contain a mutation that is able to survive the specific antibiotic. This bacteria will then reproduce and the whole disease mutates. Eventually the new strain is infecting everyone and the old antibiotic has no effect on it. This process...
Later, these feathers evolved into more specialized forms that may have helped their bearers shelter their eggs and offspring (Hopp and Orsen 2004), attract mates with elaborate displays (Zhang et al. 2008), or improve traction as the flapping animal ran up an incline (Dial 2003). Somewhere...

That means a dilemma exists of being an all-black feline. Visual communication is essential, especially between conspecifics and offspring. Many species have white or light-colored fur on the backs of their ears to make it easy to be seen when it’s important, such as bringing food to their...
In mammals, female reproductive output is limited by the number of offspring that can be produced in a single reproductive cycle as well as by the length and energy requirements of gestation and lactation periods. Males, on the other hand, may, hypothetically, sire an almost unlimited number of...
which involves targeting sex cells, like eggs and sperm, or fertilized eggs. This makes CRISPR edits heritable between an animal and its offspring. Van Eenennaam's group doesn't insert newly engineered genes into cattle, but rather, they transfer existing, desirable genes from one cow into anot...
An allele that promotes better growth in hot weather may promote inferior growth in cold weather, for example. One thing to notice in Deppe's quote is that a mutation in a single gene may have no effect on an organism, or its offspring, or its offspring's offspring. For example, ...
The point is that evolution in general is an extremely slow process. When two mice breed, the offspring is a mouse. When that offspring breeds, its offspring is a mouse. When that offspring breeds... And the process continues. Point mutations do not change this fact in any significant way...
