Organism evolved subject to natural selection

“For close to 4 billion years, every single organism on the planet evolved subject to natural selection. Not even one was designed by an intelligent creator. The giraffe, for example, got its long neck thanks to competition between archaic giraffes rather than to the whims of a super-intelligent being. Proto-giraffes who had longer necks had access to more food and consequently produced more offspring than did those with shorter necks. Nobody, certainly not the giraffes, said, ‘A long neck would enable giraffes to munch leaves off the treetops. Let’s extend it.’ The beauty of Darwin’s theory is that it does not need to assume an intelligent designer to explain how giraffes ended up with long necks.”
