Can giraffes turn their necks?
Giraffes use their necks in the same way we use ours. They are just longer.
How do giraffes adapt to get food?
Longer necks.
What would need to happen so that giraffes with really long necks evolved?
I'm guessing that food was scarce near the bottom of trees, so giraffes with longer and longer necks generally outlived the giraffes with shorter ones.
Darwin and Lamarck had different ideas about why all giraffes now have long necks why?
Lamarck would have said that the ancestors of modern-day giraffes had short necks but stretched their necks as they tried to reach leaves in trees; so, their descendants were born with longer necks. Darwin would have said that in a population of ancestral giraffes, some had slightly longer necks than others; the long-necked giraffes were better able to feed on tree leaves and as a result produced more offspring. Over time, the proportion of longnecked giraffes in the population increased.
If Lamark and Darwin had debated why giraffes have such long necks how would their explanations differed?

Explains how new species evolve from existing species?
Mutation. Giraffes got longer necks then, say, elephants, because some giraffes had slightly longer necks than others. These got more food, so survived, and had long necked children. Eventually they ended up like moodern giraffes
