1. You come across a small 4-legged organism (approximately 40 cm high, weight approximately 6 kg) with a feather-like outer covering. It inhabits the scrubby grass strips between the sea and the desert. As you observe the animal, you notice that after grazing on the grass, it walks to the sea and drinks the water. What adaptations might this organism have to be able to drink seawater? Explain
2. You find a fossilized skeleton of a medium sized organism. The organism has long slender limbs, appears to have an arm length of about a foot, and has slender fused bones in the arms and legs. If this were the fossil of a flying organism, what other characteristics would you look for on the fossil and why would you look for them related to the ability to the organism to fly?
