Given what you know about g. fortis, g. magnirostris, and the big bird lineage, what do you predict will happen as the drought continues?

As drought continues, there is a tighter competition for survival since food becomes scarce. Creatures will adjust based on how they acquire food. Seed is the determining factor for the evolution of the birds’ beaks. Larger G. fortis compete with G. magnirostris for large seeds. But due to continuing droughts, food will become increasingly scarce resulting in the death of many G. magnirostris and G. fortis with large beaks, including the big bird lineage. And also, beaks of G. fortis will further reduce in size to be able to consume any available food sources.

i think it is dna, i'm not totally sure but i think it might be.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
