List 2 adaptations that helped Darwin's finches survive.?
Vaselesa [24]

Answer:

Two adaptations of Darwin's Finches that helped them to survive are:

  • Beak structure.
  • Behavioral adaptations to use tools for foraging.

Explanation:

There are fourteen species of Darwin's finches that originated from a single  species of ground dwelling seed eating finch.

These Finches occupied different niche in the Galapagos island  and were widely studied by Darwin.

These finches are one of the best Examples of Adaptive radiation.

Studies state that during severe drought in Galapagos island most vegetation dried out and a few softer seeds were left.

These few seeds were quickly fed upon by the birds and only dry , hard seeds were left.

Only birds who had large and hard beaks could feed on these hard dry seeds.

To Ensure survival the Finches developed adaptations which resulted in hard and large beaks so that they can feed on those dried hard seed.

Some groups started feeding on insects and got their beaks adapted to capture and kill insects.

Second line of adaptation included changes in behaviour and cognitive intelligence where birds started using tools for foraging.
