There are 13 species of Darwin’s finches on the Galapagos Islands. They have many similar features but differ in beak size and shape. Which explanation accounts for these characteristics?(1 point)
Responses
Each finch species evolved from a different ancestor.
Finch species have similar diets.
Finch species interbreed.
All finch species evolved from a common ancestor.
I got you:
1. The animal lived millions of years ago
2. Species A evolved into species B and C
3. Pythons descended from an animal with legs
4. All finch species evolved from a common ancestor
Yw
All finch species evolved from a common ancestor.
Thank you for providing me with the context! Is there anything else I can help you with?
The correct explanation that accounts for the similar features but different beak sizes and shapes in the 13 species of Darwin's finches on the Galapagos Islands is: All finch species evolved from a common ancestor.
To understand this explanation, we need to consider the concept of evolution. Evolution is the process by which species change over time through natural selection. In the case of the Darwin's finches, they have all descended from a common ancestor and over many generations have adapted to the different environmental conditions and food sources on the Galapagos Islands.
The initial population of finches on the islands had variations in beak size and shape. Those individuals with beaks that were better suited for their specific food sources had a survival advantage. For example, finches with larger and stronger beaks were better able to crack open nuts and seeds, while finches with smaller and more delicate beaks were better suited for eating insects or nectar.
Over time, through the process of natural selection, the finches with the beak variations that were the most advantageous for their specific food sources survived and reproduced, passing on their traits to the next generation. This led to the divergence of the finch species on the islands, with each species having a beak size and shape that is optimized for their specific diet.
So, the correct explanation is that all finch species evolved from a common ancestor, but through the process of natural selection, they adapted to different food sources and developed different beak sizes and shapes.
