|
The finches were dying off rapidly, creating a wide variety in characteristics
|
|
|
The finches were competing against each other, creating shifts in the gene frequencies
|
|
|
The finches had adapted to the different food sources in their habitats, leading to a shift in the gene frequencies
|
|
|
The finches were impacted by different diseases in their different environment
|
Detailed explanation-1: -Different finch populations evolved to eat different food sources. Some finches on some islands evolved thin, sharp beaks that helped them to eat insects and the blood other larger animals; on other islands, finches evolved large, sturdy beaks ideally adapted to eating seeds, berries and nuts.
Detailed explanation-2: -They famously evolved to have different beaks which are suited to different food types such as large seeds and invertebrates, allowing them to occupy different niches. Darwin’s finches are all very similar in shape, size and colour, but there are a few differences which can help when identifying them.
Detailed explanation-3: -The diversity in the type of beaks of finches adapted to different feeding habits on the Galapagos islands is considered as an example of adaptive radiation and serves as an evidence for the origin of species by natural selection.
