The speed of how medium ground finches have been able to change beaks' sizes and shape may be centered around epigenetics. A research team led by Ms. McNew on the Galápagos Islands has measured the physical traits of wild birds and the genetics and epigenetics of two Darwin's finch species living at El Garrapatero, a rural area.
Islands such as Isabela Island contained cold and nutrient-rich waters that provided abundant food, ensuring the survival and reproduction of penguins. [10] Over millions of years, the penguins underwent adaptations, developing unique features that enabled their existence and allowed them to thrive under such an ecological niche. [ 10 ]
It is the southernmost island in the Galapagos Archipelago, and a 3,400 m submarine escarpment 10 km south of the island forms the southern boundary of the Galapagos Platform. There are over 50 scoria cones onshore and 6 tuff cones offshore.
Isabela Island (Spanish: Isla Isabela) is the largest of the Galápagos Islands, with an area of 4,586 km 2 (1,771 sq mi) and a length of 100 km (62 mi). By itself, it is larger than all the other islands in the chain combined, and it has a little under 2,000 permanent inhabitants. The island straddles the equator.
The Galápagos Islands are home to a remarkable number of endemic species. The stark rocky islands (many with few plants) made it necessary for many species to adapt to survive and by doing so evolved into new species. It was after visiting the Galápagos and studying the wildlife that a young Charles Darwin developed his theory of evolution. [2]
