And this is just one change in this group of penguins.
————
Meanwhile, near the equator, another group of penguins is speeding towards Antarctica.
Penguins have long been known to the world as chubby birds that cannot fly on Antarctic glaciers.
In fact, penguins' habitat is not relatively narrow. In addition to the extremely cold Antarctic, penguins can also live in temperate regions with distinct seasons, and even near the equator where the temperature is 20-30 degrees Celsius.
Penguins are an ancient type of waterfowl, and their ancestors may have lived in Antarctica before the formation of the Antarctic glaciers.
Around 65 million years ago, drastic changes in climate conditions occurred in a short period of time, leading to the extinction of half of the species, including dinosaurs. The surviving species entered the next evolutionary period. Penguins originated around this time. They are chordates and birds, but they cannot fly.
As for why it can't fly, there are two guesses.
The first one is that penguins never fly.
The second explanation is that penguins were originally able to fly, but faced difficulties in survival during the evolutionary process. They were forced to give up their ability to fly and live a life on land and in water. After natural selection and elimination, the wings of their offspring gradually evolved into flippers, forming their current appearance.
However, based on the fossil evidence unearthed, the first possibility is more likely.
The penguins heading towards Antarctica are the Gadgoon penguins, a species of penguin that lives near the equator.
The Gadjah penguin stands 44-53 cm tall and weighs 1.7-2.6 kg. Sexual dimorphism is observed, with males being slightly larger than females.
They live in the Galapagos Islands near the equator, spanning both the Northern and Southern Hemispheres, hence the name "equatorial penguins".
Equatorial penguins and Antarctic penguins have many different characteristics. For example, equatorial penguins are very small, standing only about 50 centimeters tall and weighing 2.5 kilograms. They have pink eyes, stripes on their chests, and spots on their bellies.
To stay cool, equatorial penguins forage in the sea during the day and roost on land at night, sometimes spreading their flippers or panting rapidly to dissipate heat.
