Penguins are the only birds in the world that cannot fly and can only dive. The penguin family is widely distributed in the southern hemisphere, and there are 18 species in existence. How many of the 18 species of penguins in the world do you know? When did penguins start living such a unique lifestyle and become the weirdos among birds? And do penguins set out from Antarctica to explore Africa and Australia, or do they go from Africa and Australia to the ice-covered Antarctica? Scientists have been noisily arguing regarding these issues since 2005, and there is no conclusion yet. The oldest penguin fossil excavated so far is the Waimanu unearthed in New Zealand in 1980. It is estimated to be regarding 60 million years ago, in the Paleogene period of geological time. . Wai Ma Lu was regarding 65-100 centimeters tall and weighed 10-30 kilograms, regarding the same as today’s king penguins. The crooked penguin has a long beak, its wings are shorter than other birds, and its bones are flatter, forming a blade shape suitable for water skiing (this shows that its flight ability is probably no longer good). The short legs and upright appearance of the crooked road penguin are almost the same as those of modern penguins, and they can walk very well on land. The oldest penguin ancestor found so far is the Waimanu penguin from the Paleocene 60 million years ago. Its long beak and neck are different from modern penguins. But they already have short, flat wings suitable for diving, short and wide feet, and an upright body shape suitable for walking on land. Do you think penguins have never thought regarding leaving the circle of dwarf melons? That’s wrong. After 20 million years, a giant penguin appeared in the Eocene (Ecocene). It might be nearly 200 centimeters tall and weigh up to 100 kilograms. It was simply a winning streak in the penguin world (win article). How many times are you going to be shot on this board… Please listen to the BMI gap between Jeremy Lin and Lian Shengwen: Juliana Vianna used the results of full genetic analysis, combined with ancient geography, ice cap conditions and changes in Antarctic ocean currents to determine Deduction. Genome wide analysis resulted in the evolutionary tree of penguins. King penguins and emperor penguins separated from everyone long ago… I’m sorry to find out that at the molecular gene level, the evolution of penguins is towards the Antarctic. Developing adaptability to both the equator and the equator, the penguins’ hometowns are actually Australia and New Zealand, where the sea surface temperature is 9 degrees. The evolutionary path of penguins starts from Australia and New Zealand (I) –> Antarctica (D) — > Antarctic Peninsula (C) –> South America (A) Scientists used satellites to observe penguins in Antarctica and found that global warming has a great impact on the lives of penguins. Although Adélie penguins live in a world of ice and snow Antarctica, but in order to protect the precious eggs, they always find places without ice and snow to build nests and lay eggs. In 2016, scientists discovered that the places where Adélie penguins were used to nesting are now beginning to melt due to climate warming. Drowning the eggs and chicks in the Adélie penguin nest. Moreover, climate change has also caused changes in the distribution of the food of the Adélie penguins, Antarctic shrimp. For various reasons, the Adélie penguins have begun to move and search for A possible place to survive. Halley Bay, the second largest territory of emperor penguins, is at the top of the picture. It has been unable to hatch penguin babies for three years. A large number of emperor penguins moved to Dawson-Lambton at the bottom of the map to give birth to children. Ad is preparing to move. Emperor penguins are preparing to move. In 2019, scientists also discovered that Halley Bay, the second largest emperor penguin territory in Antarctica, has experienced stronger winds and thinner ice since the El Niño phenomenon in 2016. This situation has continued for three consecutive years. There was no improvement, and no penguin babies might be hatched. This was an unprecedented situation. However, the village next door, Dawson-Lambton, began to be crowded with penguins, and emperor penguins also began to migrate. The two cities of emperor penguins were written. Story. Currently in existence, the closest relatives to penguins, the flying bird relatives, the guinea pigs. From the formation to the present, the earth has gone through several extreme climate changes. Penguins have spent more than a million years adapting to different environment. From the beginning of human civilization to the present, the rate of climate change caused by human activities has been so fast that many species have difficulty adapting through evolution, and penguins are one of them. Now, penguins have begun unprecedented pioneering actions. Can the changes of penguins keep up with the speed of global warming? Or, are we saying goodbye to penguins once more? # Scientist’s Penguin # Where is the penguin’s hometown # crooked road penguin # penguin ancestors # humanbird penguin # penguin world The streak of articles #胜文Brother was shot once more #Penguin Great Migration #Penguin Two Cities Story #Climate Change #Global Warming #Antarctic Ice ——————- ——- —————————-【Listen to the Comedy Science Podcast: Sky in the Wall】Apple Podcast: FM: Comedy Science Articles: Sky in the Wall]Instagram:
