They go through a dramatic metamorphosis - but still remember the knowledge gained. I bet when you learned about a caterpillar's metamorphosis into the butterfly stage, you were surprised. After all the animal basically gets a new body. And surprisingly, scientists at Georgetown University found that animals remember things they learned in their early stages of development.

Our perceptions and knowledge about these animals have changed a lot since the discovery of the first fossils and continue to change in light of new findings. Our perception and understanding of dinosaurs has changed significantly since the first fossils were found - and they continue to change as new discoveries emerge.
Flossing or flossing is critical to the health of your teeth as they reach places not reached by the brush. But what is the correct sequence? Thread the wire before or after brushing? While there is no scientific evidence for what is best, we recommend flossing before brushing.
Sperm, male sex gametes, are produced in the testicles. The testicles are in the scrotum, which looks flaccid and slightly wrinkled. It is important that they are located outside the abdomen because sperm are produced at a lower temperature than the rest of the body.
We already know the "common" talents of animals, such as the strength of lions or the speed of cheetahs. But did you know the ability of spiders to float and skydive? Check out the list below with 15 animals we know and their unknown talents. Penguins cannot fly, but can jump up to two meters in the air.
You have probably heard that breast milk is amazing. Doctors, nutritionists, magazines, blogs and even strangers love to inform a pregnant woman of all the millions of benefits of breastfeeding, which, by the way, has been confirmed by many scientific researches. The funny thing is, despite all this, scholars are still trying to understand exactly how this magical liquid works.
Science has certainly improved our understanding of the world enormously, but there are still many things that just don't seem to explain and continue to intrigue scholars for decades. How ... 10. Cows Always Face North or South While Eating When a team of scientists analyzed thousands of Google Earth satellite images of cows (don't ask me why), they discovered a detail that went unnoticed for millennia: animals always turn to the pole magnetic north and south while eating or resting.
Genes do what we are, and sometimes they can make amazing combinations. Meet 10 rare genetic mutations that give superpowers. Compared to many other species, all humans have incredibly similar genomes. However, even slight variations in our genes or environments can cause us to develop traits that make us unique.
Normally people confuse these three animals, although they have many differences in morphology, habitat and behavior. What they have in common is that they are classified as anuran, a name given to non-tailed amphibians. Contrary to popular belief, frogs and tree frogs are not female frogs.
In nature, some beings may play various roles in different food chains. When we eat an apple, for example, we play the role of primary consumers. Already eating a steak, we are secondary consumers, because the ox, which eats the grass, is primary consumer. Many other animals also have varied diets.
Pantanal Mato Grosso Located in the Midwest region of Brazil, it comprises part of the states of Mato Grosso and Mato Grosso do Sul. Area that represents the most important and known wetland in the world (largest floodplain in the planet), with amazing rates of animal biodiversity. It is influenced by several ecosystems, such as the cerrado, the Amazon rainforest, the Atlantic forest, as well as the cycles of drought and flood, and high temperatures.
Brazil has a great diversity of ecosystems. Almost all of its territory is situated in the tropical zone. Therefore, our country receives a great deal of heat all year round, which favors this great diversity. See the map below for examples of the main ecosystems found in Brazil.
What does ecology study? The Amazon forest has a rich vegetation. And the variety of animals is also huge. It is estimated that in a single tree of the Amazon rainforest can be found more than a thousand different species of insects. In fact, if we gather all the rainforests of the planet, we will see that there are more than half of the living species in them.
In an ecosystem, living beings relate to the physical environment as well as to one another, forming what we call ecological relationships. Ecological relationships occur within the same population (that is, between individuals of the same species), or between different populations (between individuals of different species).
The animals that have cheloma are called cheloma. All chords are chelomated, as are mollusks (slugs, oysters), annelids (earthworms) and echinoderms (starfish, sea urchins). There are triblastic animals in which the mesoderm delimits one part of the cavity, the other part being delimited by the endoderm.
Tip 9 - What's wrong with drinking tap water? Know that she is well treated before arriving at your home. Then install a scrubber on the tap and forget about the annoying carboys. Consumption of bottled water involves transportation in diesel vehicles. Need I say more? Tip 10 - One of the major problems of water pollution comes from the habit of throwing frying oil into the plumbing.
Tip 3 - Do you have a cruder attitude than throwing can or other waste through the car window? The punishment for this gaffe is guaranteed: the waste dumped on the street is dragged by rain, clogs manholes, reaches rivers and dams, causes flooding and impairs the quality of the water we consume. Tip 4 - Standby and daytime appliances are another invention in the name of comfort.
The wing of a bird, the anterior fin of a dolphin and the arm of a man, although very different, have very similar bone and muscle structure. The similarity can be explained by assuming that these beings had common ancestors from which they inherited a basic plane of body structure.
Darwin was influenced by the works of famous scientists, such as astronomer John Herschel (1792-1871) and naturalist and traveler Alexandr Humboldt (1767-1835). The latter was responsible, according to Darwin himself, for the impulse to travel to unknown lands on scientific expeditions. The work of geologist and friend Charles Lyell (1797 - 1875) also marked Darwin's study.
