Specifically speaking of transitions from aquatic to terrestrial life, the major evolutionary trends involve developing survival instincts and functions to survive on land. Frogs are a perfect example. After going through a number of embryonic stages, a tadpole is created. Due to their specialized organs, muscular system, and nervous system, tadpoles are able to swim. As the larva matures and goes through metamorphosis, it becomes a frog capable of both swimming and hopping. Although a tadpole evolves into a frog, there are many differences between the two. A tadpole only swims and feeds on plankton whereas a sexually mature adult frog can swim and hop and has a diet consisting of insects and worms. During metamorphosis, tadpoles develop
Adaptations in terrestrial environments involve the structural and functional qualities of the organism, to achieve the adequate intake of oxygen and other essential substances for the animal to survive, the evolution of more complex anatomical structures were required. Gravity is stronger on land than water, which means terrestrial organisms have to be more structural than aquatic organisms. Also, the balance of gas exchange with water loss is a key feature to survive in land. For example plants, when doing photosynthesis require carbon dioxide and water to produce oxygen, at the end of this process a lot of water is lost and terrestrial plants have to compensate the water being lost and the water taken from soil. Furthermore, the dispersal of gametes by wind or other animals have helped plants reproduce in large amounts and create varieties of species of the same kind. Short-term weather patterns as well as long-term climate conditions based on precipitations, temperature, wind, humidity as well as other factors are survival obstacles that organisms in land have to adapt to live; endothermic organisms have to maintain a constant internal
Evolving is when something changes and develops as time progresses by displaying growth or formation. Evolution has never ended since the absolute origin of life, and will maintain to happen until life is expired for each and every one. Adaptation is required for survival , and to adapt is to remodel for a suitable outcome to the situation or environment. Life in the 17th century and 1600 was an immense imprint for the record of what is life here and now; the changes it went through to remain. The New England and the Chesapeake region were both settled largely by people of English origin , they evolved into two distant societies because of motives, economics and religion/social.
“Hop-Frog,” composed by Edgar Allen Poe, begins as a classic fairy tale that many are familiar with, but “Hop-Frog” takes a dark and brutal turn as the jokes and humiliation reach a certain extent. Poe introduces Hop Frog and Trippetta first as victims of the king and his seven cabinet council men; due to their physical features and status as the king’s slaves for entertainment and humor. As the reader proceeds to read the great detail given by Poe, the reader begins to understand the abnormality in Hop Frog’s thinking and actions when he becomes fed up. Hop-Frog has no intention in causing any harm or brutality, but there needs to be an end to the torture and embarrassment caused to Hop-Frog and Trippetta. Hop-Frog’s act of revenge is the act of a sane man, but this is due to the abuse of power and authority by the king and his seven council men which lead to the devastating end.
it has smooth or slimy skin, frogs tend to lay eggs in clusters. Unlike Toads, Toads have stubby bodies with short hind legs, for
There are several major trends that developed in the vertebrate group that has allowed the transition from aquatic to terrestrial life. Some of these trends are improved respiration, protective body covering, and more efficient ways to reproduce. The adaptations that have allowed the transition from aquatic to terrestrial life are: Jaws, lungs, jointed vertebrate limbs, water tight skin, amniotic egg for reproduction. In birds and mammals another adaptation that has evolved is that they are endothermic meaning they generate internal heat.
In "Hop-Frog," the eponymous
Biological evolution itself is the change in characteristics of living organisms over generations. Evolutionary theories suggest that all organisms alive today share a common ancestor. As unlikely as it sounds, evidence has been discovered proving this theory (relations from a spider to a monkey).
This allows us to see, up close, the transformation of animals. What was once isolated to only the sea, evolved into something that could now dwell on land as well. Throughout the course of history, more and more evolutionary traits will occur allowing different species to prosper where they once could not.
In Poe’s short stories we can often find characters very similar to Poe himself. One of the most prominent and easiest ones to see is in Poe’s short story “Hop-Frog.” In this story we can see some similarities in the main character Hop-Frog, and Poe himself. Hop-Frog is a court jester who is a dwarf, he and his very dear friend Trippetta, who is also a dwarf, are from a far-off foreign land. Trippetta was very beautiful and fulfilled many duties for the king; such as planning masquerades. Hop-Frog is a dwarf that has something wrong with his legs, to where he cannot move and walk as other men do; however, he has an extraordinary amount of upper body strength. Hop-Frog can climb almost anything with ease. Poe and Hop-Frog are not alike in this respects, but they are alike in the sense of their alcohol intake. Poe was never able to drink alcohol, even one sip of alcohol would make Poe so delirious, that he did not know what was going on (Edgar Allan Poe). The same is very much true for Hop-Frog.
In the story “Master Frog”, Master Frog is born a frog but lives a normal life. This story takes place in ancient Vietnam. When Master Frog is a child his mom, Giang Dung, goes to the school and makes sure Master Frog gets education because he is very intelligent. After he is a grown frog, Master Frog goes to the palace and asks for Kien Tien’s hand in marriage. At first the king says, “We have carried this joke far enough, take this presumptuous creature out of my sight at once and execute him.”
Overtime, a population may grow, develop and interact with its environment. During that interaction, different mechanism such as evolution may occur. Evolution which is the change in allele within
The definition of biological evolution varies from studied biological aspects . Some definitions are common in biology books , among others : the evolution of living things is the changes experienced by living beings slowly over a long time and lowered , so that over time can form new species : evolution is the change in frequency genes in populations over time ; and adaptive evolution is the change in the character of the population from time to time . Evolution has been uniting all branches of
Tadpoles are really cool looking but there faces are so ugly. Tadpoles are really small you can't really see them that much they have to grow so to see them.The tadpoles have big eyes there eyes help them to see. Tadpoles are really not smart when there young but when they get a little order there smart. People use tadpoles for fishing. Alot of animals eat tadpoles like snakes, fish, and other things.When the mother gives birth to the frog the mother lives and goes somewhere alse.Then the mother comes back and lies more .
Frogs, toads, caecilians, and salamanders are the members of the class Amphibian (amphi- meaning “on both sides” and bios- meaning “life”). These members always require water for reproduction. Most Amphibians undergo metamorphosis, which is a usually degenerative pathological change in the structure of a particular body tissue. And, in the case of Amphibians, it is the changing of a tadpole into
Animals and plants had to change or evolve due to environmental pressures. Over millions of years the conditions on the Earth have changed tremendously, the environmental conditions we have now are very
