The elementary idea is that whenever there will be change, the organisms which are best suited to the environment or circumstances will thrive, these organisms will be developed successfully in the new circumstances. Those organisms that are not suited ideally or less suited, will not be able participate in competition; they will not be developed in the new environment. Darwin observed this in some
In simple words is just the rate of reproduction and mortality. Those organisms who successfully adapt to the environment survive and reproduce organisms able to adapt and survive too. The purpose of this activity is to see how natural selection happen and see which animals evolve and adapt to their environment in order to survive. Animal struggle for existence,
Topic 1 Discuss some of the ways that Darwin’s theory of natural selection was transformative to his society. Natural selection is “the process whereby organisms better adapted to their environment tend to survive and produce more offspring.” (What is natural selection, n.d.) In other words the strongest genes are passed to their offspring.
Natural selection is a force of nature that is a catalyst to forever changing variations in species of plants and animals. Pertaining to the article, "Darwin and Natural Selection" by Dr. Dennis O'Neil, the Galapagos Islands helped Darwin to understand the idea of evolution. Darwin identified thirteen different species of finches that differ from beak size and shape. The term used for this variation today is called adaptive radiation; where different populations of the same species develop different characteristics due to contrasting environments. Moreover, Darwin realized the beak varieties were apparent to the differing diets of each population of finches.
The main aspects of Darwin’s Natural selection is about living organisms with suitable and inheritable traits for the survival and reproduction of new species. Offsprings that inherit better traits have an improve the population. For example; a giraffe will a long neck because it eats from tall trees. It is because of the tall trees( environment) that the Giraffe eventually evolves long neck as a mechanism for survival. By leaving an impact on their physical and social environment, organisms may affect the evolution of their own descendants, quite apart from changing the conditions for themselves.
Organisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring. Birds and caterpillars have a predator-prey
“Thank You, Ma’am”, by Langston Hughes, is a tale about a young lad named Roger who attempts stealing to provide for himself, when instead he learns a valuable lesson. “The Necklace”, by Guy de Maupassant, is a story about a selfish woman named Mathilde and her husband, with a surprising twist at the end of the short story. These fables are going to be used to compare and contrast the messages of morality, socio-economic status, and family. On the topic of morality, Roger from “Thank You, Ma’am” and Mathilde from “The Necklace” are different.
With respect to variations that are advantageous to survival, he notes that a slim wolf is more likely to run faster, catch prey and escape from predators. He also states that plants with attractive petals and sweet nectar is more likely to attract more insects that will serve as agents of pollination for that plant. Regarding variations that are useful for sexual section but not directly useful for survival in nature, he mentions brightly colored feathers in male birds and the ability to perform the mating call well. These traits, although useful for finding mates and reproducing might not be useful for escaping from prey. On the issue of isolation and natural selection, Darwin talks about organisms on islands and the importance of the weaker organisms dying out leaving those who are best suited for the environment to reproduce and ensure longevity of the species.
This process allows the strong and more adaptable animals to survive and carry on their genes to their children. There are many examples of natural selection all over the world; however, the giraffe is a one of the best examples of this process. Giraffes originally had much smaller necks then they do today. This was because the earlier giraffes had the
Since Darwin first suggest his concepts about biological evolution and natural selection various lines of research from many different branches of science have produced evidence supporting Darwin’s belief that biological evolution arises partly due to natural selection. The environment selects certain species because of advantageous characteristic and ability to adapt to the environment in compared to other species. Fossil record illustrates this through old rocks animal remains showing simple to complex evolving. One area is comparative anatomy, which has shown similarities in structures of different living organisms, such as the skeletons of humans, bats cats, and bats. Even though these species live in different climax and environment
This explains that organisms that are better adapted to their environment tend to survive longer and transmit more of their genetic characteristics to succeeding generations than do those that are less well adapted (Farlex,
An example would be the cactus and the euphorbs, both plants are found in deserts but just in different parts of the world. Both plants adapted parts that were required to live, photosynthetic stems for water storage, spines that protect the plants, and reduced leaves, Different plants most likely lived there but because of the change in climate to a very dry climate, only the plants that bore adaptation were able to survive the dry environment. Selection for resistance can possibly occur if a population is able to survive a treatment with insecticide. The population that survives will be able to pass on their resistance traits to the offspring. The individual that does not survive dies and soon the species will become extinct.
Only the offspring with certain traits that were suitable with the environment survived. This led him to believe that species evolve from a common ancestor because he saw that many organisms had similar traits and that they eventually accommodate to their surrounding
Imagine what would happen if we lived in a world where water was kept 8 feet off the ground and there was absolutely no way you could get it if you weren’t tall enough. Most likely, the short people would die off. The taller ones would multiply, and before long, instead of a population of people of all sizes, you would have a population of only tall people. Living things that are best suited, or adapted, to their environment survive and multiply. Those that are not, are unable to survive.
Therefore, for individuals to survive and reproduce it traits need to be selected by natural selection and the genes that produces that traits have to be well adapted to its
