Natural Selection Natural selection is a theory created by Charles Darwin. This theory explains that organisms that are more adapted to their habitat live longer and are more likely to pass on their traits through reproduction. For example‚ a green tree frog in a green rainforest would be more adapt than a gray tree frog. A green tree frog has the potential to blend in with the green surroundings‚ but the gray tree frog would be easily spotted by a predator and eaten due to its color and inability

Natural selection is Charles Darwin’s most famous theory; it states that evolutionary change comes from genetic variation in each generation and the survival of individuals with different combinations of these variable traits. Organisms with such characteristics that increase their probability of survival in their environment will endure and possess more opportunities to reproduce. Over time these traits are passed on to their offspring and proliferate through the population. Darwin’s innovative

Charles Darwin was an Englishman who was fascinated with nature‚ otherwise known as a naturalist. Darwin began a long voyage to explore the natural world. He collected fossils and sketched several animals. From this‚ he created the theory of evolution. A common ancestor is the most recent ancestral form or species from which two different species evolved. Evolution is certainly not something everyone agrees on. Millions of people have made theories‚ which are explanations of a part of the natural world

useful to certain members of many different species as shown by Darwin ’s Theory of Sexual Selection. They enhance the ability of the individual to obtain mates and are therefore very important in the reproductive and evolutionary success of many animals. It is first necessary to understand the basics of Natural Selection before being able to show how Sexual Selection leads to extravagant traits. The main idea behind natural selection is that living organisms change and adapt in order to enhance their

have thousands of species (flora‚ fauna and organisms) of all different features‚ family and history of growth and survival. The theory of natural selection introduces the theory of survival of the fittest flora and fauna‚ where one survives only if it is fit for the nature. The theory of natural selection in easy terms is that the one who fits is the one who stays. Darwin says the one that fights against and with the nature for its survival is the one that are still present

have been many theories that explain how evolution occurred. Charles Darwin‚ on the book Origin of Species‚ spoke about how traits are passed on from generations to generations by natural selection. In addition‚ he stated how there are four objections to the theory of natural selection‚ how species can win the struggle for existence through natural selection‚ and how the origin of species challenges religion. Central to the theory of evolution‚ is natural selection. Evolutionary theory was developed

Charles Darwin formulated his idea of natural selection at age thirty‚ he published his work years later for fear of the controversy that would overshadow his work. Darwin’s theory of natural selection challenged the normal science of the time: the belief that a divine creator created all the species‚ which were incapable of change. Darwin’s theory also challenged the overarching authority of the time: the church‚ which supported the ideology of God creating a static species. Furthermore‚ Darwin lacked

Acrophobia is an irrational fear of heights or high places. Many people dislike heights‚ but someone with a clinical case of acrophobia can have intense emotional and physical responses at just the thought of being in a high place. Acrophobia is simply a severe fear of heights. Now being afraid of heights is a common and sometimes appropriate feeling. But the phobia part kicks in when you feel afraid in a safe environment such as inside a skyscraper. Acrophobia is treated with graded exposure therapy

STATED CLEARLY: EVOLUTION AND NATURAL SELECTION (TRANSCRIPT) What exactly is evolution? In biology‚ the theory of evolution doesn’t exactly tell us how life began on Earth‚ but tells us how life‚ once it came into existence‚ diversified into the many incredible forms we see now and in the fossil record. It also helps us make sense of the way in which modern creatures continue to adapt and change today. In biology‚ evolution can be defined as: ‘Any change in the heritable traits (those are physical
