run into several problems with taxonomy‚ or the classification of species. A science that can help in solving classification issues is embryology. In chapter thirteen Darwin discusses how in several different species‚ the embryos actually resemble each other‚ and start to resemble their distinct species as the fetus matures. This change seen in the embryos actually represents the emergence of divergent characteristics in these species. If a modification of an organisms is seen as a specific period

invertebrates‚ fish and amphibians‚ on to reptiles‚ birds‚ and eventually land mammals‚ species have evolved in huge leaps and bounds in the millions of years that our planet has been in existence. We have moved out of the water and onto the land‚ we have developed brains and nervous systems‚ highly advanced survival instincts and social and behavioral traits that did not exist millions of years ago. Species have evolved to become more diverse and more complex through a number of different biological

With the publication of Darwin’s groundbreaking work‚ the Origin of Species‚ a new group of people‚ the Social Darwinists‚ applied the theory of natural selection to social hierarchy. A most notable Social Darwinist‚ Herbert Spencer‚ coined the term “survival of the fittest”‚ implying that people in higher social groups

In 1859‚ Charles Darwin published The Origin of Species. It had no greater effect on anyone other than his cousin‚ Francis Galton‚ who was rather interested in the theory of natural selection. He began to conduct investigations into the importance of heredity factors in the physical and mental makeup of a person. Darwin and Galton

Natural selection was a fundamental idea formed by Darwin that living things evolve gradually from generation to generation. Darwin argues that all living species come to historical process through a historical process involving random changes. Through natural selection living things have acquired to behave in ways that provide the promotion of survival and reproduction. What happens in natural selection is that the organisms with favorable traits that help them survive live long enough

would be no progression of species complexity over time. There are species that have existed relatively unchanged for millions of years referred to as living fossils. This is not evidence against evolution‚ only evidence that the traits of those particular species have been very successful for survival over a long period of time. 2. Each continent and even groups of islands contain unique species of plants and animals. If there was no evolution‚ there would not be unique species on every continent as

Introduction According to Darwin’s Origins of Species that was published in 1859‚ in the process of nature selection and evolution‚ the weaker ones will be unavoidably weed out by the stronger ones. His theory had caused philosophers‚ sociologists‚ and others began to adopt the idea that human society had also evolved. One of the most well-know theory inspired by Darwin is Spenser’s social evolution‚ popularly known as the Social Darwinism‚ which centers around the idea of " Survival of the fittest"(Wikipedia
