What is evolution? Over time, animals and plants change and evolve because offspring have slightly different characteristics to their parents. Living things born with adaptations that make their lives easier in specific habitats are more likely to survive;the process of advantageous adaptations being pa...
What are evolutionary adaptations? What is gene theory? What is genetic convergent evolution? What does natural selection cause? Did Darwin study embryology? Was Charles Lyell an evolutionist? How did speciation in Darwin's finches occur?
What are the two main types of genetic drift? What role does evolution play in hereditary diseases? What does parallel evolution result in? Adaptations result from interactions between organisms and their what? What is a common cause of stabilizing selection?
The mid-19th century was marked by a new theory, that of Charles Darwin, who based his theory of evolution on the concepts of natural selection and survival of the fittest. According to the Charles Darwin book, _On the Origin of Species_, published in 1859, the process of natural...
Adaptation refers to evolutionary changes in organisms for better survival over generations. 9 How is acclimation defined? Acclimation is the short-term physiological response of an organism to changes in its environment. 8 Do adaptations affect future generations? Yes, beneficial adaptations are passed...

This essay examines the dominant terms currently in use in studies of Shakespearean rewritings (adaptation and appropriation), reviews their recent critical histories, and considers their theoretical advantages and drawbacks. The essay concludes that at the current moment, both terms are apt and useful...
So molecules like this ended up on Earth. In fact, what we call meteorites are pieces broken away from comets and asteroids that came in our atmosphere and left their extra-terrestrial organic matter on the surface of primitive Earth.这样的分子最终来到了地球上。事实上，我们所说的陨石是来自彗星...
Species that are linked through convergent evolution oftentimes look very similar. However, they are not closely related on the tree of life. It just so happens that their roles in their respective environments are very similar and require the same adaptations in order to be successful and reprodu...
Natural selection Adaptations can lead to evolution What is an adaptation? A mutation in DNA that leads to a special trait or behavior that help an organism survive better in its environment, Natural selection THE ORGANISM: Biston betularia is the scientific name for a moth that lives in foreste...
