Was Darwin Wrong? By David Quammen Evolution by natural selection‚ the central concept of the life’s work of Charles Darwin‚ is a theory. It’s a theory about the origin of adaptation‚ complexity‚ and diversity among Earth’s living creatures. If you are skeptical by nature‚ unfamiliar with the terminology of science‚ and unaware of the overwhelming evidence‚ you might even be tempted to say that it’s "just" a theory. In the same sense‚ relativity as described by Albert Einstein is "just" a theory

1 What is science? The word “science” probably brings to mind many different pictures: a fat textbook‚ white lab coats and microscopes‚ an astronomer peering through a telescope‚ a naturalist in the rainforest‚ Einstein’s equations scribbled on a chalkboard‚ the launch of the space shuttle‚ bubbling beakers …. All of those images reflect some aspect of science‚ but none of them provides a full picture because science has so many facets: These images all show an aspect of science‚ but a

Evolution of Whales Whales have evolved dramatically to adapt to life in the water as they started out as typical land animals. It has taken 12 million years for the modern whale to become as we know it. They had feet and legs suited for walking on land. They also had long skulls and carnivorous teeth‚ these whales evolved nostrils that were positioned further and further back along the snout. This trend has continued into living whales‚ which have a "blowhole" (nostrils) located on top of the

After perusing the article “Easter’s End (1995: 62-69) by Jared Diamond”‚ I have learnt that the past Polynesian civilization on Easter Island was severely dismantled due to introduction of foreign species‚ overpopulation‚ continued deforestation and extraction of natural resources. The author implied that we might succumb to a similar consequence if our ecological hazards continuously being ignored. This article is mainly about the factors that cause the extinction of the former civilization on

Microraptor Gui is 77 cm in length and has four wings. What’s different about this species is that it has a wing on each of its hind limbs. On January 23 in the issue of the journal Nature‚ Xu Xing‚ a paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing‚ China‚ says that in the the species was an early ancestor of birds that most likely used its feathered limbs‚ along with its long feather-fringed tail‚ to soar from tree to tree.

Science is an organized body of knowledge supported by observation and experimentation‚ derived from the natural phenomena of the entire material universe. Biology had flourished a great deal in ancient India. Various systems of classifying animals and plants were developed‚ for example Jeevaj (Viviparous) animals that give birth to young one‚ Andaj (Oviparous) animals that lay eggs‚ etc. Cultivation of rice was first introduced in India. It is estimated that more than 1000 varieties of rice had

Introduction The Forest Hill Formation is a geological area that mainly stretches from west-central to southeastern Mississippi‚ but thins right at the border of and barely touches Clarke County‚ Alabama (Echols‚ et al.‚ 1893). Geologist Ephraim Nobel Lowe originally proposed the name Madison Sands for this formation‚ due to the fact that he had studied it in Madison County‚ Mississippi. The name was later changed to Forest Hill by Charles Wythe Cooke. The Forest Hill Formation overlies the Red
