Dinosaurs ruled the land, the ocean, and the sky for about 165 million years. Rex Tyrannosaurus hunts its prey with 50 to 60 banana-sized teeth. The 55-foot dragon from nose to tail frightened the ocean and ate everything they could catch. But 66 million years ago, the world's climate changed dramatically. Suddenly, the earth became colder and darker. All dinosaurs-except...

Cosmological observations from the past 50 years show that 85% of the matter content in our Universe is made up of non-luminous matter - commonly known as dark matter(DM). Characterizing the properties of DM is a major open question in physics today. Numerous experiments are underway to directly detect DM. The DEAP-3600 (Dark matter Experiment using Argon Pulse-shape discrimination) collaboration...

Introduction Throughout history a number of alternate theories of evolution have been proposed by equally intelligent scientists, most notably the theories of Jean Baptiste Lamarck, Charles Darwin and Alfred Russel Wallace. As with various theories, many tend to raise the question as to which theory has had the greatest contribution to modern evolutionary theories. Evolution is the one of the...

Specific interpretations in Darwinâs theories of evolution pose challenges to modes of proceeding within feminist critique. Since the conception of his theories of natural and sexual selection in the mid to late 19th century, it has been âeasier to imagine Darwinism and feminism as adversaries rather than alliesâ. Women authors in the 19th and early 20th centuries did lots of...

As scientists, mathematicians and other incredibly smart people started looking up at the night sky, they wondered - why is the universe of the shape that it is? What gives solar systems and galaxies their form, why donât they just scatter and fly away? These questions came up as soon as the scientists at NASA started measuring the gravitational impact...

Dark matter is an incredibly elusive force which is necessary for many modern theories that describe the movement of galaxies and â effectively â all of the major elements of the universe. One of the reasons that dark matter has arisen as a theory is the fact that when we observe certain galaxies, they have much more kinetic energy then...

Dark Matter accounts for 84% of all the matter in the universe. The remaining 16% is ânormalâ (also called baryonic) matter, comprised of every single planet, star and galaxy in the visible universe. Dark Matter earned its name because it does not interact at all with the Electromagnetic Force. This means it does not absorb, emit or reflect visible light,...

Dinosaurs first appeared in the latter half of the middle Triassic 230-240 million years ago; they were originally bipedal carnivores, and quite small relative to the colossal dinosaurs that proceeded them. These primitive dinosaurs rapidly evolved into the two major clades we know of today; Ornithischia and Saurischia, Saurischia being comprised of both Sauropoda and Therapoda. Saurischia makes up all...

Evolution is the development of life on earth. This process began billions of years ago and is continuing to this day. Evolution tells us how the enormous diversity of life could develop. It refers to any change in the distribution of alleles within a population over time. In the early 19th century Jean-Baptiste Lamarck (1744â1829) was the first to fully...

Much debated topic among psychologist are always, whether our personality and behaviour are governed by nature or nurture. Evidence from various psychologistsâ study have very much agreed that both also can influence and shape who we are. But to what extent, or which is more important is still an ongoing debate. The following contents of this essay will describe about...

Introduction The dialogue between scientific theories and religious beliefs has persisted as a central theme in intellectual discourse. Among the most debated topics is the relationship between the theory of evolution and Islam, which presents a complex intersection of scientific inquiry and theological interpretation. Islam, as a major world religion, offers a rich tapestry of beliefs and interpretations that engage...

Plato to Darwin to DNA highlights the different understandings of our natural world throughout history. Not only is the reader able to get a detailed view of each periods method of research and development of theories, but also is able to compare them with one another. The âscientific processâ as we know today was incredibly different in the past, and...

Introduction (200 words) Natural selection, a key concept in evolutionary biology, profoundly shapes the diversity of life. This principle, first elucidated by Charles Darwin, explains how species evolve and adapt through generations. It is the process by which traits that enhance survival and reproduction become more prevalent within a population, leading to the gradual evolution of species. This dynamic reflects...

Introduction Mycoviruses, the viruses that infect fungi, represent a fascinating and relatively unexplored domain within virology. Unlike their plant and animal counterparts, mycoviruses are predominantly cryptic, often not causing overt symptoms in their fungal hosts. This attribute has historically rendered them obscure, with their discovery and study lagging behind other viral forms. However, increased awareness of their potential roles in...

An aspect of biology that interests me is the evolution of humans over many hundreds of years. Human evolution began six million years ago in Africa. This has been proven countless times by evidence such as fossils of human remains which can be dated back to many million years ago. Our first ever relative was a fish that existed 400-350...
