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

Symmetry Symmetry has two meanings. The first is a vague sense of harmonious and beautiful proportion and balance.[1][2] The second is an exact mathematical "patterned self-similarity" that can be demonstrated with the rules of a formal system‚ such as geometry or physics. Although these two meanings of "symmetry" can sometimes be told apart‚ they are related‚ so they are here discussed together.[2] Mathematical symmetry may be observed * with respect to the passage of time; * as a spatial

Stem cells -are biological cells found in all multi cellularorganisms‚ that can divide (throughmitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In mammals‚ there are two broad types of stem cells: embryonic stem cells‚ which are isolated from the inner cell mass of blastocysts‚ and adult stem cells‚ which are found in various tissues. In adult organisms‚ stem cells and progenitor cells act as a repair system for the body‚ replenishing

Chapter 10 Foundations of Genetics Lecture Notes 1 Foundations of Genetics Mendel and the Garden pea The father of modern Genetics is Gregor Mendel. Gregor Mendel (1822-1884) was an Austrian monk who lived in a monastery where the experiments with the garden pea were performed. Mendel’s work with the garden pea was the fundamental study which unveiled the laws that govern genetics and heredity. Mendel was the first to use the scientific method in a very systematic and analysed his results
