Speciation is the evolutionary process by which new species arise. It occurs when populations of a single species become reproductively isolated and evolve independently. Types of Speciation: 1. Allopatric Speciation (Geographic Isolation): Occurs when a population is physically separated by a barrier such as mountains, rivers, or oceans. Example: Darwin’s finches evolved into different species … Read more
Charles Darwin traveled on the HMS Beagle from 1831 to 1836, studying diverse species in South America, the Galápagos Islands, and other locations. His key observations included: 1. Variation in Species: Darwin noticed that finches on different Galápagos Islands had different beak shapes, suited to their specific diets. Some had long, pointed beaks for insects, … Read more
Darwin’s theory of evolution by natural selection explains how species change over time due to differences in survival and reproduction. The key principles of this theory are: 1. Overproduction: Organisms produce more offspring than can survive. For example, a frog lays hundreds of eggs, but only a few tadpoles reach adulthood. 2. Variation: Individuals in … Read more
Selection is a fundamental mechanism of evolution, as it determines which individuals survive, reproduce, and pass on their traits to the next generation. It plays a major role in shaping the genetic structure of populations over time. There are two main types of selection: 1. Natural Selection: Proposed by Charles Darwin, natural selection explains how … Read more
