The Academy's Evolution Site
Biological evolution is one of the most important concepts in biology. The Academies are involved in helping those interested in the sciences learn about the theory of evolution and how it is permeated in all areas of scientific research.
This site provides students, teachers and general readers with a variety of learning resources about evolution. It also includes important video clips from NOVA and WGBH produced science programs on DVD.
Tree of Life
The Tree of Life is an ancient symbol that represents the interconnectedness of life. It appears in many religions and cultures as a symbol of unity and 에볼루션카지노 love. It can be used in many practical ways as well, including providing a framework for understanding the history of species and how they respond to changing environmental conditions.
The first attempts to depict the biological world were based on categorizing organisms based on their physical and metabolic characteristics. These methods are based on the collection of various parts of organisms, or DNA fragments, have significantly increased the diversity of a Tree of Life2. However, these trees are largely made up of eukaryotes. Bacterial diversity is still largely unrepresented3,4.
In avoiding the necessity of direct observation and experimentation, genetic techniques have made it possible to represent the Tree of Life in a more precise way. Particularly, molecular methods enable us to create trees using sequenced markers, such as the small subunit ribosomal RNA gene.
The Tree of Life has been greatly expanded thanks to genome sequencing. However there is still a lot of biodiversity to be discovered. This is particularly true for microorganisms that are difficult to cultivate and which are usually only present in a single sample5. A recent study of all known genomes has produced a rough draft of the Tree of Life, including numerous archaea and bacteria that have not been isolated and which are not well understood.
The expanded Tree of Life is particularly beneficial in assessing the biodiversity of an area, assisting to determine whether specific habitats require protection. This information can be utilized in a variety of ways, such as finding new drugs, battling diseases and improving crops. The information is also useful to conservation efforts. It helps biologists discover areas that are likely to have cryptic species, which could have vital metabolic functions and are susceptible to changes caused by humans. While funding to protect biodiversity are important, [empty] the best method to preserve the world's biodiversity is to empower the people of developing nations with the necessary knowledge to act locally and promote conservation.
Phylogeny
A phylogeny (also called an evolutionary tree) shows the relationships between different organisms. Using molecular data, morphological similarities and differences, or ontogeny (the course of development of an organism), scientists can build a phylogenetic tree which illustrates the evolutionary relatds predict the duration and rate at which speciation occurs. This information can help conservation biologists decide which species they should protect from extinction. Ultimately, it is the preservation of phylogenetic diversity which will create an ecosystem that is complete and balanced.
Evolutionary Theory
The main idea behind evolution is that organisms develop distinct characteristics over time due to their interactions with their environment. Many scientists have developed theories of evolution, such as the Islamic naturalist Nasir al-Din al-Tusi (1201-274) who believed that an organism could evolve according to its own requirements, the Swedish taxonomist Carolus Linnaeus (1707-1778), who created the modern hierarchical taxonomy, as well as Jean-Baptiste Lamarck (1844-1829), who suggested that the use or absence of certain traits can result in changes that are passed on to the next generation.
In the 1930s and 1940s, theories from various fields, such as natural selection, genetics & particulate inheritance, were brought together to create a modern evolutionary theory. This defines how evolution is triggered by the variation of genes in the population and how these variations alter over time due to natural selection. This model, called genetic drift or mutation, gene flow, and sexual selection, is the foundation of current evolutionary biology, and can be mathematically described.
Recent discoveries in the field of evolutionary developmental biology have shown that genetic variation can be introduced into a species by genetic drift, mutation, and reshuffling of genes during sexual reproduction, and also through migration between populations. These processes, as well as others such as directional selection or genetic erosion (changes in the frequency of the genotype over time) can lead to evolution that is defined as changes in the genome of the species over time and also the change in phenotype as time passes (the expression of that genotype in the individual).
Students can better understand the concept of phylogeny through incorporating evolutionary thinking into all aspects of biology. A recent study conducted by Grunspan and colleagues, for instance demonstrated that teaching about the evidence that supports evolution increased students' understanding of evolution in a college biology class.

Evolution in Action
Traditionally, scientists have studied evolution by studying fossils, comparing species, and okoopt.ru observing living organisms. Evolution isn't a flims moment; it is a process that continues today. Bacteria evolve and resist antibiotics, viruses reinvent themselves and elude new medications and animals change their behavior to the changing environment. The changes that result are often apparent.
It wasn't until late 1980s that biologists realized that natural selection can be observed in action as well. The key to this is that different traits result in a different rate of survival as well as reproduction, and may be passed down from one generation to another.
In the past, if an allele - the genetic sequence that determines colour was present in a population of organisms that interbred, it could become more common than any other allele. As time passes, that could mean that the number of black moths within a particular population could rise. The same is true for many other characteristics--including morphology and behavior--that vary among populations of organisms.
The ability to observe evolutionary change is easier when a particular species has a rapid turnover of its generation, as with bacteria. Since 1988, 에볼루션 Richard Lenski, a biologist, has studied twelve populations of E.coli that are descended from one strain. Samples from each population were taken frequently and more than 50,000 generations of E.coli have passed.
Lenski's research has demonstrated that mutations can alter the rate at which change occurs and the efficiency at which a population reproduces. It also proves that evolution is slow-moving, a fact that some people are unable to accept.
Another example of microevolution is that mosquito genes that are resistant to pesticides appear more frequently in populations where insecticides are employed. That's because the use of pesticides creates a pressure that favors individuals who have resistant genotypes.
The rapidity of evolution has led to a growing awareness of its significance, especially in a world which is largely shaped by human activities. This includes pollution, climate change, and habitat loss, which prevents many species from adapting. Understanding the evolution process can assist you in making better choices about the future of the planet and its inhabitants.
