The Berkeley Evolution Site
The Berkeley site offers resources that can assist students and teachers to understand and teach about evolution. The materials are organized in optional learning paths for example "What does T. rex look like?"
Charles Darwin's theory of natural selection explains how in time, creatures better able to adapt biologically to changing environments survive and those that do not become extinct. This process of evolution is what science is all about.
What is Evolution?
The term "evolution" can have many nonscientific meanings, such as "progress" or "descent with modification." Scientifically it refers to a changing the characteristics of organisms (or species) over time. In biological terms, this change is based on natural selection and genetic drift.
Evolution is a key tenet in the field of biology today. It is a concept that has been tested and proven by a myriad of scientific tests. Evolution doesn't deal with God's presence or spiritual beliefs, unlike many other theories of science, such as the Copernican or germ theory of disease.
Early evolutionists like Erasmus Darwin (Charles’s grandfather) and Jean-Baptiste Lamarck believed that certain physical traits were predetermined to change in a step-like fashion over time. This was known as the "Ladder of Nature", or scala Naturae. Charles Lyell used the term to describe this idea in his Principles of Geology, first published in 1833.
In the early 1800s, Darwin formulated his theory of evolution and published it in his book On the Origin of Species. It states that all species of organisms share the same ancestry, which can be traced through fossils and other evidence. This is the modern view of evolution, which is supported by numerous lines of scientific research, including molecular genetics.
Scientists don't know how organisms evolved but they are sure that natural selection and genetic drift is the primary reason for the development of life. People with advantages are more likely to live and reproduce. They transmit their genes on to the next generation. Over time, the gene pool gradually changes and develops into new species.
Some scientists also employ the term evolution to describe large-scale evolutionary changes like the creation of the new species from an ancestral species. Certain scientists, such as population geneticists, define evolution in a more broad sense by talking about the net change in allele frequency over generations. Both definitions are acceptable and accurate however some scientists believe that the allele-frequency definition omits important features of the evolutionary process.
Origins of Life
The development of life is a crucial step in the process of evolution. The emergence of life happens when living systems begin to develop at a microscopic level, such as within individual cells.
The origin of life is a topic in many disciplines that include biology, 에볼루션사이트 (Www.tianxiaputao.com) chemistry, and geology. The nature of life is a subject that is of immense interest to scientists because it challenges the theory of evolution. It is often called "the mystery of life" or "abiogenesis."
Traditionally, the belief that life can arise from nonliving things is known as spontaneous generation, or "spontaneous evolution." This was a popular view before Louis Pasteur's research showed that it was impossible for the emergence of life to be a result of a purely natural process.
Many scientists believe it is possible to transition from nonliving substances to living ones. The conditions needed to make life are not easy to replicate in a laboratory. Researchers who are interested in the origins and evolution of life are also keen to learn about the physical characteristics of the early Earth as well as other planets.
In addition, the development of life is dependent on the sequence of extremely complex chemical reactions that can't be predicted based on basic physical laws on their own. These include the reading of long information-rich molecules (DNA or RNA) into proteins that perform some function as well as the replication of these intricate molecules to create new DNA or RNA sequences. These chemical reactions are comparable to the chicken-and-egg problem: the emergence and development of DNA/RNA, the protein-based cell machinery, is essential for the beginning of life. Although without life, the chemistry that is required to create it is working.
Research in the area of abiogenesis requires collaboration between scientists from many different fields. This includes prebiotic chemists, astrobiologists, planetary scientists geophysicists and 에볼루션 코리아 슬롯게임 (https://www.play56.net/home.php?mod=space&uid=4160584) geologists.
Evolutionary Changes
The term "evolution" is commonly used to describe the accumulated changes in genetic characteristics of populations over time. These changes may result from adaptation to environmental pressures, as explained in the article on Darwinism (see the entry on Charles Darwin for 에볼루션 바카라 background) or natural selection.
The latter is a mechanism that increases the frequency of genes that offer an advantage in survival over others and causes gradual changes in the overall appearance of a particular population. These changes in evolutionary patterns are caused by mutations, reshuffling genes during sexual reproduction, and the flow of genes.
While mutation and reshuffling of genes are common in all living organisms and the process by which beneficial mutations are more frequent is called natural selection. As noted above, individuals with the beneficial trait have a higher reproduction rate than those who don't. Over the course of several generations, this difference in the number of offspring born could result in gradual changes in the number of beneficial traits in a population.
A good example of this is the growing the size of the beaks on different species of finches found on the Galapagos Islands, which have developed different beak shapes that allow them to easily access food in their new environment. These changes in form and shape can also aid in the creation of new species.
Most of the changes that take place are caused by one mutation, but occasionally several will happen at once. The majority of these changes could be harmful or neutral however, a few may have a positive effect on survival and reproduction with increasing frequency as time passes. This is the way of natural selection, and it can eventually result in the accumulating changes that eventually lead to the creation of a new species.
Many people mistakenly associate evolution with the concept of soft inheritance, which is the idea that traits inherited from parents can be changed by deliberate choice or misuse. This is a misinterpretation of the biological processes that lead to the process of evolution. It is more precise to say that evolution is a two-step independent process, that is influenced by the forces of natural selection as well as mutation.
Origins of Humans
Modern humans (Homo Sapiens) evolved from primates, a species of mammal species which includes chimpanzees and gorillas. The earliest human fossils show that our ancestors were bipeds, walkers on two legs. Genetic and biological similarities suggest that we are closely related to Chimpanzees. In fact our closest relatives are chimpanzees belonging to the Pan genus. This includes pygmy and bonobos. The last common ancestor between modern humans and chimpanzees was 8 to 6 million years old.
As time has passed humans have developed a variety of characteristics, including bipedalism as well as the use of fire. They also developed advanced tools. But it's only in the past 100,000 years or so that most of the essential characteristics that differentiate us from other species have developed. These include language, large brain, the capacity to build and use complex tools, as well as the ability to adapt to cultural differences.
Evolution happens when genetic changes allow individuals in a group to better adapt to their environment. Natural selection is the process that drives this adaptation. Certain traits are preferred over others. People with better adaptations are more likely to pass on their genes to the next generation. This is the process that evolves all species and forms the foundation of the theory of evolution.
Scientists refer to this as the "law of natural selection." The law states that species that share an ancestor will tend to develop similar characteristics as time passes. It is because these traits allow them to survive and reproduce within their environment.
Every organism has a DNA molecule that contains the information needed to control their growth. The DNA molecule is made up of base pairs arranged spirally around sugar molecules and phosphate molecules. The sequence of bases within each strand determines the phenotype - the distinctive appearance and behavior of an individual. Variations in a population can be caused by mutations and reshufflings of genetic material (known collectively as alleles).
Fossils of the first human species, Homo erectus and Homo neanderthalensis were discovered in Africa, Asia, and Europe. These fossils, despite differences in their appearance all support the hypothesis that modern humans' ancestors originated in Africa. The fossil and genetic evidence suggests that the first humans left Africa and migrated to Asia and Europe.
