As we Darwin tell us about finches of Galapagos island these finches are basically evolve from a single ancestral spices but now they become new spices basically on the basis of shape and size of there beak. an other example is the presence of connective links in nature like archeopetrics . this fossil organism is a connective link between reptiles and birds . Evolution takes place when environment makes a stress on an spices and spices also evolve to minimise competition.
Evidence that species change gradually over time is found in the fossil record, which shows transitional forms between species, indicating gradual evolution. Additionally, genetic studies reveal variations and similarities among species that support common ancestry. Observations of natural selection and adaptation in contemporary populations further demonstrate how species evolve in response to environmental changes. Together, these lines of evidence provide a comprehensive understanding of evolutionary processes.
The fossil record.
The theory of evolution is supported by the fossil record, which reveals a chronological progression of species and transitional forms that illustrate gradual changes over time. Comparative anatomy shows similarities in the structures of different species, indicating common ancestry; for example, the forelimbs of mammals, birds, and reptiles have similar bone structures despite differing functions. Additionally, comparative embryology demonstrates that embryos of diverse species exhibit striking similarities in early development, further suggesting a shared evolutionary origin. Together, these lines of evidence reinforce the concept that species evolve and adapt over time through common descent.
The gradual process by which certain species replace other species in an ecosystem is called ecological succession. This occurs as plant and animal communities evolve and adapt to changing environmental conditions over time.
Charles Darwin observed a wide variety of plant and animal species during his travels, noting how they adapted to their environments over time. This observation led to his theory of evolution by natural selection, which revolutionized our understanding of how species evolve.
Fossils' existence confirms that species are not fixed but can evolve into other species over time

None.
Divergence, where organisms evolve different traits over time, is evidence of evolution because it shows that species can change and adapt to new environments. When two populations of the same species diverge and develop distinct traits, it is an indication that they have evolved separately and are on different evolutionary paths. This process highlights the ability of organisms to evolve and adapt to changing conditions, which is a fundamental concept in evolutionary theory.
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.
Evolve.
Bacteria because they reproduce every 20 minuites which is fast enough so scientist can see them evolve over time. or Viruses, they evolve, that's why we have to constantly change are vacines.
Ring species provide evidence for evolution and speciation by demonstrating how populations can gradually evolve and diverge from a common ancestor over time. In a ring species, neighboring populations can interbreed, but as they spread out and encounter different environments, they may become reproductively isolated and eventually form distinct species. This process illustrates how new species can arise through gradual changes and adaptation to different environments, supporting the theory of evolution.
