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.

If the evidence that species change gradually over time is found in?
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.
What did Darwin gain from observing island organisms?
Darwin gained crucial insights into the principles of natural selection and evolution by observing island organisms. He noted how species adapted uniquely to their environments, leading to variations that were often specific to particular islands. This evidence supported his theory that species evolve over time through the process of adaptation to their surroundings. These observations were pivotal in shaping his ideas, which he later articulated in "On the Origin of Species."
How is the theory of evolution supported by evidence from the fossil recordc omparative anatomy comparative embryology?
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.
Where did Charles Darwin make observations that helped him develop ideas about how species evolve?
Charles Darwin made crucial observations during his voyage on the HMS Beagle, particularly in the Galápagos Islands. There, he studied various species of finches and tortoises, noting their adaptations to different environments. These observations led him to develop his theory of natural selection, illustrating how species evolve over time in response to their surroundings.
How do fossils that form in different rock layers provide evidence of evolution?
Fossils' existence confirms that species are not fixed but can evolve into other species over time
How do fossils that formed in different rock layers provide evidence-of evolution?
Fossils' existence confirms that species are not fixed but can evolve into other species over time
What is the role of time in classifying organisms?
Over time species evolve into new species.

How is divergence an evidence of evolution?
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.
What evidence is there that species have not changed over time?
None.
Does an individual a population or a species evolve?
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.
The most direct evidence that evolution has occurred comes from what?
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.
The change in the inherited traits of species over long periods of time is called?
Evolve.
How do ring species provide evidence for evolution and the process of speciation?
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.
What is the process by which 2 species evolve in response to changes in each other over time?
coevolution
What is the evidence that species change gradually over time is found in?
The fossil record.
