DNA molecules contain the assembly instructions for every living creature. Scientists compare DNA from ancient and present creatures to identify genetic similarities among species. The genetic similarities among species is the main evidence of evolution theory.
Belt transects are useful in ecological studies because they provide a systematic way to sample and quantify the distribution of species within an area. By laying out a defined path and measuring the abundance of species along this path, researchers can gather valuable data on species composition, density, and diversity. This method is particularly helpful in studying the spatial distribution of organisms and understanding patterns in natural communities.
No, the biological species concept can be applied to both extant and extinct organisms. It is a useful framework for defining species based on reproductive isolation and gene flow within populations, regardless of whether those populations currently exist or not.
Useful evidence is relevant, reliable, and verifiable. It should be sourced from credible and reputable sources, be clear and easily understandable, and support the argument or claim being made effectively.
Biotic potential measures the maximum reproductive capacity of a population under ideal conditions. It is useful for living things because it helps determine the population growth rate and potential for species to thrive in a given environment. Understanding biotic potential can provide insight into how species may respond to changes in their habitat or population dynamics.
Supernova 1987A was useful because it was the first opportunity for scientists to study a nearby supernova in great detail. It provided valuable insights into the late stages of stellar evolution and the physics of supernova explosions. The data collected from Supernova 1987A has been instrumental in advancing our understanding of the life cycle of massive stars and the formation of elements in the universe.
DNA is a useful piece of evidence in studying evolution because it carries genetic information that can show how species are related and how they have changed over time. By comparing DNA sequences, scientists can track evolutionary relationships and understand how organisms have evolved and adapted to their environments.
Vestigial structures are remnants of features that were functional in the ancestors of a given species but are no longer useful in the current species. This supports the idea of evolution as it suggests that species have evolved over time from ancestors with different anatomical features. The presence of vestigial structures provides evidence of common ancestry and the gradual changes that have occurred over time through the process of evolution.
Because they are evidence of evolution!
Anatomy is a useful tool in gaining evidence for evolution. The most useful thing is to examine homologous structures, ie anatomical similarities between different species. The best example of this is the pentadactyl limb. It is found in humans, dolphins and bats. This shows that at some point in the past there must have been a common ancestor from which these 3 diverse groups of animals evolved.
Vestigial structures are considered critical evidence of evolution because they are remnants of organs or structures that have lost their original function through the process of evolution. These structures provide insights into an organism's evolutionary history and support the idea that species have changed over time. The presence of vestigial structures suggests that organisms have inherited traits from their ancestors, even if those traits are no longer useful.
Vestigial structures are remnants of organs or traits that were functional in ancestral species but are reduced or non-functional in present-day organisms. These structures provide evidence of evolution because they suggest that organisms have evolved from ancestors with different adaptations, and over time, structures that are no longer useful have become reduced or lost. This supports the idea that organisms have changed over time to adapt to their environment through the process of evolution.
Evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains much about the fact of evolution. That is what make a theory, explanation. Facts are useful, but uninteresting. Theories explain facts by gathering many convergent pieces of evidence and putting it into a logical and consistent whole.
Knowing how the evidence works means you can then use it to support or fight the accusations made.
Evolutionary trees help us understand relationships between species, trace the path of evolution, and predict common ancestors. They provide valuable insights into biological diversity, help in conservation efforts, and assist in understanding the spread of diseases.
A vestigial is an organ that serves no useful function in an organism.
AnswerIt explains how we got to be the way we are, logically and accurately. Understanding where the appendix came from is useful for understanding how it functions in the body today. The same is true for lots of body parts including systems like the immune system. Hope this helps!It is also important for doctors because of drug resistant bacterias and viruses which is a direct result of evolution through mutations and natural selection.
We don't use the word "true" to describe scientific theories. They either fit the facts or they do not. Darwin's theory of evolution fits most of the observed facts, and does so beautifully. A theory is useful if it makes successful predictions. Darwin's theory has absolutely zero to do with belief in God. The Catholic Church does not hate God, yet endorses the view that evolution has occurred in much the way Charles Darwin described. Is there a scientific theory that better explains the evidence from paleontology, geology, anatomy, and molecular biology? No. Therefore, we provisionally accept the theory of evolution as an accurate depiction of the origin of species. Again, this has nothing to do with whether or not God exists and/or loves you. Evolution is wrong. God is true.
