How is homologous structures an example of evolution?
Though the forelimb of your cat or dog does not look much like your arms these are homologous structures that are almost identical bone for bone. This shows the common ancestry of all tetrapods and the closer common ancestry of you and your mammal pets.
Observing animal tracks is an example of what observation?
This is an example of indirect observation, where evidence of animal presence is inferred through the tracks left behind rather than directly observing the animals themselves.
What kind of observation is observing animal tracks to estimate polulation size?
This is an example of indirect observation - you are not seeing the animals directly but are viewing evidence of their existence.
A structure remaining in an animal but with no use at all is called?
A structure within an animal, but is not used and has no purpose, is known as a vestigial structure. For example, in humans, there is a small bone at the very end of the coccyx, which is purposeless. It is known as the "vestigial tail."
How does paleontology provide evidence of evolution?
AnswerThe fossil record is the primary source of evidence of past life forms.The fossil record is also an important source of evidence of evolution. However, Charles Darwin was able to develop his Theory of Evolution by Natural Selection largely without reference to fossil evidence. He saw evidence for evolution in present life forms. Another source of evidence for evolution is to be found in DNA.
The structure of the forelimb of a bird is similar in structure to that of the forelimb of a mammal suggesting that both descended from a common ancestor What is this similarity an example of?
Homologous structures - the forelimb structures are anatomically similar and were derived from a common ancestor; however, they have evolved completely different uses. This provides evidence for divergent evolution or adaptive radiation.
What forelimb of a bird and forelimb of a mammal descended from a common ancestor this similarity is an example of?
Homology.
The structure of the forelimb of a bird is similar in structure to that of the forelimb of a mammal suggesting that both descended from a common ancestor. What is this similarity an example of?
Homologous structures - the forelimb structures are anatomically similar and were derived from a common ancestor; however, they have evolved completely different uses. This provides evidence for divergent evolution or adaptive radiation.
The structure of the forearm of a bird is similar to that of the forearm of a mammal sugguesting that both desened from a common ancestor this similarity is an example of?
Homology.
Why is similarity in appearance and structure not a sound way of building accurate family trees?
Species may have similar appearances and structure but different genetic and evolutionary paths. For example, the wing of a fly and the wing of the bird.
What three criteria are used to determine whether something is homology?
The three criteria used to determine whether something is homology are similarity in structure, similarity in function, and evidence of shared ancestry. If two features meet these criteria, they are considered homologous.
What is Anatomical Similarity?
In biology, anatomical similarity refers to the fact that members of the same class of animals tend to have similar structures and organs, even though they may not look the same externally. For example, humans and horses share anatomical similarity, and nearly every structure in one can be found in the other -- although it might be difficult to identify: fingernails and hooves, for instance.
What is text evidence?
It is when you have any kind of text that has a structure, form, and purpose. For example, when you have an article about an interview with someone, then it can be formatted in question and answer. So the text evidence would be: Form: Question and Answer Structure: Interview Purpose: To inform the reader There are many, many more, but that is just an example.
What biochemical evidence is there supporting evolution?
One key piece of biochemical evidence supporting evolution is the similarity of genetic material across different species. For example, DNA analysis shows a high degree of similarity in the genes of humans and other primates, supporting the idea of a common ancestor. Additionally, the presence of vestigial structures and genes in organisms further supports the idea of evolution, as these features are remnants from ancestral forms.
An example of Biochemical similarity between two different organisms?
One example of biochemical similarity between two different organisms is the presence of hemoglobin in humans and other mammals. Hemoglobin is a protein that binds oxygen in the blood and is essential for oxygen transport in the body. The structure and function of hemoglobin are highly conserved across different mammalian species, demonstrating a common evolutionary ancestry.
