Describe the anatomical evidences of evolution
Answers
Explanation:
With the technology available to scientists today, there are many ways to support the Theory of Evolution with evidence. DNA similarities between species, knowledge of developmental biology, and other evidence for microevolution are abundant, but scientists haven't always had the capabilities to examine these types of evidence. So how did they support evolutionary theory before these discoveries?
The main way scientists have supported the Theory of Evolution throughout history is by using anatomical similarities between organisms. Showing how body parts of one species resemble the body parts of another species, as well as accumulating adaptations until structures become more similar on unrelated species are some ways evolution is backed up by anatomical evidence. Of course, there is always finding traces of long-extinct organisms that can also give a good picture of how a species changed over time.Traces of life from the past are called fossils. How do fossils lend evidence in support of the Theory of Evolution? Bones, teeth, shells, imprints, or even entirely preserved organisms can paint a picture of what life was in time periods from long ago. Not only does it give us clues to organisms that are long extinct, but it also can show intermediate forms of species as they underwent speciation.
Scientists can use information from the fossils to place the intermediate forms in the right place. They may use relative dating and radiometric or absolute dating to find the age of the fossil. This can help fill in gaps in the knowledge of how a species changed from one time period to another throughout the Geologic Time Scale.
While some opponents of evolution say that the fossil record is actually evidence of no evolution because there are “missing links” in the fossil record, it does not mean evolution is untrue. Fossils are very hard to create and circumstances need to be just right in order for a dead or decaying organism to become a fossil. There most likely are also many undiscovered fossils that could fill in some of the gaps.
Answer:
Anatomical evidences are evidences of evolution.
Explanation:
1. Human hand, cat's forleg, flipper of whale and patagium of bat show diffrence in their features.
2. These organs also have different uses
3. However, the structure of bones and bony joints in organs of each of those animals show similarity.
4. This is an indication that all these animals originated from a common ancestor.
