By looking at different, small sections of DNA scientists can identify how many of them are shared exactly with another species and how far others diverge. The possibility of having the same genetic code due to convergent evolution, rather than it coming from a shared ancestor is so minute that scientists can say with a large degree of certainty how closely species are related

Why do scientists classify animals and plants?
Scientists classify animals and plants to organize and understand the vast diversity of life on Earth. This classification system helps to identify relationships between different organisms, study their characteristics, and make it easier to communicate and share information about species.
Why do biologists and scientists classify living organisms?
Actually there is two main reasons why biologists or scientists general classify things, and they are 1. It enables the organisation of organisms into the 8 kingdoms (kingdom, phylum, class, order, family, Genus and species), which lets the scientists or biologists, see the information about the organisms and the relationships between them. 2. It also makes it easier for scientists to communicate information about the organism and study them to understand their characteristics and behavior etc. This helps keep up with different types of animals. Animals that have a pouch are marsupials. Some have a pouch and 4 legs, some have 2. They will be in the same Genus for having a pouch but not in the same species. The same species would include all with a pouch with 2, and another species for pouches with 4 legs. That is one example out of millions.
How could you distinguish between a species in which there is a lot of variation and two separate species?
Sometimes it is very hard to distinguish between a species where there is a lot of variation between that of a variation that is actually two separate species. Many times scientist disagree on how to tell these two things apart.
Why is it important to classify organisms?
Classifying organisms helps scientists organize and understand the vast diversity of life on Earth. It allows us to identify relationships between species, predict characteristics of organisms based on their classification, and study evolutionary patterns. This system also aids in conservation efforts by highlighting species at risk and guiding management strategies.
How do forensic scientists use bones to identify unknown individuals?
The structure and sizes of bones can be used by forensic scientists to identify unknown individuals. Different ethnic groups have different bone structures and there is stark contrast between the bones of males and females. Forensic scientists can use a single bone - if that is all they are provided with - to calculate the height, gender, and ethnicity. I do not know how they can tell, since I have not studied in that area, but they can usually tell with first glance what gender it should be. Also, different people have had unique medical records. Records of fractures, or breaks, or simply bone stress can help if forensic scientists see a certain feature (i.e, a fracture line). The skull is probably the most important out of all the bones for identification. The skull can clearly show scientists what gender, age, ethnicity the person was. Even an untrained person can tell if they know what to look for. For example, males have a sharper brow and squarer jaw, while females have more rounded skulls. Teeth can help - especially if the scientist has access to dental records. The number and type of teeth in someone's mouth can tell you their approximate age and daily diet. There was probably a lot of peripheral information in here, but I hope this helped!
Scientists can tell whether organisms are closely related by comparing their?
Scientists can tell whether organisms are closely related by comparing their DNA. This will allow then to look at various traits and features so as to compare the relationship between organisms.
How do you tell if you have a fat neon tetra?
Simply by looking at it and comparing it with others of the same species.
2 Scientists can tell whether organisms are closely related by comparing their?
2.Scientists can tell whether organisms are closely related by comparing their ____.(1 point)DNA, I had this on my test too and I answered DNA and got it right.
What are the similar body structures in different species tell scientists?
Back down the line, the species came from a common ancestor.
What can body structures tell you about how species might be related?
Body structures can indicate shared ancestry among species. Similar anatomical structures suggest a common evolutionary origin, while differences in structures can provide insight into how species have adapted to different environments or ecological niches over time. Comparing body structures helps scientists determine the degree of relatedness between species and understand their evolutionary relationships.
What Scientists can tell that hominids walked upright by comparing fossilized leg bones to those of modern humans?
A paleoanthropoligist is the scientist who deals with fossilized bones.
How the fossils can give us information about their specie?
Fossils can provide information about a species through their morphology, which includes features like size, shape, and structure. By comparing fossils to known species and studying their environment, scientists can make inferences about the behavior, diet, habitat, and evolutionary history of the organism. Additionally, isotopic analysis or DNA extraction from fossils can offer insights into the genetics and diet of the species.
What can fossils tell us about the movement of the plates in the past?
Fossils can provide information on the distribution of ancient species across different continents, which helps in reconstructing past continental positions. By comparing the similarities and differences in fossil species found on separate continents, scientists can infer the movement and interaction of tectonic plates in the past. Fossils can also reveal how environmental changes associated with plate movements influenced the evolution and distribution of species over time.
Why are the frogs disappearing and what species?
I don't know but I can tell you that the water-holding frog isn't 1 of those species endangered. Scientists have researched and gone in to more detail about them but they are no threat to be endangered.
Most of what scientific know about extinct species is based on?
Most of what scientists know about extinct species is based on the study of bones and fossils. Scientists have studied many dinosaur bones to determine what they ate and how they lived. Fossils tell what the land was like at a given time in history.
How many animals are excinct?
It is hard to determine exactly how many animal species are extinct because some species become extinct before scientists even know they existed. As far as science can tell, there are over 900 extinct species.
How can scientists predict what the species looked like if its skin have decomposed?
There is no exact way to tell. But scientists can make a good guess. Calculating the overall size and muscle mass of the species will give them an approximate idea on how the skin would stretch over their bodies. As for color, there is only basing the ancestral color off of a more modern version of the species.
