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

∙ 12y agoWell, it helps them understand whether the 2 species descended from a common ancestor or not, and also an estimate of how long ago the ancestors actually separated in 2 different species.
Scientist investigate the genes and their order in DNAs to draw results concerning a possible common ancestor of the 2 species.

∙ 14y agoDNA can be used to match two species and determine if they are related or share a common ancestor. In addition, the existence of DNA itself is proof for evolution on a large scale - virtually all organisms share the same nucleic acid as the genetic code, leading scientists to the conclusion that all species shared a common ancestor at one time.

HOPE THIS HELPED :)

Hope that helped ! ;D

Why do scientists classify animals and plants?
So they can determine the taxonomy of the species. i.e. it's genetic heritage by evolutionary processes. Originally it was simply used to tell the difference, as time went on it became necessary to group them into their apparent relationships to relevant species. As the theory of evolution was developed so did the level of taxonomy.
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 are earthworms called lumbricus terrestris?
Simply because they look like worms. Even the first person to discover one noticed that. They even taste like worms and is not a part of my cusine.
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.
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 determines whether two species are in the same genus?
By comparing the DNA sequences of two species we can tell whether they are same species or not.
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.
What are the similar body structures in different species tell scientists?
Back down the line, the species came from a common ancestor.
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.
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.
What do volcanoes tell scientists about the crust or mars?
They tell scientists when the wolrd will in
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.
What are two things a species name may do?
A species name may provide information on the scientific classification and relationship of an organism within the taxonomic hierarchy. It can also help in the identification and communication of a particular species, allowing scientists to have a standardized way of referring to and studying organisms.
