Scientists have learned that the elephant shrew, despite its name, is more closely related to elephants and sea cows than to true shrews, based on DNA evidence. Genetic analysis has revealed distinct evolutionary lineages, placing elephant shrews in a clade called Afrotheria, which includes various mammals native to Africa. This insight has reshaped our understanding of mammalian evolution and biodiversity, highlighting the complex relationships between different species. Such findings underscore the importance of molecular data in clarifying phylogenetic relationships that traditional morphology alone could not resolve.

What have scientists learned about the elephant shrew based onDNA evidence?
Scientists have discovered that elephant shrews are more closely related to elephants and manatees than to other small mammals, despite their size and appearance. DNA evidence has revealed that they belong to a unique group called Afrotheria, which includes diverse species that share a common ancestor. This genetic analysis has reshaped our understanding of mammalian evolution and highlighted the complexity of relationships among species. Additionally, these findings have prompted further research into the evolutionary history of other African mammals.
Do scientists have proof that mermaids exist?
No, scientists have not found any evidence or proof that mermaids exist. The concept of mermaids is largely based on folklore and mythology, rather than scientific observation or documentation.
How many stomach does an elephant has?
An elephant has only one stomach, like most mammals. However, an elephant's stomach is divided into multiple compartments, including the rumen and hindgut, which help with digestion of the plant-based diet.
Who played the character John Merrick in the film The Elephant Man?
In 1980 actor John Hurt played the character of John Merrick in David Lynch's film, "The Elephant Man." The story is true and is based on the deformity of John Merrick.
What does the elephant represent in the blind men and the elephant?
In the story, the elephant represents how different perspectives can lead to incomplete understanding. Each blind man touches a different part of the elephant (tusk, trunk, ear, etc.) and describes it based on their limited experience, but none can fully comprehend the whole creature. This teaches the lesson that we should be open to others' perspectives to gain a more complete understanding of complex issues.
What have scientists learned about elephants shrew based on DNA evidence?
Most elephant shrew species were first described in the 1800s by scientists who classified them as shrewsbecause of obvious physical similaritie .

What have scientist learned about the elephant shrew based in DNA evidence?
Scientists have discovered that elephant shrews are more closely related to elephants and aardvarks than to other small mammals, despite their name suggesting otherwise. DNA evidence has revealed that these unique creatures belong to a distinct group called Afrotheria, which includes several African mammals. This surprising genetic relationship highlights the evolutionary history and biodiversity of African fauna, offering insights into how these animals adapted to their environments over millions of years.
Why is it important that scientists conclusions are based on evidence?
They rely on there conclusions based on observations.
What is the learned information from an investigation based on scientific evidence called?
The learned information from an investigation based on scientific evidence is called empirical knowledge or empirical evidence. This refers to knowledge that is gained through observation, experimentation, and validation in a systematic and objective manner.
What are four ways Greek scientists based their theories?
Like every other scientists, Greeks based their theories on observations, experiments, proofs, evidence and more.
Who said humans evolved from a primate?
Many scientists have said so based on the evidence they found.
Do scientists base their explanations of the natural world on evidence or belief why?
They have evidence, but if they cant prove something, even with the evidence, it becomes a theroy, or belief. So sometimes it is based on evidence and fact, sometimes on belief.
Scientists need to be skeptical so that they can?
Scientists need to be skeptical in order to question assumptions, critically evaluate evidence, and ensure the validity and reliability of their findings. By being skeptical, scientists can avoid bias, uncover errors, and make more accurate conclusions based on empirical evidence.
Why do scientist analyze their data?
Analyzing data helps scientists explain their observations and their explanations are based on the evidence they collected.
How did scientists determine that the Earth's mantle existed?
Scientists used detectors which determined the mantle existed. As well, scientists must hypothesize and theorize what cannot be readily seen, and make determinations based on the evidence that does exist.
