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.
What else can I help you with?
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 is an answer to an evidence based question called?
The answer to an evidence based question is called 'proof'.
What scientist did not have experimental evidence to support his theory of the atom?
John Dalton did not have experimental evidence to support his theory of the atom when he proposed it in the early 19th century. His atomic theory was based on observational patterns rather than direct experimental data.
A scientist is logical and systematic?
Yes, scientists use logic and systematic methods to conduct experiments, collect data, analyze results, and draw conclusions based on evidence. They follow specific procedures to ensure their research is rigorous and reliable.
What is the purpose of evidence based practice?
The purpose of evidence based practice that all decisions should be based on research study and physical evidence. It is used in medicine, dentistry and education for example.
What have scientist learn about the elephant shrew based on the 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 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 .
Why have scientists learned about the elephant shrew based on DNA evidence?
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.

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 have scientists learned about the elephant shrew based on DNA?
Most elephant shrew species were first described in the 1800s by scientists who classified them as shrewsbecause of obvious physical similaritie .
How could a scientist determine if a behavior is an instinct or is learned?
A scientist can determine if a behavior is instinctual by observing if it is present in all individuals of a species, without the need for prior experience. To determine if a behavior is learned, the scientist can observe if the behavior changes over time based on experience or environmental factors. Controlled experiments and behavioral studies can also help differentiate between instinctual and learned behaviors.
Why do scientist analyze their data?
Analyzing data helps scientists explain their observations and their explanations are based on the evidence they collected.
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.
What A scientist makes the argument that she has found DNA evidence that shows that evolution does not exist. What would her evidence have to show for her to be correct?
For a scientist to argue that evolution does not exist based on DNA evidence, her findings would need to demonstrate that genetic mutations do not occur, that species do not share common ancestry, and that there is no evidence of natural selection influencing genetic variation over time. This would contradict the vast body of scientific evidence supporting the theory of evolution.
What made alchemy unscientific in its practice?
It was not based on evidence and experiment. - Alex Learning
Why is religion anathema to Richard Dawkins?
As a scientist, Richard Dawkins is strongly of the opinion that ones beliefs should be based on evidence of what is true, and that to believe something without evidence is foolhardy and dangerous. He sees religion as the epitome of belief without evidence, and as such feels a duty to denounce it.
Why did the scientist put an umbrella in his ear?
It's likely this is a joke or a play on words, as there is no logical reason for a scientist to put an umbrella in his ear. It's important to remember that scientists typically engage in logical and rational behavior based on evidence and research.
