they know because they can look at different changes in the object of study/story/subject in which they are studying and calculate what the changes are and how long these changes have taken place for/over what perid of time/ for how long/ when it changed and then find out what has been happening over that time period/ frame.
What else can I help you with?
How do scientists know that living things have changed over time?
Scientists use various lines of evidence, such as the fossil record, comparative anatomy, embryology, and genetics, to show that living things have changed over time. By studying these pieces of evidence, scientists can construct evolutionary relationships and track changes in species over generations. This accumulation of evidence supports the theory of evolution.
Can scientists learn new things over time?
Yes
How our understanding of DNA and inherited has changed over time?
it was developed by many scientists over many decades. *apex*
How do scientists know that organisms have changed over time?
Scientists use evidence from the fossil record, comparative anatomy, DNA analysis, and observations of natural selection to understand how organisms have changed over time. By studying these pieces of evidence, scientists can track the gradual changes in species over generations, providing strong support for the theory of evolution.
How has our understanding of DNA and inherited traits changed over time?
it was developed by many scientists over many decades. *apex*
Scientists know how groups of animals changed over time by studying information contain in the?
Fossil Succession
Has the hubble telescope changed over time?
Yes it has. there is high tech things added to it.
What are two things that scientists learn from the fossils record?
The fossil record provides evidence about the history of life and past environment on earth. The fossil record also shows that different groups of organism have changed over time.
How has anemometers changed over time?
how the anemometer changed over time
How have the laws of physics changed of time?
The laws of physics have not changed over time. Our understanding of them has changed over time.
How can we use the word evolution in a sentence?
Scientists study the process of evolution to understand how species have changed and adapted over time in response to their environment.
True or false Lanmark was among the first scientists to recognize that living things have change over time?
True
