Why is evolution by natural selection called a theory?
Scientists use it to describe how organisms have changed over time.
Why do scientist sometimes change their ideas about classifying organisms?
They change their minds because they saw that the structure changed and it grew into a different size and it grew alot more details on them. Thats how scientists sometimes change their ideas about classifying organisms
Why have scientists changed their views about the model of life?
Because your mum made you and then they realised that was mistake and changed it
How has the work of linnaeus changed the way scientists work?
He completely changed the names from long Latin names to small Latin names where the first word in the genus and the second word is the species. So he changed the way scientists work as they had to use different names for animals, minerals and plants which made it easier for them as these words were more manageable and easier to say and work with! Hope that helped x
How has linnaeus system changed the way scientists work?
He completely changed the way in which living things are named
How have microscopes changed the world?
it helped scientists discover small organisms and make the periodic table

In addition to fossils how can scientists learn about an organisms ancestor?
Aside from fossils we can learn about organisms and how they have changed over the years by looking at the plants and animals we have today.

How has the heart developed and changed as organisms have become more complex?
There is no evidence that the heart has developed and changed as organisms have become more complex over time. Scientists do believe that the human heart is a product of evolution and has spent millions of years perfecting itself in order to keep humans alive.
What are three things scientists can tell from a fossil?
1. Fossils can help date rock horizons and can help identify similar environments when the same fossil is found in different locations; 2. Fossils helped identify how the different land masses moved/plate tectonics worked because similar fossils on different continents sometimes showed how the different land masses were once connected (e.g. Africa and South America); 3. Fossils can show how different species evolved over time.
What are 3 choices organisms have when their habitats are changed?
They can move, develop different adaptions, or change their life style.
Why has the classification system changed over the year?
The classification system has changed over the years because a newly discovered organism may be very much like two groups of organisms biologists may disagree on which group to put the organism into.
What might change a scientists mind about how to classify things?
They change their minds because they saw that the structure changed and it grew into a different size and it grew a lot more details on them.They might find out that there are more divisions or kingdoms (living organisms) which might change their minds.
How are genetically modified organisms different from non genetically modified organisms?
Genetically modified organisms (GMO) are different from non-genetically modified organisms in that GMO have had their genes manipulated and intentionally changed by human action in a laboratory. With GMO we can introduce any particular character by providing gene sequence responsible for that character

How can DNA be changed by scientists?
mutation
