Angiosperms are flowering plants, so I'd say flowers and the parts of flowers are a pretty common characteristic.
Since there’s nothing here other than what you’ve asked i’ll guess, an experiment that is more likely to be reliable will not use the first values it gets, will be done multiple times and the values will be close in number
Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.
It’s the study of people and the outside world
