What did Albert Einstein most likely mean by this quote?

• A theory proves only one specific path of scientific knowledge, but other scientists break it up into broad paths of knowledge.

• Universally accepted scientific knowledge is easy to come by because it only requires one experiment

• Universally accepted scientific knowledge does not come easily because it surrounded by a large body of discussion and debate.

• A theory is only born when it is known that it will be impossible for the theory to ever be disproved.

What is an important part of being a scientist?

• seeking evidence to argue for or against knowledge that provides the best possible explanation of phenomena in the natural world

• seeking to be a part of a team of scientists that the world acknowledges as the best scientists

• seeking evidence that only argues against a current scientific theory

• seeking answers to only simple questions about the natural world

In 1861 paleontologists announced that they had found a fossil with feathers, which lived approximately 150 million years ago. When comparing this fossil to other small dinosaurs and modern-day birds, paleontologists learned that it had more in common with dinosaurs. They were small and had broad wings which likely gave them the ability to fly or glide. How can these fossils be used to support the theory of evolution?

• can demonstrate that animals from long ago are still alive today. 

• show how organisms today share characteristics with fossilized species.

• give evidence to support the idea that organisms inherit the best traits from their parents. 

• indicate that evolution is a theory because scientists do not completely understand the fossil record.
