The Road to Discovery

show/hide words to know

  • Collaborate: to work with other people on a particular task or goal.
  • Community: a group of interacting species that live in the same area.
  • Ecosystem: a group of different plants and animals that live together and are dependent on the area in which they live.

Finding Answers and Making Discoveries

Bacteria root nodulesMost biologists don't just wake up one day and start making discoveries. They spend many months, even years, working on a particular research question.

Biologists often must work very hard on many small experiments. Each one is like a piece of a puzzle, providing more information about a larger question.

Each time a biologist performs an experiment, they come one step closer to finding the answer to their larger research question.

How Do Biologists Figure Out the Big Picture?

Let's look at an example. A biologist observes that a special beetle only eats certain plants and avoids others. To understand why this is happening, she or he may need to investigate the fungi that grow in the plants or the microbes in the soil.

All of the species in an area are affected by the other species they live near. All of these organisms can in turn be affected by non-living influences, like the amount of rain the soil gets. So, to see the big picture, a biologist may need to study multiple pieces of a single ecosystem.

Listen to more of the story behind one type of grass and its community:

With so many living things to study and places to study them, it is very difficult understand everything. This can make it difficult to answer research questions about a whole ecosystem. But rather than having one person try to tackle all these different angles, biologists will often work together to explore a big question. We call working together collaborating.

Biologists Share Information and Work Together

For example, researchers used to look at dinosaur bones and the physics of flight to try to figure out how bird flight evolved. However, when researcher Ken Dial added a new piece to the puzzle (looking at how baby birds use their wings), the overall picture of bird flight evolution became a bit clearer.

In this way, when different researchers each solve a part of the puzzle, everyone can get a better understanding of the bigger picture.

Sometimes understanding what you're observing can be difficult. To see the big picture behind a question, you may need to look at it from new angles or work with other researchers.
