Bacteria
Anatomical structures are:Firstly, they are easy to observe in organisms and fossils.Secondly, fossils are the only evidence we are ever likely to have of extinct species
they need to know if the animal is a mammal or not, if the animal has a backbone or not, there are a lot of things one needs to know to identify an animal, i suggest getting an identification book on the animal(s) you are looking at.
Scientists use microscopes to observe and study tiny structures at a magnified level. Telescopes, on the other hand, are used to observe distant celestial objects in space.
It is advisable to adopt field research when you need to collect firsthand data in a natural setting, observe behaviors or phenomena directly, and gain a deeper understanding of a particular context. Field research is particularly useful for studying complex social interactions, cultural practices, and environmental dynamics.
The concept of a common ancestor in evolution suggests that all life on Earth shares a common origin, providing a framework to explain the diversity of species through gradual changes over time. It supports the theory of evolution by showcasing the interrelatedness of all organisms and the branching patterns of descent that have led to the vast array of species we observe today. By tracing back to a common ancestor, scientists can understand the evolutionary relationships among different species and how they have diverged and adapted over time.
Bacteria
To gain an understanding of how populations change over time, scientists often observe organisms with short generation times, such as fruit flies, bacteria, or certain plants. These organisms allow for quicker observation of changes in populations and genetic traits over multiple generations. By studying these organisms, scientists can infer how natural selection and other evolutionary forces shape populations over time.

The first scientist to observe living cells was Anton van Leeuwenhoek, a Dutch scientist, in the 17th century. He used a simple microscope that he designed and made himself to observe single-celled organisms in pond water, blood cells, and other living specimens. His discoveries laid the foundation for the field of microbiology.
Scientists observe a wide range of phenomena depending on their field of study, but common things they may observe include changes in temperature, patterns in data, behavior of organisms, chemical reactions, and the effects of certain stimuli on their subjects. The goal of these observations is to gather data and draw conclusions that help further our understanding of the natural world.
The first scientist to observe living organisms with a microscope was Antonie van Leeuwenhoek in the 17th century. He is known as the "Father of Microbiology" for his groundbreaking discoveries using primitive microscopes of his own design.
Anton Van Leeuwenhoek was first scientist who studied pond water and observed , discovered and described many organisms in 1773 .
A biologist or ecologist would typically observe organisms in the field or in a lab setting to study their behaviors, interactions, and characteristics. This helps to understand the organism's role in their ecosystem and how they are adapted to their environment.
The invention of the microscope allowed scientists to observe cells, microorganisms, and other small structures that were previously invisible to the naked eye. This discovery revolutionized our understanding of the complexity and diversity of living organisms, leading to advancements in fields such as biology and medicine. By magnifying these tiny structures, scientists were able to study the intricate details of living things and uncover new insights into their functions and behaviors.
