The earliest scientists put living things in two main category, and the second category was subdivided into two further classes, a second of which, broken into three levels. The two category; Thing that can kill us.- Things that we can kill. This second has two classes; non edible, and edible, which has three levels; yummy,- not too bad,- taste like sh..t, but better then nothing.

What did early scientists classify sponges as?
Early scientists classified sponges as plants because of their stationary nature and lack of obvious sensory organs. It was not until the 18th century that sponges were recognized as animals due to their ability to move, feed, and reproduce like other animals.
Why do scientists think the first living cells to appear on earth were probably anaerobic heterotraphs?
Scientists believe that the first living cells on Earth were likely anaerobic heterotrophs because early Earth lacked oxygen, and these organisms do not require oxygen for their metabolism. Anaerobic heterotrophs can obtain the carbon compounds they need for energy from organic molecules in their environment, making them well-suited for the conditions of early Earth.
What is the idea that living things from non living things?
The concept that living things can arise from non-living things is known as abiogenesis. This theory suggests that the conditions on early Earth allowed for the formation of simple organic molecules, which eventually led to the development of more complex biological systems. While the exact mechanisms of abiogenesis are still debated, it is thought to have played a crucial role in the origins of life on our planet.
What were probably the first living things?
The first living things on Earth were likely single-celled organisms such as prokaryotes, like bacteria and archaea. They appeared around 3.5 to 3.8 billion years ago in early Earth's oceans.
Early 19th-century scientists believed that living organisms differed from nonliving things as a result of possessing a life force that could create organic molecules from inorganic matter The term?
The term for this belief in a life force that could create organic molecules from inorganic matter is known as vitalism. Vitalism suggested that living organisms had a special property or essence that distinguished them from nonliving things and that this essence was responsible for the processes of life. This idea was later challenged and disproven with the development of modern biochemistry and understanding of chemical reactions in living organisms.
How did early scientists classify organisms?
They spilt them up in groups.
What did early scientists classify sponges as?
Early scientists classified sponges as plants because of their stationary nature and lack of obvious sensory organs. It was not until the 18th century that sponges were recognized as animals due to their ability to move, feed, and reproduce like other animals.
What can you learn about objects by classifying them?
you can trace the evolution of organisms backwards. this enables scientists to understand the species better as well as the living and climatic conditions on the early earth.
What event or development in early human history do you think is of particular signifacance?
The development of humans that walk upright and opposable thumbs. It helped scientists classify us as modern humans.
What did early scientist classify sponges?
a plant
What were early scientists not able to do to their theroies?
early scientists were not to test their theroies
Why do scientists think the first living cells to spear on earth were pobably anaerobic heterotrophs?
there was no oxygen in Earth's early atmosphere.
What have scientists from fossil records?
Fossils were of grear interest to early scientists because there: * appered to be of unusual, unknown organisms that were no longer living * are no fossils of most living species * buried very deep within rock more than 1km
Why might people long ago have begun trying to classify living things?
Early classification was probably begun to determine whether a plant or animal was harmful or beneficial to a person. Aristotle grouped organisms into two types, plant and animal, and animals were divided into three groups determined by how they moved.
Why did early scientists believe that life came from rain?
Early scientists were religious figures that followed pagan beliefs.
Why do people place value on nonliving things?
People place value on non-living things because it is in their nature. People are taught from an early age that even non-living things like property or possessions are precious.
