many of the organisms living today have not been identfied because they are residents of deep oceans
singled cells
Yes, if it is not then technically it's not a fossil.
No, spontaneous generation has been disproven by scientific experiments and observations. It is no longer considered a valid explanation for the appearance of life or living organisms. The modern understanding of biology is based on principles of biogenesis, which states that living organisms can only arise from other living organisms.
It is difficult to estimate the exact number of living organisms on Earth today due to the vast diversity of life forms and the constant discovery of new species. However, scientists estimate that there are anywhere from 8.7 million to 1 trillion species currently living on our planet.
The observation that all living organisms are composed of cells, the idea that cells are the basic units of structure and function in living organisms, and the concept that all cells come from pre-existing cells all support the cell theory as it is stated today.

Yes, Robert Burns has living descendants through his various children and their offspring. Some of his direct descendants have been identified and are living today.
Yes, if it is not then technically it's not a fossil.
Not really. The closest living relatives to allosaurus are birds.

If a single cell is living on its own it is called a single-celled organism. There are millions of single-celled organisms alive today.
The Métis indigenous people of Canada are recognized by the Canadian Constitution as an Aboriginal people. They live in Canada today and so have living relatives today. The Métis are descendants of specific First Nations and European ancestry who live in identified communities that have a unique culture.
The scientist who developed today's naming system of organisms is Carl Linnaeus. He introduced the binomial nomenclature system in the 18th century, which assigns each species a two-part Latin name consisting of the genus and species. This system is still used today to classify and identify living organisms systematically.

No, that isn't a statement made about evolution. The theory of evolution concerns how organisms have changed over periods of time. Everything has to have come from something! However, all living organisms alive today have evolved from predecessors, or have not really evolved much at all, e.g. Gingko bilboa and several species of sea animals.
