Question

guided notes worksheet: taxonomy & evolution (based on crash course biology #19 & #20)
taxonomy is the science of naming, describing, and classifying organisms into groups based on shared characteristics. carl linnaeus developed the modern system of classification, which uses a hierarchy of categories like kingdom, phylum, class, order, family, genus, and species. this system helps scientists communicate clearly about the diversity of life.
evolution is the process by which species change over time through mechanisms like natural selection, genetic drift, and mutations. charles darwins theory of evolution explains how species adapt to their environment and how new species arise. evidence for evolution includes the fossil record, comparative anatomy, and molecular biology.
fill in the blank: fill in the blank with the correct words.

1. the science of naming and classifying organisms is called _taxonomy_.
2. the system of classification that uses a hierarchy from kingdom to species was developed by _carl linnaeus_.
3. evolution happens over _natural selection_ periods of time and results in changes in populations.
4. structures in different species that are similar because of common ancestry are called _ structures.
5. the process by which organisms better adapted to their environment survive and reproduce is known as _.

word bank:
natural selection

homologous
carl linnaeus
long

Explanation:

1. Taxonomy is defined as the science of naming and classifying organisms in the provided text.
2. Carl Linnaeus developed the hierarchical classification system from kingdom to species.
3. Evolution occurs over long periods of time and natural selection is a mechanism of evolution, not the time - frame, so the correct answer is 'long'.
4. Structures in different species that are similar due to common ancestry are called homologous structures.
5. The process by which organisms better adapted to their environment survive and reproduce is natural selection.

Answer:

1. taxonomy
2. Carl Linnaeus
3. long
4. homologous
5. natural selection
