How is the concept of phylogeny defined?
✔✔ Phylogeny refers to the documented evolutionary history and lineage of a
specific species or group of organisms.
What is the initial stage of the scientific method?
✔✔ The scientific process begins with observation, where a researcher
identifies and documents a phenomenon.
What is the term for analyzing complex systems by looking at their individual
parts?
✔✔ Reductionism is the approach of deconstructing intricate systems into
smaller, more manageable components to understand how they function.
What do we call physical traits in different species that are similar because they
were inherited from a common ancestor?
✔✔ These are known as homologies; they represent structural similarities
that reflect a shared evolutionary origin.
What are the fundamental units passed from parents to their children?
✔✔ Genes are the basic units of inheritance responsible for transmitting
biological information across generations.
,How do we describe similarities in body structures that evolved independently in
unrelated species?
✔✔ These are called analogous structures, which arise through convergent
evolution when different species adapt to similar environmental pressures.
What was the name of the massive landmass that joined all Earth's continents 250
million years ago?
✔✔ Pangea was the ancient supercontinent that existed before tectonic plates
drifted into their current positions.
RNA -ANSWER✔✔the first genetic material on Earth was most likely this
molecule
Linnaeaus -ANSWER✔✔the swedish botanist that devised our current,
hierarchical classification system
Scale naturae -ANSWER✔✔the pre-Darwinian worldview suggesting that
organisms were created by God and did not change over time
Hypothesis -ANSWER✔✔in science, this may be described as a tentative or
possible explanation
inheritance of the acquired traits -ANSWER✔✔Lamarck concluded that evolution
does occur the way we view it today, but rather it involves this process
where life most likely began -ANSWER✔✔in warm puddles
, amino acids -ANSWER✔✔the significance of the Miller-Urey experiment was the
abiotic production of this......
adaptation -ANSWER✔✔the inherited characteristics of organisms that enhance
their survival and reproduction in certain environments
natural selection -ANSWER✔✔Darwin concluded that this was the driver of
species change
convergent evolution -ANSWER✔✔organisms that share similar functionality
(like flying) but have different anatomy are the result of this process
individuals -ANSWER✔✔natural selection acts upon __________
evolution occurs at the level of ________ -ANSWER✔✔populations
allele -ANSWER✔✔an alternative version of a gene that may produce different
phenotypic effects
What are the two main characteristics of life? -ANSWER✔✔- the ability to
reproduce
- metabolic activity
5 major themes of biology -ANSWER✔✔1. Organization
2. Information
3. Energy & Matter
