Passage 1
When I tell people what I do for a
living, wisecracking party guests will ask
me, "So, as an expert, what came first:
the chicken or the egg?" But in my line of
work, such a question is not only stupid
because it's unanswerable; it is stupid
because it does not matter.
I am an evolutionary biologist. My job
is to research and determine how evolution works. Evolution is the
process by which different kinds of living things developed and
diversified from earlier forms during Earth's history. The theory was
originally posited in Ancient Greece but later articulated more famously
by Charles Darwin in the nineteenth century. My particular field of study
only emerged in the 1930s and 1940s.
Though my evolutionary biologist colleagues study different aspects
of evolution, my specific focus is on genetics. I don't really care about
what species emerged and when; I only care about how the
transformation occurred. And the transformations in which I am most
interested are gene transformations. Genes are carriers of certain

to introduce his or her main topic.

Answer 1

The first sentence of Passage 12 introduces the main topic and uses an anecdote to engage the reader, setting up the discussion of the evolutionary biology work. Evolution is central in biology, guiding research and understanding of life's diversity and origins.

Step-by-step explanation:

The first sentence of Passage 12 serves to introduce the author's main topic by setting up a scenario in which a common jest leads into a discussion about their career in evolutionary biology. More specifically, it provides an anecdote that the author uses to draw the reader in before pivoting to talk about their work on genetic transformations and evolutionary theory. This introduction underscores the importance of evolution as the unifying theory in biology and sets the stage for the exploration of how this principle helps us comprehend a multitude of biological concepts and applications.

The theory of evolution by natural selection explains why and how organisms have changed over time, leading to the vast diversity of forms we see today. It also prompts further scientific inquiry in many sub-fields within biology, probing questions about the mechanisms of genetic transfer, the emergence of new species like the photosynthesis-performing sea slug, and the fundamental understanding of how life began and evolved.

Evolutionary theory in biology is grounded in the perspectives of historical evolutionists, and it is continuously reinforced by contemporary studies and observations, underscoring its role as a continuously relevant and guiding force in life science research today.
