A recent study conducted by the Massachusetts Institute of Technology(MIT) has discovered
that river erosion(侵蚀) can lead to increased biodiversity in areas with minimal tectonic(地壳构造
的) activity.The researchers focused their attention on the Tennessee River Basin and examined
how the erosion of various rock types by the river had led to the separation and diversification of a
type of fish called the greenfin darter.As time passed，these separate fish populations evolved into
distinct families with genetic differences.
Scientist Thomas Near observed that the greenfin darter was exclusively found in the southern
half of the Tennessee River Basin.The researchers analyzed the genes of each fish in Near’s data
set and constructed an evolutionary tree.This tree helped them comprehend the evolution and
differences of the greenfin darter species.They discovered that the fish within the same branch of
the river were more closely related to each other than to the fish in other branches.
This study provides evidence that river erosion significantly impacts biodiversity in regions
with low tectonic activity.It illustrates how changes in the landscape caused by river erosion can
lead to the division and diversification of species over time，even in peaceful environments.These
findings enhance our understanding of the mechanisms( 机 制 ) that drive biodiversity and
evolution，even in areas that are not typically associated with intense tectonic activity.
Subsequently，the team discovered a strong correlation between the habitats of the greenfin
darter and the type of rocks present.The southern half of the Tennessee River Basin consists of
hard，tightly packed rocks，resulting in turbulent(湍急的) waves in the rivers that flow through
it.This characteristic may be favored by the greenfin darter.As a result，the team assumed whether
the distribution of greenfin darter habitats had been influenced by the changing rock types，as the
rivers eroded the land over time.To test this assumption，the researchers developed a simulation
model.Remarkably，the results confirmed their assumption.
1．What is new about the MIT study?
A．It finds river erosion can enhance biodiversity.
B．It further proves the mechanisms of river erosion.
C．It proves the geographical features of biodiversity.
D．It classifies a type of fish called the greenfin darter.
2．What can we learn about the greenfin darter?
A．Their appearances vary between families.B．Their genetic constitutions have diversified.
C．They prefer the deep and slow-flowing river.
D．They go extinct in the changing landscape of rivers.
3．How did Near help the researchers reach their conclusion?
A．By creating an evolutionary tree of the fish.
B．By offering the fish’s genetic data.
C．By reasoning out the time the fish evolve and separate.
D．By analyzing the genetic similarity between different fish.
4．What is the best title for the text?
A．River Erosion Can Shape Fish Evolution
B．Genetic Change in the Greenfin Darter
C．Evolutionary Tree Analysis of the Greenfin Darter
D．The Impact of Climate Change on Fish Diversity
