Recent investigations into urban ecosystems suggest that localized thermal zones—often called heat islands—serve as the principal evolutionary driver behind the rapid phenotypic adaptations seen in city-dwelling vegetation. Proponents of this temperature-centric hypothesis point to modifications in leaf morphology, root length, and transpiration rates as direct physiological responses to elevated city temperatures.

Conversely, botanist Elspeth Vance argues that thermal gradients are not the primary catalyst for these physical modifications in urban flora. Vance's research demonstrates that urban soil contamination alters microbial symbiotic communities in the rhizosphere. According to Vance, it is this shifting soil microbiome, rather than ambient temperature, that regulates the internal chemical pathways dictating plant stress tolerance and overall structural traits.
Based on the texts, is the following statement true or false?
Statement: Botanist Elspeth Vance (Text 2) would agree with the proponents of the temperature-centric hypothesis in Text 1 that localized temperature shifts are the primary cause of physical adaptations in urban plants.
