Question

Look at picture attached

A) What does the phylogeny suggest about the evolutionary process that led to the trait differences by habitat?

a. convergent evolution

b. adaptive radiation

c. phenotypic plasticity

B) Choose different functional forms from two of the habitats shown in the collage and describe how one or more differences in form may represent an adaptation to their different environment. Example: compare plant form for lobeliads in montane bog to cloud forest understory

**Different species of lobelia in Hawaii take the following forms in these habitats:**

- **(a)** Montane bog
- **(b)** Wet subalpine
- **(c)** Cliffs
- **(d)** Cloud forest (montane rainforest)
- **(e)** Cloud forest understory
- **(f)** Cloud forest gap
- **(g)** Forest edge

**Phylogeny Diagram Explanation:**

On the right is a phylogeny for the group, highlighting the Hawaiian lobeliads within the green shaded rectangle and showing their close relatives elsewhere. The colors of the branches correspond to different habitats:

- Wet alpine/subalpine (purple)
- Cliffs/rocky outcrops (bright pink)
- Rain- or cloud-forest interiors (light green)
- Rain- or cloud-forest gaps or canopies (dark green)
- Mesic forest (brown)
- Coastal scrub (yellow)
- Desert (blue)
- Temperate meadow (light blue)
- Equivocal (gray)

This branching diagram showcases the evolutionary relationships of various lobelia species and their adaptations to distinct environmental conditions.

Expert Solution
Step 1: Evolutionary process

If the Lobelia plant species in different parts of Hawaii exhibit significantly varied traits that are passed down through generations and are well-suited to specific habitats, it strongly indicates a case of adaptive radiation.
