Question

Archaefructus, an early fossil angiosperm, was herbaceous and probably aquatic. Other seed plant fossils were woody and terrestrial. What should scientists conclude? (A) The earliest angiosperms were herbaceous and aquatic. (B) The earliest angiosperms were woody and terrestrial. (C) Other data must be considered in order to make a valid conclusion. (D) We cannot know the real history of angiosperms.

Answer 1

The scientists should conclude that other data must be considered in order to make a valid conclusion.

What is Archaefructus?

Archaefructus is an extinct genus of herbaceous aquatic seed plants with three known species. Fossil material assigned to this genus originates from the Yixian Formation in northeastern China, originally dated as late Jurassic but now thought to be approximately 125 million years old, or early Cretaceous in age.

Even with its revised age, Archaefructus has been proposed to be one of the earliest known genera of flowering plants.

Because of its age, lack of sepals and petals, and the fact that its reproductive organs (carpels and stamens), are produced on an elongate stem rather than condensed into a flower as in modern angiosperms,

Archaefructaceae has been proposed as a new basal angiosperm family.

An alternative interpretation of the same fossil, however, interprets the elongate stem as an inflorescence rather than a flower, with staminate (male) flowers below and pistillate (female) flower above.
