The Shanidar cave sits in the Zagros mountains of the Kurdish autonomous region of Iraq, in a border region between Iran and southeast Türkiye. Within the cave is one of the longest-debated collections of Neanderthal remains.
Double fertilization is a complex mechanism in flowering plants, wherein two sperm cells fuse with the embryo sac. To achieve this, pollens released from anthers must interact with the plant's stigma, hydrate, and germinate ...

Pollen is a fine to coarse powder containing the microgametophytes of seed plants, which produce the male gametes (sperm cells). Pollen grains have a hard coat that protects the sperm cells during the process of their movement from the stamens to the pistil of flowering plants or from the male cone to the female cone of coniferous plants. When pollen lands on a compatible pistil or female cone (i.e., when pollination has occurred), it germinates and produces a pollen tube that transfers the sperm to the ovule (or female gametophyte). Individual pollen grains are small enough to require magnification to see detail.
