The evolution of seed habit first started in Gymnosperms.

Here's a step-by-step explanation:

1. The first plants on earth were algae, which are aquatic and do not have seeds.

2. The next step in plant evolution was the development of mosses. Mosses are non-vascular plants that reproduce using spores, not seeds.

3. After mosses, the next step in plant evolution was the development of ferns and fern-like plants, including pteridophytes like Selaginella and Psilotum. These plants are vascular, meaning they have tissues for transporting water and nutrients, but they still reproduce using spores.

4. The next major step in plant evolution was the development of gymnosperms. Gymnosperms are vascular plants that reproduce using seeds. This was a major evolutionary advancement because seeds can survive harsh conditions and can be dispersed over long distances, increasing the plant's chances of survival and reproduction.

So, the evolution of seed habit first started in Gymnosperms.
