What are intermediate species? in an easy way to understand. And some examples?

An intermediate is a species which appears in the mechanism of a reaction, but not in the overall balanced equation. Examples: Amphibian/land vertebrate (Pederpes)- Intermediate form between primary aquatic Upper Devonian amphibians and early tetrapods. Lizard/snake (Pachyrhachis)—Intermediate form of snakes and an extinct lizard-like reptile. It was a primitive snake with limbs.

Explanation:

These are certain species that create “connecting links” or something like that, between the fossil record of life which help to show the slow process of speciatin.

[speciatin- the formation of new and distinct species in the course of evolution.]
