If the isthmus formed gradually rather than suddenly, the morphological species, biological species, and phylogenetic species concepts.
<h3>
What is Isthmus genetical species?</h3>
The formation of the Isthmus of Panama, a slender land bridge that connects North and South America, caused the Pacific and Caribbean populations of marine organisms to split off about 3 million years ago. On both sides of the isthmus, different species of snapping shrimp have been studied. There appeared to be seven pairs of species, with one species of each pair being found in the Pacific and the other in the Caribbean, according to the morphological species concept.
The various species pairs inhabit slightly different ocean depths. These species pairs, which are divided by the isthmus, were indeed the closest relatives of one another, according to the researchers' estimates of phylogenies based on mitochondrial DNA sequences.

Answer:
I don't know what type of diversity, but I know genetic diversity
Explanation:
genetic diversity is controlled by 4 processes. mutation, drift, migration and selection. each of them have a analogue at the level of species. speciation creates new species much as mutation creates new alleles
The vascular bundle in the shape of a single central cylinder in a root is called the Stele.
- Vascular bundles provide the following purposes: 1. Xylem: It is essential for delivering water-related elements to various areas of the plant. 2. Phloem: This tissue is in charge of delivering nutrients and food to the plant. 3. Cambium: By producing new xylem and phloem, it contributes to secondary growth in plants.
- A group of fundamental tissues found in the stem of a plant that includes cambium, xylem, and phloem. The procambium of the developing stem is where the vascular bundles grow. In the monocotyledons, vascular bundles are scattered throughout the stem in intricate configurations.
- The major vascular system of the plant axis and its accompanying ground tissues make up the plant stele.

An example of an integumentary system is the skin, hair, nails, glands, and associated nerves and muscles.
<h3>What exactly is indeed the integumentary system, and also what functions does it serve?</h3>
The integumentary system is one's body's outer layer.. It consists of your skin, nails, hair, as well as the glands and nerves beneath your skin. Your integumentary system protects your skin from bacteria, infection, injury, and sunlight by acting as a physical barrier.
<h3>What are the skin layers?</h3>
Skin is the largest organ in the body, spanning the full external surface. It is composed of three layers: the epidermis, dermis, and hypodermis, all of which differ significantly in anatomy and function.
