The mass extinctions that occurred 250 million years ago and 65 million years ago may have been due to gradual process or Catastrophic events.
Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.
<h3>
What are skeletal traits?</h3>
- The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
- Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
- Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
- We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).

The categorization of the characteristics based on whether they are describing chloroplasts or mitochondria are as follows:
- <u>Mitochondria:</u> carry out cellular respiration.
- <u>Chloroplasts:</u> carry out photosynthesis.
- <u>Mitochondria:</u> found in plant and animal cells.
- <u>Chloroplasts:</u> produce carbohydrates used as source of food for most living things.
- <u>Mitochondria:</u> abundant in human muscle cells.
- <u>Chloroplasts:</u> not found in animal cells.
- <u>Chloroplasts:</u> contain chlorophyll.
<h3>What is a cell?</h3>
A cell can be defined as the fundamental functional, structural and smallest unit of life, which is found within the body of an organism.
Some examples of cell organelles that are found in the body of an organism include the following:
- Mitochondria.
- Nucleus.
- Endoplasmic reticulum (ER).
- Vesicles.
- Cytoplasm.
- Cell membrane.
- Chromosome.
- Golgi apparatus (bodies).
- Chloroplast
<h3>What is
mitochondria?</h3>
Mitochondria can be defined as one of the cell organelles that is found in the body of a living organism.
Also, mitochondria is known as the powerhouse because it is saddled with responsibility of providing all the energy required in the cell, especially by transforming energy forms through series of chemical reactions.
