What is a fossil?
Fossils are fossilised (petrified) remains of animals/plants. A fossil though, is only a fossil, when it is from a different geological era.
How does that relate to evolution?
Evolution and fossils are very related. When we scan the DNA of different fossils, we find that the DNA can be similar to living species we have today, which helps us trace back their origins.
Tracing back a species origins is not something we do just to see how that species changed along time. When we manage to make an evolutionary chart of a species, we know how they changed, what they changed, and maybe not more, but very importantly, when the previous species were extinguished. If we know when they were extinguished, we can find out what caused that extinction:
- A lack of adaptation.
- Lack of resources.
- Temperature changes.
- Increase of predators.
- Deadly migrations.
- Other natural disasters.
So, in other words, by studying one species, we can study our own planet.

Answer:
Sounds closest to: Kwashiorkor
Explanation:
Kwashiorkor is a disease brought on by severe protein malnourishment. In Kwashiorkor, extended breastfeeding and late, insufficient weaning lead to low calorie intakes but significantly superior biological value. As a result, a kid with kwashiorkor will likely experience compromised organ function and development. Sudden outbreaks of diseases like the measles, gastroenteritis, or pneumonia exacerbate the issue by increasing needs while maintaining low intakes. The kid may exhibit oedema of the face and lower limbs, failure to grow, anorexia, diarrhea, lethargy, dermatosis, flaky-looking skin, scant, soft, and thin hair, angular stomatitis, cheilosis, and anemia as a result of this scenario.
This is a bit similar to Marasmus.
But there is a difference.
But ⇒ <em>how does kwashiorkor and marasmus differ?</em>
<em />
Kwashiorkor is predominantly a protein shortage, despite adequate calorie intake. When a youngster is weaned off of protein-rich breast milk, it frequently happens. The patient will show signs of oedema, an enlarged abdomen, and other conditions.
Marasmus is a total energy shortage that causes a body weight that is at least 60% below normal. The victim will only be malnourished.
This finding indicates the damage of the mid-brain
This is evident due to the Decerebrate posturing, which is characterized by abnormal extension in response to painful stimuli, that indicates damage of the midbrain. On the other hand, damage to the diencephalon or cortex, abnormal flexion, occurs when a painful stimulus is applied. While medulla damage results in flaccidity.
Well, since im living my first one still.. Ill do whatever i want in the first one, and then live out the second one as a good Christian to the best of my ability
hope this helps
