What are fossils? What do they tell us about the process of evolution?<br>​
vredina [299]

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.

Hope it helped,

Imagine that head shape is controlled by a maternal effect gene. The dominant h allele produces a oval-shaped head, while the re
Ostrovityanka [42]
The woman’s genotype is Hh because her father has the genotype hh. If the woman has children with a person who’s genotype is HH, you see 100% oval heads, you’d have genotype HH and Hh. If the woman has children with a person who is Hh, you expect 75% oval heads and 25% square heads with the genotypes HH, Hh, and hh. If she has children with some who is hh, you’d expect 50% oval, 50%square with genotype Hh and hh. To solve, use punnet squares!
