Cb4a- evidence for human evolution Flashcards
what is meant by the term evolution?
The slow and continuous change of organisms from one generation to another.
What are the binomial species names?
HINT: Dear King Philip came over for Good soup
Domain Kingdom Phylum Class Order Family Genus Species
How does antibiotic resistance provide evidence for evolution?
The reason why antibiotic resistance provides evidence for evolution is that it makes the bacteria better adapted to the environment in which antibiotics are present. As a result antibiotic resistance becomes more common in the population over time. The emergence of other resistent organisms also provides evidence for evolution
How does bacteria create antibiotic resistance bacteria?
Bacteria sometimes develops random mutations in their DNA which create new alleles which can change the bacteria’s characteristics.one characteristic this can change is to give the bacteria the ability to resist antibiotics. This leads to a the allele for antibiotic resistance to be passed on to lots of its offspring which makes it common over time.
What are fossils?
A fossil is any preserved remains,impressions or trace of a once living organism.
How do tools provide evidence for evolution?
Tools provide evidence for evolution because stone tools are harder to disdruct than bones and stone artifacts. Stone tools provide us with information and evidence about the technology and the mental skills and ideas that early humans had.
How are stone tools dated from their environment?
Tools have been dated from their environment as it is dated by the age of the sediment layers are found in.
How have stone tools created by human-like species developed over time?
Uj
How did different organisms use tools in the past?
To gain water/food To groom For defence To recreate To consruct
What fossil evidence is their for different species
G
What is the genus and species of homo-sapens?
Homo is the genus
Sapens is the species
What are some issues with fossils?
Few organisms form fossils
The right conditions are needed to form fossils
Fossils can be destroyed due to geological activity
What is geological activity?
Geological activity is to do with weather/environmental conditions which damage or break the fossils.
Examples of geological activity are earthquakes and volcanos
