Answer 1

Inheritance of acquired characteristics

Question 2

Five components of darwinism

Answer 2

Natural selection, perpetual change, Gradualism, common descent, multiplication of species

Question 3

Natural selection

Answer 3

If the environment changes natural selection can select for ew traits which are favoured in the new environment.

Question 4

Homology

Answer 4

Similarity due to sharing common ancestor

Question 5

Evidences for evolution

Answer 5

Biogeography, fossil record, homology, direct observation

Question 6

Vestigial structure

Answer 6

Remnants of features that served a purpose In organism’s ancestor

Question 7

Can natural selection increase or decrease heritable traits that exist in a population?

Answer 7

Yes

Question 8

homologous structure

Answer 8

Are anatomical variations in structure present in common ancestor

Question 9

Evolutionary/phylogenies

Answer 9

Are hypothesis among the relationship between groups.

Question 10

Analogous traits

Answer 10

Arise when groups independently adapt to similar environmental pressures in similar ways.

Question 11

Misconceptions of evolution

Answer 11

I) evolution is not goal oriented and there is no end point

Question 12

Misconception of evolution 2

Answer 12

It is like tinkering, slight modification of existing traits

Question 13

Misconceptions of evolution 3

Answer 13

Traits musts already exist in a population to be selected for

Question 14

Inclusive fitness

Answer 14

Sum of individuals fitness plus close family members (genes individuals pass to their offsprings plus genes close family members pass to their offspring)

Question 15

Analogy

Answer 15

Similarity due to convergent evolution
