Evidence to support evolution

1) DNA research

2) Resistant organisms (Poison warfarin used to be give to kill rats, a ceratin gene gives rats resitance to wafarin there are populations that are warfarin resistant)

Speciation

Speciation- Where evolution can lead to new species

MNEMOMIC  I AM Stronger Pretending Change is Near           

1) ISOLATION 2) ADAPTATION 3) MUTATION 4) SURVIVAL OF THE FITTEST 5) PASSING ON GENES 6) GRADUAL CHANGE 7) NEW SPECIES

Genes

Chromosones are found in the nucleus of a human cell

Humans have 23 pairs of chromosones in each cell nucleus

Chromosones carry genes which control development in characteristics

Allele- different version of th same genes
