Genetic Variation
For Example
Studied
Can Create
Genetically Distinct
Populations
Causes
Physical

Homologous
Traits
Lamarckism
Common
Ancestor
Change in Traits
Causes
Basically traits no longer useful get
eliminated
Established
Such as
Good traits
get passed on
Causes
Compared with
Is a
AKA Selective Breeding
Human Process
Results in
Crossbreeds and
Hybrids
Ex. Labradoodle
Means
Micro-evolution
This is by chance
Migration
Basically

For example
For example
Neanderthal
0.12% DNA

from modern
humans.

Embryos
For example
Human + Fish
Embryos
Both have
gills but
humans
lose it
before we
are born.
Means
Animals Share Ancient Genes
Genetics
Common Genes
We have 96% of genes common with chimpanzees
Genetic Lines Diverged
How common the genes are determine when.

Results In
Marine Environment
Selects Predators with similar body shapes.
Sharks + Killer Whale
They look the same but inside they are not.
