Question 7

Natural Selection

Answer 7

Put very simply, he proposed that organisms produce excess 
offspring which then compete for resources. The offspring with the 
best inherited adaptations survive to reproduce, and so populations 
gradually change to suit their environments.

If two sub-populations are exposed to different environments, they 
will gradually come to differ from each other. Given long enough, in 
a variable environment, ancestral populations will give rise to two (or 
more) quite different descendant populations.

Question 8

Cladograms

Answer 8

Ancestor- where tree beings.
Point where two lines meet- speciation event
line before speciation event: ancestral lineage
clade includes ancestor and ALL descendants
