Speciation Flashcards
Which condition is most likely to favour fossilisation?
Low oxygen levels and cold
Animals may be preserved in peat boys because:
The conditions need for decay are missing
The most likely reason that early life forms left few traces behind is?
Early forms of life was softbodied so did not fossilise well
Why do we have a good evolutionary record of the horse?
The fossil record of its ancestors is complete
What is likely to happen to an individual Poorly suited to its environment?
It will die
What is not likely to cause a species becoming extinct?
A new food source
New species can arise because of insolation. this means that?
When 2 populations become separated. example geographically
What sort of variation is inherited?
Genetic
When populations become so different that successful interbreeding is no longer possible,we call it?
