- NEW SPECIES
- SPECIATION is the formation of a new species.
- 1 cause of speciation is the geographical separation of populations
- SPECIATION is the formation of a new species.
- populations of the same species
- become separated geographically e.g. they move to different islands; the environment between them changes so they can't cross it
- natural selection is the different areas favours different variations of characteristics
- characteristics of each population change due to natural selection
- characteristics may become so different that individuals from different populations could not interbreed successfully even if they were in the same area
- they are now different species
- characteristics may become so different that individuals from different populations could not interbreed successfully even if they were in the same area
- characteristics of each population change due to natural selection
- natural selection is the different areas favours different variations of characteristics
- each population has a wide range of alleles that controls their characteristcs
- become separated geographically e.g. they move to different islands; the environment between them changes so they can't cross it
