EVOLUTION
aspects of evolution
microevolution - evolution in alleles, but no serious immediate visual change (gradualism)
-
-
outbreeding
promotes heterozygosity; increases genetic variation; desirable traits can be introduced into population; to much outbreeding can cause loss of distinct MAIN breed
Bassica family (mustard wild plant) - due to outbreeding created many other plants: kale, broccoli, cauliflower, cabbage,
-
reproductive isolation
-
-
adaption to different pollinators (floral features attract specific animals to receive/deposit pollen)
evidence?
-
-
-
some species are very similar, thus must have a common ancestor
-
principles of evolution
-
-
-
-
evolution is not necessarily predictable - can happen through mutations HOWEVER is predictable through analysing changing environment
