Similar selection pressures lead to similar features the evolve in related species (7)
Reproductive isolating mechanism that occurs before fertilization (10)
Speciation that occurs abruptly (13)
Small population rapidly diverges to occupy new niches in adaptive radiation (13)

ACROSS:
7. study of the development of organisms that shows common ancestry, such as limb buds on a snake (10 letters)
14. type of evolution that involves a symbiotic relationship involving two unrelated species that depend on one another (11 letters)
16. structure similar characteristics due to common ancestry, such as bones in the limbs of tetrapods (10 letters)
19. structures that no longer have a function but are reduced forms, such as human appendix (9 letters)
20. type of evolution when two distantly related species develop similar characteristics, often because they have similar niches (10 letters)
21. theory that evolution occurs at a slow and steady pace (10 words)
DOWN
2. the process by which isolated populations of the same populations develop different characteristics (10 letters)
3. goosebumps are an example of this type of adaption (13 letters)
5. process by which those characteristics that permit survival and reproduction are continued and eventually replace less advantageous characteristics. ( 16 letters)
6. population numbers become very low then rebound, resulting in a change in allelic frequency. ( 10 letters)
9. process of dispersal, adaption, and subsequent speciation (17 letters).
15. random and permanent change in the DNA of an organism (8 letters)

ACROSS:
use energy for homeostasis
living things in their environment
heterotrophs
sequential re-growth of species
eats both meat &plants
CO2 & carbohydraytes are in this cycle
ticks, fleas, lice, lampreys…
manufacture their own food
deceptive or warning camouflage
your narrow niche makes you this
density (?) factors reduce popn due to its size
cycle that includes ammonification & fixation
tapeworm, roundworm, hookworm…
where Earth + atmosphere = life support
consumed by predator after the hunt
in commensalisms, only 1 species does this
S-curve, or growth where births = deaths
community very resistant to change
DOWN:
ecosystems waste recycler
total organic material in an ecosystem
dependent on tolerable environmental conditions
birth ___; death ___; mortality ___
species lifestyle &habitat determine this
nonliving
species (?) suggests ecosystems health
popn size the area can support (2words)
type of exclusion that drives 1 species out
large ecosystem w/distinct characteristics
earths insulation
close interactions among species
stable end point community
density-independent (?) hurt popn regardless of size
decomposers break this down
