Sexual Selection
Sexual Selection:
Some genotypes are better than others at attracting/finding/securing mates, and this leads to change over time
Species:
a group of populations of interbreeding individuals that are reproductivley isolated from other populations
Phylum Porifera
sponges
Two layers of the Integument System
Epidermis
Dermis
Basic functions of the Circulatory System
move oxygen
Move wastes out of cells and body
Intersexual interaction involves?
Female and males
What problems are there with the biological species complex
Asexual species
extinct species
Different species mating together
Most abundent species on earth by weight
Phylum Nematoda
3 functions of the Integument System
Barrier
Communication
Exchange
2
Hepatic portal system (Gut and Lungs)
Intrasexual Interaction involves
male and male interactions
Speciation:
How many years does it take?
forming of two species from one
millions of years
Most diverse group of species on earth
phylum arthropoda
Epidermis vs. Dermis
Several answers
Arteries vs. Veins
Arteries= thick walls, carry blood away from heart
Veins= thin, carry blood to heart
What is it that females are doing within Intersexual Interactions
choosing particular traits
