Fossils
Knowledge did Darwin’s theory need in order to be tested, which he didn’t have at the time was fossils
- Even though Charles Darwin had access to a sizable collection of fossils that had been discovered up until the 1800s, a great deal more fossils have been discovered following his passing that are crucial pieces of evidence for the Theory of Evolution.
- Many of these "newer" fossils represent human predecessors and confirm Darwin's theory of human evolution by "descent through modification."
- When Darwin first proposed the theory that humans were primates and related to apes, the majority of his evidence was circumstantial; however, many fossils have subsequently been discovered to fill in the gaps of human evolution.
- Even though the theory of human evolution is still very debatable, more and more information keeps coming to light that supports and updates Darwin's initial theories.
- However, until all intermediate fossils of human evolution are discovered or until religion and people's religious beliefs vanish, this aspect of evolution is likely to remain debatable.
- Since things are unlikely to occur, there will always be doubts about how human evolution took place.

A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Another name for food web is consumer-resource system.

To calculate the frequency of the allele we use the Hardy-Weinberg equation. The Hardy-Weinberg equation is used to calculate the genetic variation of a population at equilibrium. If the alleles are A and a, p is the frequency of the allele A and q is the frequency of the allele a. Hardy-Weinberg equation for alleles A and a:
p² + 2pq + q² = 1
p² is the frequency of the homozygous genotype AA, 2pq is the frequency of the heterozygous genotype Aa and q² is the frequency of the homozygous genotype aa.
p²+2pq+q²=(p+q)²=1
p+q=1
