In a few sentences, summarize Darwin’s theory of natural
selection.
Your Answer:
that too many offsprings were produced than an environment
could support would lead to offspings without desirable traits
would not survive versus the ones with the desireable traits in the
environment.
Question 8 / 8 pts 1
Natural selection posited that more offspring were
produced than an environment could actually support.
Survival in a crowded environment would lead to
struggle within a population, so the offspring that
inherited the most desirable traits for a certain
environment would ultimately survive. Over time,
variations would evolve in offspring that would make
them more adaptive, and ultimately over time, new
species could evolve.

Question 8 / 8 pts 2
Question 3 6 / 6 pts
Are preformation and epigenesis the same thing? Explain why or
why not.
Your Answer:
no they are not the same because epigenesis contradicts
preformation in which by epigenesis meaning a fertalized human
egg undergoes a specific developmental events that leads to
human formation while preformation means fertilized eggs
contained a small version of a completly developed adult
Preformation postulated that a fertilized egg contained
a miniaturized version of a tiny human. Epigenesis
directly contradicted that theory by stating that a
fertilized egg undergoes a series of developmental
events that eventually form a human
