Evolution
CHRISTIAN BUENO
P.2
Charles Darwin
 “Grandfather of Evolution”
 Theory of Natural Selection
 “Origin of Species”
Jean-Baptiste Lamarck
 First person to attempt an explanation of Evolution
 First to put the idea of Evolution into a Scientific
Theory
 Father of “Lamarckism”
 Lamarckism is the idea that an organism can pass on
characteristics that it acquired during its lifetime to
its offspring
 Lamarck proposed the inheritance of acquired traits,
which was later proved to be wrong
Charles Lyell
 “Principals of Geology”
 Lyell argued that the formation of Earth's crust took
place through countless small changes occurring
over vast periods of time
Gregor Mendel
 Created the Theory of Inheritance and Heredity
 “Mendel’s Genetics”
Alfred Russel Wallace
 Contributed to the Theory of Natural Selection with
Charles Darwin
 Wallace effect, a hypothesis on how natural selection
could contribute to speciation by encouraging the
development of barriers against hybridization.
Homologous Structures and Vestigial Organs
 Homologous Structures – Similar Body parts of two
organisms that share a common ancestor
 Vestigial Organs – an organ that no longer has a
useful function in an organism (Tail in humans)
Development in Brain Size
 Humans have Protein Domain in the genome, and
more than 270 copies of it, more than any other
species
 Protein Domain at issue (Scientifically) is called
DUF1220
 The Closer a species is to a human, the more Protein
Domain they have, for example Chimps
Development of Language
 Humans are the only Species that has evolved with
an advanced system of communication between
individuals, while other species communicate
through calls, gestures of songs, we humans have
language
 First language appeared between 30,000 and
100,000 ago in Homo Sapiens
Coevolution is the
change of a biological
object triggered by the
change of a related
object
An Example :
Yucca moths and yucca
plants
Yucca flowers are a
certain shape so only
that tiny moth can
pollinate them. The
moths lay their eggs in
the yucca flowers and
the larvae (caterpillars)
live in the developing
ovary and eat yucca
seeds.
