Human evolution was proposed by Charles Darwin and is now widely accepted based on evidence. Fossils such as Lucy and the Taung Child provide evidence that humans evolved from primate ancestors in the forms of bipedal locomotion and increasingly large brains and smaller teeth. Comparative anatomy studies similarities between humans and primates like homologous structures that evolved from common ancestors. Genetic evidence also shows humans share 98.8% of DNA with chimpanzees and mutations provide variation for evolution. Overall, the evidence shows humans evolved from early hominins that shared ancestors with other primates.

7. Human evolution was proposed by Charles Darwin. It
states that humans came from modern sapiens.
Through evidence, his theory is accepted in science.
The following evidences are:
• FOSSILS EVIDENCES
• COMPERATIVE ANATOMY
•GENETIC EVIDENCES
•BEHAVIORAL EVIDENCE
INTRODUCTION

8. was a well-known English geologist, scientist,
and naturalist who made significant
contributions to evolutionary biology. His
theory that all living things share a common
ancestry is now widely recognized and
regarded as a fundamental idea in science.

9. HOW DID DARWIN ACTUALIZE HIS
THEORY?
Darwin's theories on natural
selection were shaped by his
journey to the Galapagos
Islands in 1835.
DISCOVERY EXPERIMENT
Experiment in pigeons gave
him evidence for evolution by
natural selection, allowing him
to study how far a species
could change

12. On November 24, 1974, fossils of one of
the oldest known human ancestors,
an Australopithecus afarensis specimen
nicknamed “Lucy,” were discovered in
Hadar, Ethiopia.
THE LUCY

13. The fossilized anatomy of the Taung Child
was the first time that scientists had
discovered proof of early human upright, two-
legged (bipedal) locomotion. The Taung
Child's foramen magnum, or the opening
through which the spinal cord communicates
with the brain, served as proof.

COMPERATIVE
ANATOMY

15. LOOK AT ME NOW LOOK AT YOU!

16. Comparative anatomy is the study of how
various animal species' bodies differ from one
another in order to comprehend the adaptive
changes that have occurred throughout their
evolution from similar ancestors...
WHAT IS COMPERATIVE
ANATOMY?

17. THE HOMOLOGOUS AND
ANALOGOUS
Are structures that are similar
in related organisms because
they were inherited from a
common ancestor..
HOMOLOGOUS ANALOGOUS
Analogous structures are
similar in unrelated organisms,
evolved to do the same job,
not inherited from a common
ancestor

18. HOMOLOGOUS ANALOGOUS
Same origin but
different functions
Same function but
different origin

ANALOGOUS

GENETIC
EVIDENCE

20. ● Mutations (changes)in DNA provide a source
of genetic variation
● Commonalities in DNA between all
organisms on Earth provide evidence for
common descent.
● Slight differences is the genetic code reflect
branching evolutionary relationships.
HOW DOES DNA
RELATE TO EVOLUTION?

21. Humans and chimps share a surprising 98.8 percent of their DNA.

CONCLUSION

24. ● Homo sapiens are the apex beings of our world today
● But on seeing the grand scheme, we’re the youngest beings
on Earth.
● Our existence of about 200k years is nothing compared to
the other organisms or even our hominin ancestors who
lived longer than us
● Adaptation, natural selection, and genetical evolution
shaped our species to what we’re today and is still shaping
us toward the future
