Evolution | One Shot Video

Lamarckism:
This theory, proposed by Jean-Baptiste Lamarck, suggests that organisms evolve through the inheritance of acquired characteristics.
Essentially, Lamarck believed that traits developed during an organism’s lifetime, such as a giraffe stretching its neck to reach higher leaves, could be passed on to its offspring.
This idea has largely been discredited in favor of other evolutionary theories.

Darwinism:
Charles Darwin’s theory of evolution, often referred to as Darwinism, is based on the idea of natural selection.
Darwin proposed that species evolve over time through a process where individuals with advantageous traits are more likely to survive and reproduce. This concept emphasizes the role of environmental pressures in shaping the development of species.

Neo-Darwinism:
Neo-Darwinism combines Darwin’s theory of natural selection with modern genetics. It incorporates the understanding of genetic variation and inheritance, refining Darwin’s ideas by explaining how genetic mutations and recombination contribute to evolutionary changes.
Neo-Darwinism aligns with the modern synthesis of evolutionary biology.

Evidence of Evolution:
Evidence for evolution includes:

Fossil Record: Shows a chronological sequence of life forms, illustrating gradual changes and transitional forms.

Comparative Anatomy: Demonstrates homologous structures (similar anatomical features in different species due to common ancestry) and vestigial organs (reduced or non-functional structures).

Genetics: Reveals similarities in DNA sequences among different species, indicating common ancestry.

Embryology: Highlights similarities in the early developmental stages of different species, suggesting evolutionary connections.

Biogeography: Examines the geographical distribution of species, providing insights into how species have evolved and spread over time.
