Environmental evolution occurs when environmental changes force organisms to adapt in order to survive. There are three main types of environmental evolution: divergent evolution where species adapt to new habitats, convergent evolution where unrelated species develop similar traits to adapt to the same environment, and parallel evolution where species evolve independently but maintain similar traits. Human activities like climate change, habitat loss, pollution and invasive species are putting pressure on populations and influencing evolutionary processes. The future environment is expected to be warmer with rising seas, changing precipitation patterns, and more extreme weather depending on how much greenhouse gas emissions are reduced.

1. ENVIRONMENTAL EVOLUTION

2. What is Environmental Evolution
Environmental means concerned with the protection of the
natural world of land, sea, air, plants, and animals.
Evolution is possible when there is variation in the genetic
makeup among organisms that affects their traits. Then, if certain
individuals in a population reproduce more successfully than others
so that their traits become more common within the population,
the result is evolutionary change.

Introduction
The traditional view is that ecology
shapes evolution. The environment defines a
template for the process of evolution: natural
selection shapes organisms to fit that template.
Some studies suggest, however, that
evolutionary processes reciprocate by
influencing ecology.
How is environment related to evolution?

4. Environmental Evolution
What is evolution
environmental
science?
is the change in the genetic makeup of a
population over time. This means that the
genes, and the traits they control are
changing over many generations in a
specific population. Evolution is the cause
of speciation, where new species form
due to pressures in the environment.

5. Environmrntal evolution
Environmental evolution
examples
Erupting volcanoes
Erupting volcanoes cause
sudden, drastic change in an
area, forcing organisms to
evolve rapidly to adapt to the
new environment.

6. Environmrntal evolution
Change in an organism's
environment forces the
organism to adapt to fit the
new environment, eventually
causing it to evolve into a
new species
Change and Isolation
For example, if a species of
animal is mostly limited to
eating one kind of leaf, and a
change occurs: a fungus attacks
and kills most of that kind of
plant, the animal has to evolve
either to fight the fungus or to
eat something else.

microevolution
Microevolutionary processes
are changes in allele frequencies
in a population over time. n add
it to the actual.
macroevolution
Macroevolution, on the other
hand, refers to change at or
above the level of the species.
Two general classes of evolutionary change

8. DIVERGNT
This type of evolution often
occurs when closely related
species diversify to new
habitats. On a large scale,
divergent evolution is
responsible for the creation
of the current diversity of life
on earth from the first living
cells.
CONVERGENT
Convergent evolution causes
difficulties in fields of study such as
comparative anatomy. Convergent
evolution takes place when species
of different ancestry begin to share
analogous traits because of a shared
environment or other selection
pressure. For example, whales and
fish have some similar characteristics
since both had to evolve methods of
moving through the same medium:
water.
PARALLEL
EVOLUTION
Parallel evolution occurs when
t w o s p e c i e s e v o l v e
independently of each other,
maintaining the same level of
similarity. Parallel evolution
u su a l l y o cc u r s be t we e n
unrelated species that do not
occupy the same or similar
niches in a given habitat.
What are 3 types of evolution?

9. How Human Activities Influence
Evolution
Human effects on the biosphere have
been dramatic. Much of our impact on
evolutionary processes is due to
activities that cause declines in species
populations, including
Anthropogenic climate change, including
global warming.
Habitat loss, often from agricultural
activities, deforestation, and/or urbanization.
Hunting and fishing for food or sport.
Degrading ecosystems, especially soil, water,
and air from pollution and waste.
Invasive species that put enormous pressures
on populations by disrupting species
interactions.

10. Human impact on the
environment
refers to changes to biophysical
environments and
to ecosystems, biodiversity, and natural
resourcescaused directly or indirectly by
humans. Modifying the environment to fit
the needs of society is causing severe
effects including global
warming, environmental degradation. such
as ocean acidification, mass
extinction and biodiversity loss, ecological
crisis, and ecological collapse. Some human
activities that cause damage (either directly
or indirectly) to the environment on a global
scale include population growth,
overconsumption, overexploitation,
pollution, and deforestation. Some of the
problems, including global warming and
biodiversity loss, have been proposed as
representing catastrophic risks to the survival
of the human species

11. What will the environment be like in the
future?
• Future changes are expected to include a warmer atmosphere, a
warmer and more acidic ocean, higher sea levels, and larger changes
in precipitation patterns. The extent of future climate change
depends on what we do now to reduce greenhouse gas emissions.
