Evolutionary Impacts of Ivory Poaching

Hello. I am Joshua and theology.

And this is my video presentation project for bio 1 82 lab

and below is my work cited.

The news story I've chosen for this assignment is

titled wino tusk poaching tip scales of elephant evolution.

This new news article is about how elephants are rapidly evolving to have no tusks.

This rapid evolution is credit to the environment that they

are in as they are subject to high levels approaching

the environmental stress and pressures are so much that there

evolving fast in order to combat

the environmental stress of the increase poaching.

The primary literature for

the news article I have chosen is cited below and it

is titled ivory poaching and the rapid evolution of tusk listening

and african elephants

is a research paper done by Shane. See Campell

Stanton

brian, J.

Arnold, dominick, dunne, cannabis, peter, Granelli, Joyce poole,

Ryan along and robert M.

Pringle.

The main topics of the primary literature

is

It talks about human advancements and poaching and this was a paper done

and done in 2022.

They go over the fact that the pressures are so small scale that they can be

considered selective drivers of natural selection and therefore

a driving force and evolution of these elephants.

Um They note that increased poaching done by armed forces during Mozambique.

The mozambican civil war

between from 1977 and 1992

is a contributor to these

changes.

Um they note that elephant populations declined by 90% during the time

of this war and they also noticed that post war and during

the recovery of this population, female elephants were born tuscaloosa

and as one of their main pieces of evidence they use

while signing this paper.

Mhm.

There is the data from the primary literature

you can see in the first

in graph a

it shows the population size of

three different types of elephants on the very left. You see

um more than 50%, about 64% of the elephants were

um the labeled as to type elephant which is um full grown tusk elephants.

And that is from the in the year 1970.

And then if you go over to 2000, we now see that 50.9% are

group D elephants which are tusked

elephants

and

only 40.7% are

Group two elephants which are again full length of tusk elephants.

And then we can also see the survival

survive tuscaloosa survival bias

and chart, see

how does this connect bio 1 82.

This New Hours news article heavily connects to the

ideas we have learned throughout bio 1 82.

The news source covers topics like evolution, natural selection,

parasitic relationships and environmental pressures

because

and shows how all these things are intertwined and related on uh on each other.

The information presented in the news source is relevant and accurate

and also directly relates to the topics we've been exposed to.

Throughout this course,

we know that this

information is accurate because

we see,

We are clearly shown that poaching is increased during the

time of the Mozambican Civil War. And we can see that 90% of

The elephant population, the elephant population decreased by 90%. So

with that decrease in population and that increase in

poaching, we now have a population that is regrowing. And

with this re growing population from the data tables we can see

die,

hi, majority of them are growing back tuscaloosa

and this can be attributed to small scale selective pressures that are

a mechanism of natural selection. Because natural selection is now favoring the

tuscaloosa

elephants due to the fact that the tusked elephants with tusks are dying

and being poached for their tusks on natural selection is favoring the tusla

elephants and therefore natural selection is gonna be a driving

force for an evolutionary change in the elephant population.

Thank you.
