• Hunting pandas is now illegal in China
– Hunted by humans
• Deforestation caused bamboo plants to decrease significantly‐ Significant part of Panda Diet
• Pandas then had to move to where Bamboo grows (couldn't’t wait for new Bamboo to grow because this can take up to 100 years)
– Deforestation
Giant Panda
• Pandas moved because:
Move 1

• As a result of abundant resources close by, the locusts were able to expand their habitat range. – More resources close by
Locust
• Locusts moved because:

The desert
Hot, barren, little food and water
Adapt 1
Yes, it allows them to go for days without eating. Whales have fat (blubber) all over their bodies to stay warm. The camel would get too hot. Hump
Fat
–
–
Might get too hot if fat stored around body
Might not be able to go for long periods without food and water
What would happen if a camel was born without the ability to form a hump? –
What is stored in a camel’s hump? –
What adaptation do camels have? –
Why would fat all over a camel’s body be a problem?
–
Why do whales have fat (blubber) all over their bodies?
–
Fat is stored by animals so that when needed it can be released as energy in replacement of eating food and drinking water. Do you think fat is important for camels?

Savannah, grassy plains
Grass, some tall trees
Zebras, lions, gazelles, etc. Grass Yes, from zebras, gazelles, etc. Leaves of trees
Being taller Adapt 2
Neck
Giraffe’s with longer necks need more nutrients and during a drought it is harder to get these nutrients therefore there is a check and balance system. In addition, leaves during a drought grow lower to the ground which make competition for the long neck giraffes with other giraffes. –
Might not have enough food to survive. What would happen if a giraffe was born with a short neck? –
Why don’t giraffe’s necks keep evolving to get longer and longer?
–
What adaptation do the giraffes have to allow them to eat the alternative food source of trees?
–
What would help animals be able to eat leaves on a tree?
–
Besides grass, what else could plant eating animals eat?
–
Do you think there is competition for food that giraffes might eat?
–
What do zebras and gazelles eat? –
What other animals liver there?

After all of the large prey died off, saber‐toothed cats were not able to catch smaller prey (such as mice) and did not have enough to eat. This led to their extinction. – No, it would be hard because their two large teeth would get in the way. Do you think that saber‐toothed cats were able to catch smaller prey such as a mouse?
– Large prey
What did saber‐toothed cats eat?
– Large teeth to catch prey
Saber‐Toothed Cat (extinct 7.2 million years ago)

– It is more beneficial for a species to be spread out over a large area. • Is it beneficial for species to be in larger or smaller areas? – It takes a long time! Over multiple generations. Little Swan Island Hutia (extinct in 1955)
• Lived on a small island in Honduras
• Hurricane came and devastated the island. In addition, house cats were introduced to the island, which played a role in the extinction. • This rodent could not adapt quick enough and thus died off and became extinct. • How long does it take for a species to make adaptations?
