Let's solve this step-by-step based on the image you've provided, which is a worksheet about human evolution.

Part 1: Match the names to each picture

We are given four hominin species:
- Homo Sapiens
- Homo Habilis
- Homo Erectus
- Homo Neanderthalensis

And four illustrations of early humans in evolutionary order (left to right).

#### Step-by-step identification:

1. First figure (leftmost) – This one has a more ape-like posture, smaller brain, and curved spine. It’s not fully upright.
- This is not Homo sapiens or Neanderthalensis.
- It resembles Homo Habilis, who was one of the earliest members of the *Homo* genus with larger brains than earlier hominins but still had some primitive features.
- However, note that Homo Habilis is often depicted as more upright than this figure.

But wait — looking at the order of evolution, from left to right, it should go:
- Earliest → Most recent

Let’s analyze the figures carefully:

- Figure 1: Hunched back, ape-like, small head → likely an early hominin, but not one of the listed species? Wait — all four options are *Homo* species.

Actually, the first figure looks more like Australopithecus, but since only *Homo* species are listed, we must assume the first one is meant to be Homo Habilis, which is the earliest *Homo*.

So:
- Homo Habilis – earliest *Homo*, still somewhat apelike, but walks upright.

2. Second figure – More upright, larger brain, prominent brow ridge, maybe a bit less hunched.
- This could be Homo Erectus — known for being fully upright and having longer legs.

3. Third figure – Very robust build, heavy brow ridge, large nose, thick bones.
- This is Homo Neanderthalensis — they were stocky, adapted to cold climates.

4. Fourth figure – Modern human build, slender, narrow face, high forehead.
- This is Homo Sapiens.

But wait — the sequence seems backwards?

No — let’s look again at the direction of evolution:

In most evolutionary diagrams, time moves from left to right, so the earliest form is on the left, and the most recent on the right.

So the correct order should be:

1. Homo Habilis – earliest *Homo*
2. Homo Erectus – next
3. Homo Neanderthalensis – evolved later
4. Homo Sapiens – most recent

But visually:

- Figure 1: Hunched → Homo Habilis
- Figure 2: Upright, but still robust → Homo Erectus
- Figure 3: Stocky, strong build → Homo Neanderthalensis
- Figure 4: Modern human → Homo Sapiens

✔ That matches.

So the matching is:

| Picture | Name |
|--------|------|
| 1st (left) | Homo Habilis |
| 2nd | Homo Erectus |
| 3rd | Homo Neanderthalensis |
| 4th (right) | Homo Sapiens |

> ⚠️ Note: Some sources suggest Homo Erectus came before Homo Neanderthalensis, and both coexisted briefly. But Homo Sapiens is the latest.

So the correct drag-and-drop answers are:

1. Homo Habilis
2. Homo Erectus
3. Homo Neanderthalensis
4. Homo Sapiens

Part 2: True or False

Now evaluate each statement:

#### 1. Humans EVOLVE from dinosaurs.
✘ FALSE
Humans did not evolve from dinosaurs. Dinosaurs went extinct ~66 million years ago. Humans evolved from early primates, which shared a common ancestor with other primates (like chimpanzees), not with dinosaurs.

> ✔ Correct answer: FALSE

---

#### 2. Hominization is the process of change in lions.
✘ FALSE
Hominization refers to the evolutionary process by which hominins (human ancestors) developed traits like bipedalism, larger brains, and tool use. It’s not about lions.

> ✔ Correct answer: FALSE

---

#### 3. Homo Sapiens is the first stage in the hominization process.
✘ FALSE
Homo Sapiens is the latest stage. The process started with early hominins like *Australopithecus*, then *Homo Habilis*, *Homo Erectus*, etc., leading to *Homo Sapiens*.

> ✔ Correct answer: FALSE

---

#### 4. Homo erectus walked in two legs at all times.
✔ TRUE
*Homo erectus* is known for being fully bipedal — they walked upright on two legs efficiently, unlike earlier hominins who may have had more variable locomotion.

> ✔ Correct answer: TRUE

---

#### 5. Homo Neanderthalensis lived in caves.
✔ TRUE
Neanderthals often lived in caves and rock shelters, especially in Europe and Western Asia. They used natural shelters for protection and warmth.

> ✔ Correct answer: TRUE

---

✔ Final Answers:

#### Part 1: Matching
From left to right:
1. Homo Habilis
2. Homo Erectus
3. Homo Neanderthalensis
4. Homo Sapiens

#### Part 2: True or False
1. False
2. False
3. False
4. True
5. True
