真的是遗传吗？

可以这样继承吗？我只是得到错误：

class Human:public Node<Human>; //Здесь unknown template name 'Node' и expected '{' after base class list

template <class T>
class Node{
private:
    T data;
    QList<Node<T>*> childs;
    QList<Node<T>*> parents;

public:
    Node(){
        qDebug( "Node construct" );
    };
    Node(T* newdata){
        qDebug( "Node construct" );
        data = *newdata;
    };
    T get_data(){ return data; }
    void set_data(T new_data){data=new_data;}
    void add_child(T* child){ childs.push_back(new Node(child));}
    void add_parent(T* parent){parents.push_back(new Node(parent));}

    QList<Node<T>*>* get_childs(){return &childs;}
    QList<Node<T>*>* get_parents(){return &parents;}
    ~Node(){

    }
};

class Human:public Node<Human>{ // А здесь redefinition of 'Human'
private:
    int id;
    Node<Human> *node = new Node<Human>();
    Photo avatar;
    QString firstname;
    QString lastname;
    QString description;
    Gallery gallery;
    QList<Event*> events;
public:
    Human(){}
    Human(QString firstname,QString lastname,QString description):firstname(firstname),lastname(lastname),description(description){};
    QString get_firstname();
    QString get_lastname();
    Photo get_avatar();
    QList<Event *> get_events();
    Gallery get_gallery();
    void change_firstname(QString);
    void change_lastname(QString);
    void change_description(QString);
    void add_child(Human*);
    void add_parent(Human*);
    QList<Node<Human> *> *get_childs();
    QList<Node<Human> *> *get_parents();
};
